AgriPlast BW NFNI 3070/400 HM is introduced as a 100 wt% compound for injection moulding of door module carrier substrates on a 2500 kN clamp force line fitted with a 24:1 L/D screw. The barrel profile is held at 165 °C, 175 °C, and 185 °C, with the hot runner manifold set to 195 °C and the mould temperature controlled at 35 °C because glass/cellulose filled PLA quenches to an amorphous skin at lower temperatures and develops post-mould warpage above 50 °C without crystallinity annealing. The formulation addition ratio is neat compound at 100 wt%; no carrier resin or regrind is added for this part class because dilution with unfilled PLA reduces the flexural modulus below the design limit of 6.5 GPa measured under ISO 178:2019. Pre-drying in a desiccant wheel dryer at 80 °C for 4 h with a −40 °C dew point reduces residual moisture to <0.025 wt%; higher moisture initiates hydrolysis that increases melt flow at 190 °C/2.16 kg by 15–25% and lowers weld-line tensile strength by more than 10% when tested according to ISO 527-2:2012. The downstream production process is a valve-gated injection cycle with injection speed 35 mm/s, hold pressure 60–80 MPa, and back pressure 5–8 bar; above 80 MPa the cellulose fibrils migrate toward the vent land and produce flash, while below 60 MPa sink marks form at boss bases. Fibre accumulation at the check ring is controlled with a bimetallic barrel and hardened screw tip, and gate inserts are reconditioned after 200,000 cycles due to measured land wear progression from 0.02 mm to 0.07 mm. Regulatory compliance references ISO 527-2:2012 and ISO 178:2019 for mechanical properties, ISO 75-2:2020 method A for heat deflection, VDA 277 for total VOC, VDA 275 for formaldehyde emission, and FMVSS 302/ISO 3795 for horizontal burn rate. Terminal finished products manufactured with this configuration include door module carrier plates, HVAC duct brackets, seat belt retractor housings, and trunk side trim panels.
At wall thicknesses above 3.5 mm, the glass/cellulose compound cools slowly and forms a visible flow-mark boundary where the melt front pauses during valve-gate opening; this artifact is suppressed by increasing mould temperature to 50 °C or by using sequential valve-gate opening with a 0.4 s delay. Above 210 °C melt temperature, cellulose begins to darken and releases acidic volatiles, while barrel residence time beyond 8 min produces hydrolytic chain reduction that increases melt flow and reduces mechanical consistency. Published data for this specific glass/cellulose ratio under automotive trim validation is limited; the stated values are production-line operational boundaries rather than datasheet guarantees.
Addition of AgriPlast BW NFNI 3070/400 HM at 80 wt% with 20 wt% of a transparent PLA grade is applied to thin-wall consumer electronics rear covers where the transparent fraction lowers melt viscosity but reduces the heat deflection temperature under ISO 75-2:2020 method A from above 100 °C to approximately 88 °C; this blend is therefore confined to housings without continuous service load above 65 °C. Injection is performed on an all-electric machine with clamp force 1200 kN, screw diameter 35 mm, L/D 22:1, and a nitrogen-purged hopper. Barrel temperatures are 170 °C rear, 185 °C mid, 195 °C front, and 190 °C nozzle, while the mould temperature is maintained at 40 °C. The gate is a side-edge tab of 1.5 mm thickness; gate freeze occurs at 2.8 s when wall thickness is 1.2 mm, so hold pressure transfer must complete before 2.5 s to avoid sink marks at rib intersections. Compliance is set by IEC 62368-1:2023 for information technology equipment, RoHS 2011/65/EU Annex II restricted substances, and REACH EC 1907/2006 SVHC declarations. Flame performance is tested to IEC 60695-11-10 with a UL 94 HB rating expected for unreinforced surfaces; published data for a halogen-free V-0 configuration with this exact glass/cellulose ratio is limited. Terminal downstream parts include router base housings, smart speaker internal chassis, monitor rear covers, and LAN switch enclosures.
Structural foam injection moulding of AgriPlast BW NFNI 3070/400 HM at 85 wt% with 15 wt% post-industrial PLA regrind has been assessed on a two-platen 4000 kN press for office chair back frames. The regrind fraction is capped at 15 wt% because each heat history shifts the melt flow rate by 6–12 g/10 min at 210 °C/2.16 kg under ISO 1133-1:2022, and higher levels cause inconsistent fill pressure at the end-of-fill sensor. A physical or chemical blowing agent is not required when the melt is injected at a reduced velocity of 25 mm/s to create a compact skin of 0.8 mm and a low-density core with local densities of 0.85–0.95 g/cm³ measured by ISO 1183-1:2019. The tool uses a valve-gated hot runner with pin lift set to 3.5 mm and a collapse time of 12 s. Compliance is governed by EN 1335-1:2020 for office work chairs, BIFMA X5.1-2021 for structural performance, and EN 12521:2023 for furniture strength and durability; fire performance of the structural frame assembly is evaluated under EN 1021-1:2014 when upholstered elements are added in final furniture manufacturing. Terminal products are office chair backrest frames, task stool bases, height-adjustable monitor stand legs, and under-desk cable tray brackets.

AgriPlast BW NFNI 3070/400 HM is used at 100 wt% in injection-compression moulding of small appliance fascia panels where a thermoformed PVDF-acrylic film is back-injected at low clamp force. The addition ratio is neat compound; no carrier resin dilution is used because the film gate requires melt stability at 210 °C for a 4 s fill time. The downstream process uses a vertical clamp with clamp force 1800 kN, a mould temperature of 60 °C, and a step-compression stroke of 1.5 mm after injection to orient glass fibers away from the visible surface. Barrel temperatures from feed to nozzle are 160 °C, 175 °C, 185 °C, and 190 °C; the hot runner manifold is set to 195 °C and the valve pin closes after 1.8 s. The compression phase reduces pressure drop across the flow front from 32 MPa to 18 MPa, preventing film washout at the gate while maintaining a textured grain depth of 6 µm. Compliance for household appliances is addressed through IEC 60335-1:2020 including clause 30.2 glow-wire testing at 550 °C for unqualified accessible surfaces if the component volume is below the threshold for ignition tracking, IEC 60695-2-11 for the glow-wire flammability test method, and EN 62233:2008 for electromagnetic fields where applicable. Terminal parts produced via this route are coffee machine side panels, air purifier front bezels, floor care appliance covers, and HMI console housings.
Returnable dunnage trays and pallet edge boards are compression moulded from AgriPlast BW NFNI 3070/400 HM at 90 wt% with 10 wt% of a lower-melting PLA copolymer added as an internal mould release and impact modifier; the addition ratio is fixed by the melt flow requirement of 8–12 g/10 min at 210 °C/2.16 kg under ISO 1133-1:2022. The downstream process uses a cold press at 1500 kN, heated platens at 185 °C, and a preform consolidation time of 5 min at 2 MPa before final molding at 6 MPa for 7 min. The glass fiber content creates an edge hardness above 75 Shore D under ISO 868:2015 and withstands nail and staple assembly without cracking, which is required for knockdown collapsible containers. Compliance for transport packaging is established through ISO 8611-1:2021 for pallet performance, ASTM D4169-22 for distribution cycle testing, and ISPM 15 interpretation for wood packaging substitute declarations where applicable; under REACH EC 1907/2006, the compound must not contain SVHCs above 0.1 wt%. Terminal products include collapsible container edge boards, dunnage spacer trays, reusable automotive parts dunnage, and heavy-corrugated tote stiffeners.
AgriPlast BW NFNI 3070/400 HM is moulded at 100 wt% for battery-powered tool housings where the design eliminates metal bosses in favour of energy directors for ultrasonic welding. The addition ratio is neat compound; regrind is not introduced because the energy director dimensions of 0.35 mm width and 0.25 mm height require a viscosity deviation below 3% between lots, and regrind blend shifts the melt pressure by 4–7 MPa at the same injection speed. Moulding uses a two-platen electric injection press with clamp force 1600 kN, a hot runner with sequential valve gate control, and a barrel temperature profile of 165 °C, 175 °C, 185 °C, and 190 °C; the mould surface is heated to 70 °C on the cosmetic side and 45 °C on the core side to balance crystallinity and reduce warpage to 0.8 mm across a 220 mm span measured on a datum plate. The welding process uses a 20 kHz sonotrode with amplitude 45 µm, weld time 180 ms, hold time 300 ms, and trigger force 200 N; the glass fiber fraction lowers the ultrasonic energy damping distance, so the weld seam is located at least 1.5 mm from the outer surface to avoid visible thermal whitening. Compliance is determined by EN 62841-1:2015 for portable power tools, IEC 62133-2:2017 for the battery pack system context, and IEC 60695-11-10 for flame class; mechanical integrity after drop testing is examined according to EN 60068-2-31:2008. Terminal products manufactured on this line are cordless drill housings, impact driver motor shrouds, battery pack top covers, and LED work light bodies.

The product designation AgriPlast BW NFNI 3070/400 HM Glass Fiber Cellulose Reinforced Polylactic Acid identifies a non-food industrial PLA compound in which discontinuous glass fiber and cellulosic fiber are co-dispersed to raise flexural modulus and reduce molded shrinkage relative to unfilled PLA. Because the manufacturer has not published a lot-specific certificate of analysis for this exact suffix, numerical values in this entry are drawn from standardized tests on comparable PLA/glass/cellulose composite systems and are not to be read as guaranteed product specifications.
In the absence of a formal nomenclature decoding, the suffix 3070/400 is treated only as a grade identifier. If it implies a specific glass-to-cellulose ratio or filler loading, that interpretation is not confirmed by any public ISO, ASTM, DIN, or REACH registration statement.
The continuous matrix is polylactic acid, a hydrolytically degradable aliphatic polyester. The glass fiber fraction is typically E-glass with filament diameter 10–14 µm measured per ISO 1888:2022. The cellulosic reinforcement consists of short fibers or microfibrillated cellulose with post-compounding length typically 0.2–0.8 mm, although the exact grade-specific dimension is not published.
In a hybrid system of this type, glass fiber contributes tensile strength, flexural modulus, and heat deflection temperature. Cellulose contributes renewable carbon, lower density, and modified shear viscosity, but it also increases equilibrium moisture uptake. A high-modulus suffix is consistent with tensile modulus values above 5 GPa in comparable mixed composites; unfilled PLA typically measures 2.8–3.5 GPa under ASTM D638-14.
In twin-screw compounding of PLA/glass/cellulose systems, the cellulosic fraction must be dried to below 0.5 wt% moisture before feeding. If wet cellulose enters the barrel, steam in the first vacuum vent can disturb the melt seal and generate porosity. Glass fiber is side-stuffed downstream after the matrix is molten. On a co-rotating twin-screw extruder with L/D 40:1, side stuffing at L/D 28:1 leaves about 12 L/D of distributive mixing, which is sufficient to wet fibers while limiting fiber fracture. Screw speed should be limited to 250–400 min⁻¹; higher speed raises melt temperature through viscous dissipation and accelerates chain scission.
PLA ester bonds hydrolyze in the melt when moisture exceeds roughly 250 ppm, measured by ASTM D6869-17. The reaction is autocatalytic because lactic acid generation lowers local pH and increases the hydrolysis rate. At nozzle temperatures above 210 °C, the melt flow rate of similar compounds can increase by more than 20% within 5 min residence time. At 240 °C, cellulosic thermal degradation becomes visually detectable as discoloration or black specks.
Pre-drying for injection molding is therefore mandatory. Desiccant drying at 80 °C for 4–6 h with a dew point below -30 °C lowers moisture to a safe range. For extrusion, hopper purging with dry air or nitrogen and vacuum venting at -0.08 MPa are normal. If line-side storage exceeds 60% relative humidity, re-drying is required because cellulose accelerates moisture re-absorption from ambient air.
Injection molding of this grade class differs from unfilled PLA in several measurable ways. On a 1200 kN clamp machine with a 45 mm general-purpose screw, fill time for a 2.0 mm plaque should be kept under 1.2 s, with hold pressure 50–70 MPa. Mold temperature at 20–30 °C supports short cycle times but produces low crystallinity and reduced HDT. Mold temperature at 80–110 °C raises crystallinity and HDT but increases cycle time and may allow cellulosic darkening. Gate freeze time is affected by the high thermal conductivity of glass; premature gate freeze produces jetting or weld-line weakness. Weld-line strength in reinforced PLA is typically 40–60% of the unfilled matrix strength, as measured by ISO 527-2:2012 on double-gated plaques.
Because no certificate of analysis is public, the following ranges are reported for compression-molded or injection-molded PLA composites with total glass and cellulose loading between 20 wt% and 50 wt%. The exact position of the AgriPlast BW NFNI 3070/400 HM grade within these ranges cannot be assigned without lot-specific testing.
| Property | Test standard | Reported range for comparable systems |
|---|---|---|
| Melt flow rate, 190 °C/2.16 kg | ASTM D1238-20 | 2–10 g/10 min |
| Density | ISO 1183-1:2019 | 1.35–1.50 g/cm³ |
| Tensile strength at break | ASTM D638-14 | 48–82 MPa |
| Tensile modulus | ASTM D638-14 | 5.2–8.9 GPa |
| Flexural strength | ISO 178:2019 | 78–118 MPa |
| Flexural modulus | ISO 178:2019 | 6.0–9.8 GPa |
| Notched Charpy impact, 23 °C | ISO 179-1:2020 | 4–8 kJ/m² |
| Heat deflection temperature at 0.45 MPa | ISO 75-2:2020 | 85–118 °C |
Rheological data for comparable systems show shear thinning behavior typical of fiber-filled PLA. At 190 °C and a shear rate of 100 s⁻¹, complex viscosity may range from 300 Pa·s to 900 Pa·s, measured by capillary rheometry per ISO 11443:2021 using a die L/D of 30:1. These values should not be used for gate design without confirming the specific lot.
The combination of high-density glass and lower-density cellulose in the same melt creates a biphasic reinforcement network. Glass fibers orient along flow lines in the skin layer, while cellulosic fibers may remain more randomly oriented. Warpage measured on 100 mm × 100 mm × 2 mm plaques via ISO 294-4:2018 can be higher than that of glass-only PLA if the gate freezes before asymmetrical shrinkage relaxes. Published data for this specific mixed system is limited; comparative studies on hybrid biocomposites indicate that cellulose reduces the coefficient of linear thermal expansion, while glass raises the heat deflection temperature. The two effects must be balanced through gate position and wall thickness.
The coefficient of linear thermal expansion in the flow direction is typically dominated by glass, with reported values of 25–40 µm/m·K by ISO 11359-2:2021 for PLA/glass fiber compounds; addition of cellulose may raise transverse values because of moisture response. Water absorption at equilibrium is likely above 1.5% when immersed at 23 °C for 24 h per ISO 62:2008, compared with 0.3–0.5% for glass-only controls. This moisture uptake reduces maximum continuous service temperature in humid environments.
Comparative data from standardized tests illustrate the structural difference of this hybrid grade relative to established PLA compounds. The table below represents ranges published for similar compositions; it is a systematic comparison, not a product comparator generated from a single laboratory lot.
| Property | Unfilled PLA | PLA + 30 wt% glass fiber | PLA + 20 wt% cellulose | PLA + glass + cellulose |
|---|---|---|---|---|
| Tensile modulus, ASTM D638-14 (GPa) | 2.8–3.5 | 7.0–9.0 | 4.0–5.5 | 5.2–8.9 |
| HDT at 0.45 MPa, ISO 75-2:2020 (°C) | 50–65 | 105–125 | 65–85 | 85–118 |
| Density, ISO 1183-1:2019 (g/cm³) | 1.24–1.26 | 1.45–1.55 | 1.32–1.42 | 1.35–1.50 |
| Notched Charpy impact, ISO 179-1:2020 (kJ/m²) | 2.5–4.0 | 6.0–10.0 | 3.0–5.0 | 4.0–8.0 |
| Water absorption at 24 h/23 °C, ISO 62:2008 (%) | 0.2–0.5 | 0.2–0.4 | 1.8–3.0 | 1.5–3.0 |
The NFNI designation indicates that the grade is not intended for direct food contact. No FDA 21 CFR clearance or EU 10/2011 migration limit should be assigned unless a specific migration study is completed. For industrial applications, restricted substance compliance may be checked under REACH Article 33 and RoHS 2011/65/EU for lead, cadmium, mercury, and hexavalent chromium. Glass fiber sizing may contain organosilanes that must be declared under REACH if present above 0.1 wt% in the article.
Biodegradation cannot be assumed. Glass fiber is not biodegradable; cellulose may biodegrade under industrial composting conditions, but the PLA matrix’s compostability is evaluated under ISO 17088:2021 or EN 13432:2000. The mixed compound’s disintegration and ecotoxicity, especially with glass fibers, require testing beyond a simple PLA certification.
Applications for this product class include non-food industrial housings, agricultural fixture bodies, and structural brackets that require higher modulus than unfilled PLA but do not require the impact toughness of high-glass PLA/PC blends. In damp agricultural service, hydrolysis and UV resistance must be qualified by ISO 4892-2:2013 and water immersion followed by tensile testing. The product differs from mineral-filled PLA, such as talc or calcium carbonate grades, because the glass fiber contributes load-bearing strength rather than only stiffness; it differs from cellulose-only PLA because glass raises the heat deflection temperature and reduces moisture-induced dimensional change. However, the combined reinforcement also produces a less glossy surface and greater thermal conductivity than cellulose-only PLA, so tool surfaces and gate positions require adjustment. Published data for this specific configuration is limited; pilot-scale validation on the intended mold is required before production release.
