Jiangsu Xinfuda ABS H1100 H is a pelletized acrylonitrile-butadiene-styrene copolymer manufactured by Jiangsu Xinfuda Chemical Co., Ltd. The grade designation consists of the polymer class ABS, the numerical sequence 1100, and the letter suffix H. The supplier has not placed a complete English-language technical datasheet for this exact grade in common open resin databases; therefore, specification values assigned to H1100 H must be verified against a batch-specific certificate of analysis before production release. The polymer system consists of a styrene-acrylonitrile continuous phase and a dispersed polybutadiene rubber phase. Acrylonitrile continues to contribute resistance to aliphatic hydrocarbons and stress-cracking media, butadiene continues to provide impact energy absorption, and styrene continues to govern rigidity and melt processability. Molecular mass distribution, rubber particle size distribution, grafting ratio, and heat stabilization are grade-specific variables that separate H1100 H from other ABS resins. Under ISO 2580-1:2003, an ABS designation block encodes Vicat softening temperature, melt volume-flow rate, notched impact strength, and tensile modulus; the designation block for H1100 H should be requested from Jiangsu Xinfuda before tool design.

Commercial ABS resins with an H suffix in Chinese trade nomenclature may indicate high heat resistance, high impact resistance, or a production-line extension. Published data for this specific configuration is limited. The letter suffix cannot be assigned a fixed processing or performance meaning without supplier documentation. Incoming resin qualification should therefore measure melt flow rate under ISO 1133-1:2022 at 220°C and 10 kg, density by ISO 1183-1:2019, and Charpy notched impact by ISO 179-1:2010 before lot acceptance.

What published property ranges frame the H1100 H processing envelope?

Because the exact datasheet values for H1100 H are not fully open, the following typical ranges for commercial ABS resins establish a bounding envelope for initial machine-setting calculations. These ranges are not lot-specific release values and should not be used as acceptance limits for H1100 H.

The melt flow value is the strongest classification variable. Injection molding grades typically fall between 15 and 45 cm³/10 min, while sheet and profile extrusion grades commonly remain between 4 and 10 cm³/10 min. The H1100 H grade must be assigned to one of these processing windows by the certificate of analysis; differences of more than ±2 cm³/10 min from the nominal supplier value can alter fill pressure, residence time in hot runners, and part mass consistency.

Capillary rheometry per ISO 11443:2014 at 230°C and an apparent shear rate of 1000 s⁻¹ typically shows apparent shear viscosity values between 120 Pa·s and 280 Pa·s for general-purpose ABS. High-flow variants occupy the lower end, while extrusion products occupy the upper end. The shear-viscosity curve of H1100 H should be measured in the production laboratory because the relationship between melt flow rate and shear viscosity is not linear across grades with different rubber particle size distributions.

Drying conditions for the moisture-sensitive ABS matrix are mandatory. H1100 H should be dried to a residual moisture level below 0.05 wt% using a desiccant dryer with a dew point of −40°C or lower. A drying temperature of 80°C for 2 to 4 h is conventional for ABS; at ambient relative humidity above 60%, the dwell time should be extended to 4 h and the material should be processed within 30 min of hopper discharge. Moisture above the threshold causes surface splay, silver streaks, and observable blisters in extruded sheet. On an injection molding machine, a barrel profile from feed to nozzle of 210°C, 220°C, 230°C, 235°C, and 240°C is a conservative starting point for general-purpose ABS; mold temperatures between 40°C and 80°C control surface gloss, weld-line strength, and post-molding shrinkage. The last three heated zones should be held within ±5°C of setpoint when high-gloss parts are produced because temperature variation above this band creates visible gloss bands and increases the risk of local thermal degradation.

Lot release testing on a production-scale injection molding machine should include a fill study at 220°C, 230°C, and 240°C with shot volume held at 70% of barrel capacity. Short-shot comparisons at fixed transfer pressure identify lot-to-lot flow variation. Part mass variation above 0.5% at stable cushion and hold pressure indicates lot flow drift or check-ring wear. On a capillary rheometer, the shear viscosity ratio at 100 s⁻¹ and 1000 s⁻¹ provides a simple indicator of shear sensitivity; values below 2.0 suggest more Newtonian flow, while values above 4.0 indicate strong shear thinning and different gate-freeze behavior. H1100 H should be assigned viscosity ratios by laboratory measurement rather than by family average.

When H1100 H Is Compared with Electroplating and High-Flow ABS Resins

Differences among ABS grades are expressed through melt flow rate, rubber phase design, molecular mass, and comonomer substitution. High-flow injection ABS grades with an MVR above 25 cm³/10 min under ISO 1133-1:2022 fill thin-wall housings at low hydraulic pressure but give lower Charpy notched impact, commonly below 10 kJ/m² for extremely fluid products. Extrusion ABS grades with an MVR below 8 cm³/10 min have higher molecular mass and melt strength, allowing thermoforming sheet with lower sag and higher draw ratios. High-heat ABS grades formulated with alpha-methylstyrene or maleimide derivatives can raise the Vicat softening temperature to 110–125°C and the HDT under 1.8 MPa to 100–110°C, but melt viscosity rises and the melt processing window narrows. Electroplating ABS grades require a narrow polybutadiene particle size distribution near 0.2–0.4 µm and a robust surface grafting layer so that chromic-sulfuric acid etching produces adhesion sites for electroless nickel and copper. Whether H1100 H belongs to a high-heat, high-impact, or high-gloss sub-family is not established by the open literature; therefore, direct lot-specific comparison against these generic families is required before tooling or mold-material selection.

Acrylonitrile content in commercial ABS typically ranges from 15% to 35% by mass, butadiene rubber from 5% to 30%, and styrene as the balance. Higher butadiene raises notched impact but reduces tensile modulus and chemical resistance; higher acrylonitrile improves chemical resistance and heat stability but raises melt viscosity. The exact comonomer balance for H1100 H must be obtained from supplier documentation because it controls the performance balance across these property trade-offs.

The numerical sequence 1100 may refer to a product development series, and the suffix H may indicate a production-line extension or property tilt. Published data for this specific configuration is limited. Industrial users should not infer a property difference from the letter suffix alone; a certificate of analysis providing at least MVR, Charpy notched impact at 23°C, Vicat softening temperature, tensile yield stress, and ash content is the minimum documentation required for comparison. Finished-part qualification per ISO 178:2019 flexural modulus and ISO 527-2:2012 tensile properties should follow a defined sampling plan at the production site.

Application settings for H1100 H are determined by the material sub-family rather than the generic ABS label. ABS resins in this class are used for appliance control panels, vacuum-cleaner housings, electronic enclosures, interior automotive trim components, and extruded sheet for thermoformed luggage shells. The formal suitability of H1100 H for these applications must be supported by the ISO 2580-1:2003 designation block, UL 94 flammability certification, and supplier declaration of regulatory compliance. End-use testing per IEC 62321-3-1:2013 for restricted substances and IEC 60695-11-10:2013 for flammability classification is the responsibility of the molder or converter. The resin cannot be declared food-contact compliant unless the supplier provides specific certification under 21 CFR 177.1020 or an equivalent EU migration-tested regulation; generic ABS is not automatically approved for food-contact or medical devices.

Converters who process H1100 H for painted automotive interior parts should evaluate paint adhesion using a cross-cut test according to ISO 2409:2020 and surface energy measurement after power-wash. ABS surface polarity is moderate; flame or plasma pretreatment can raise surface energy to above 40 mN/m to improve coating adhesion. Published data for this specific configuration is limited, so pretreatment settings must be developed on production line trials rather than transferred from other ABS grades.

For extruded sheet of H1100 H, die temperatures are typically set 5–10°C above the melt temperature to delay freeze-off at the lip. Polished roll temperatures between 80°C and 100°C control surface gloss and sheet orientation. A three-roll stack with roll gap slightly below sheet thickness imposes a negative draw and controls thickness distribution. Thickness tolerance of ±0.05 mm for sheet below 3 mm requires a melt pump and gravimetric feeding. These settings are class-typical and must be re-validated for H1100 H.

Differences between H1100 H and a comparable acrylonitrile-styrene-acrylate product are mainly weatherability. ASA replaces the polybutadiene rubber with acrylic rubber, raising UV resistance and color retention outdoors. ABS H1100 H without UV stabilization will chalk and lose gloss under prolonged outdoor exposure. If exterior weatherability is required, UV-stabilized ABS or ASA should be evaluated according to ISO 4892-2:2013 xenon-arc aging. The H1100 H grade should not be specified for unpainted outdoor service unless supplier data demonstrates the required retention of impact and color.

Melt Filtration, Drying, and Regrind Limits

For sheet extrusion of H1100 H on a 75 mm diameter, 36:1 L/D twin-screw extruder, a melt pump between screw tip and die is often required to reduce pressure pulsation and gauge variation. Melt filtration through a screen pack with a final mesh aperture of 250 µm removes carbonized particles and gel bodies. Filtration pressure should be monitored at a fixed screw speed; a pressure rise above 30% of the clean-screen baseline indicates screen blinding or thermal degradation. For injection molding, back pressure between 0.5 MPa and 1.5 MPa and screw surface speed below 0.3 m/s limit shear heating. Clamp force requirements are set by projected part area and an assumed cavity pressure of 40–70 MPa for ABS; machines between 800 kN and 12,000 kN cover most ABS applications, but H1100 H lot testing should confirm flow length before clamp force is finalized.

Thermal degradation of ABS proceeds through butadiene double-bond oxidation and styrene monomer release at high temperature. In air, thermo-oxidative degradation becomes significant above 230°C; in nitrogen, decomposition onset is typically above 300°C as measured by ISO 11358-1:2022. The practical maximum melt temperature for H1100 H should therefore not exceed 240°C unless the supplier explicitly allows it. Residence time above 5 min at melt temperature increases yellowing, black specks, and reduction of notched impact. Purge shutdowns should use an acrylic-based purge compound, and the barrel should be kept at or below 160°C during extended standby.

Regrind addition at 20 wt% is conventionally accepted for non-appearance ABS parts if the regrind is dry, dust-free, and free of contamination from polypropylene or polycarbonate. Higher regrind ratios must be validated by impact, elongation at break, and color shift. Incompatibilities include direct contact with PVC compounds in hot-runner systems; hydrogen chloride evolved from PVC attacks tool steel and accelerates ABS chain scission. Combinations with amine-based antistatic additives should be tested for discoloration and surface exudation; these additives can promote yellowing at melt temperatures above 230°C.
