Product Summary

PCABS-WH3120A is an unfilled, general-purpose PC/ABS alloy supplied as pellets for injection molding. The published WanHan data sheet gives a notched Izod impact of 45 kJ/m² (ISO 180), a melt index of 18 g/10 min (ISO 1133) and a heat-deflection temperature of 102 °C (ISO 75), placing it in the mid-range of balanced impact, flow and heat performance for molded housings.

The grade is published as UL 94 HB at 1.6 mm. That rating defines its use boundary: it is intended for HB applications, and it should not be substituted for a V-0 flame-retardant grade without exact-grade evidence. Published values come from WanHan's general-purpose PC/ABS table, and test conditions plus finished-part results should be confirmed before approval.

Key Features

• Balanced stiffness and toughness: tensile strength 45 MPa and flexural strength 95 MPa with flexural modulus 2,720 MPa (ISO 178), while elongation at break reaches 54% (ISO 527) — rigid housing walls without the brittle failure mode of a highly filled compound.
• 45 kJ/m² notched Izod impact (ISO 180): impact margin for parts that face handling, snap-fits and assembly loads.
• 102 °C heat-deflection temperature (ISO 75): suits enclosures positioned near internal heat sources.
• Molding data published: melt index 18 g/10 min (ISO 1133), density 1.18 g/cm³ and mold shrinkage 0.6% (ISO 2577) give a starting basis for cavity layout and tolerance planning.
• Flame rating stated up front: UL 94 HB at 1.6 mm — if the specification calls for V-0, a separate flame-retardant grade must be quoted.
• Unfilled alloy system: no filler is listed for this model in the published data.

Technical Specifications

Test conditions and finished-part results should be confirmed before grade approval. Published values describe the material, not a molded part.

Models and Options

One model is published for this general-purpose grade: PCABS-WH3120A. WanHan's wider compound range covers PA6, PA66, PP, PBT, PC, PC/ABS, ABS, PA11, PA12, PET and PPS formulations, and flame-retardant PC/ABS options must be quoted and evidenced as separate grades. Grade selection should follow wall thickness, part geometry, service temperature and the required flame rating.

Materials and Structure

The compound is a PC/ABS alloy — polycarbonate blended with acrylonitrile-butadiene-styrene — with no filler listed for this model. It is delivered as compounded pellets produced on WanHan's line, which covers incoming material inspection, controlled feeding, extrusion, water cooling, pelletizing, multi-instrument testing and automatic weighing and packaging.

Applications

Published application guidance for this grade includes TV enclosures, sockets, power switches and other molded housings. Each application remains subject to application-specific validation: final part performance, flame rating and regulatory compliance must be confirmed for the exact grade and part design.

Customization

WanHan lists material selection, custom formulation development, glass-fiber reinforcement, heat stabilization, flame-retardant modification, toughness modification, color matching, sample evaluation and injection-molding processing guidance among its technical services. For PCABS-WH3120A, confirm target color, part geometry and required flame rating; where V-0 is required, a different grade must be quoted.

Quality System Certifications

• ISO 9001:2015 Quality Management System — certificate 27326Q00154R153, valid through 2029-05-29.
• ISO 14001:2015 Environmental Management System — certificate 27326E00087R153, valid through 2029-05-29.
• ISO 45001:2018 Occupational Health and Safety Management System — certificate 27326S00077R153, valid through 2029-05-29.

All three certificates are issued by Zhongren Certification Co., Ltd. and cover the design and production of modified plastic pellets at company level. They do not certify the performance or regulatory compliance of an individual product grade.
