PC/ABS selection should start from part risk

PC/ABS is often chosen as a stronger alternative to ABS, but the correct grade depends on the real engineering risk: heat, impact, flame retardance, shrinkage, assembly stress, surface appearance and long-term aging. A TDS match alone is rarely enough for stable injection molding production.

Impact strength, screw boss cracking risk, snap-fit load, drop impact and assembly stress resistance.

Heat resistance, HDT target, thermal aging and whether PC/ABS is needed instead of standard ABS.

Flame retardant target, UL94 thickness, color, smoke requirement and electrical safety environment.

Injection molding risks including sink marks, shrinkage, gate freeze, packing pressure and cooling imbalance.

Appearance requirements such as gloss, texture, color match, flow marks, weld lines and delayed yellowing risk.

Dimensional stability, wall thickness, rib and boss design, warpage tendency and reinforced PC/ABS options.

FAQ

What is PC/ABS plastic material?

PC/ABS is a polymer blend combining polycarbonate toughness and heat resistance with ABS processability, surface appearance and cost-performance balance. It is widely used for injection molded housings, brackets, electronics, appliance and automotive parts.

When should PC/ABS be selected instead of ABS?

PC/ABS is usually selected when a part needs better heat resistance, impact strength, dimensional stability or stress-cracking resistance than standard ABS can provide, especially in structural or assembly-stressed parts.

Can PC/ABS be flame retardant?

Yes. Flame retardant PC/ABS can be formulated for UL94 targets in electronics, automotive electronics, appliance covers and industrial housings. The formulation depends on wall thickness, color, mechanical targets and certification requirements.

Why do PC/ABS parts show shrinkage or sink marks?

PC/ABS shrinkage and sink marks are usually related to wall thickness, ribs, screw bosses, gate freeze, packing pressure transfer, cooling imbalance and material formulation. Low-shrinkage or reinforced PC/ABS may help in difficult structures.
