Material · ABS Molding

ABS plastic.
Workhorse polymer.
Tough & moldable.

ABS (Acrylonitrile Butadiene Styrene) injection molding for consumer products, electronics housings, automotive interior. Excellent processing, good aesthetics, moderate strength.

01 · Key principles

Key principles.

Material profile

Tough thermoplastic

ABS = acrylonitrile (rigidity) + butadiene (toughness) + styrene (gloss). Versatile workhorse.

Properties

UTS 40 MPa, density 1.05

Good impact strength, dimensional stability, easy to machine and finish.

Processing

Injection 220-260°C

Easy to mold. Wide processing window. Pre-dry 80°C × 4 h required.

Applications

Consumer, electronics

LEGO bricks, automotive trim, electronics housings, appliance parts.

Variants

PC-ABS blend

Polycarbonate-ABS blend offers higher strength + heat resistance.

Cost

Mid-priced

~$3-4/kg material. Mid-range for engineering plastic.

FAQ

Why is ABS so popular?

Best balance of cost, processability, mechanical properties, and aesthetic. Easily painted, plated, glued, machined. Mainstream consumer plastic.

UV stability?

Standard ABS yellows in UV. Use UV-stabilized grade or apply UV-blocking paint for outdoor.

Heat resistance?

Service temperature up to ~80°C. Above that, consider PC-ABS, PC, or higher-grade.

Chemical resistance?

Good vs alcohols, oils, dilute acids. Poor vs ketones, esters, aromatic solvents.

Color options?

Wide range — pre-colored compound or in-machine masterbatch. Pantone matching standard.

Production volumes?

Injection economical above 1000 pcs/year. Aluminum tooling 5-10K shots, steel tool 100K+.
