How can we improve?

22,085 Products

Raw Materials

Plastic

A lightweight alternative to metal and glass

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Kevlar

Super tough for protection against prolonged wear and abrasion

Additives and Fillers
