About Plastic

Deburring and Edge-Rounding Media
for Aluminum, Brass, and Soft Metals

Good for light material removal.

Impact-Resistant Plastic Pellets

Absorbing impact without cracking or breaking, these plastic pellets are molded into parts that endure bumps, scrapes, and falls.

Wear-Resistant Plastic Pellets

With a low coefficient of friction, these pellets won't wear away from abrasion that’s often caused by contact with moving parts. Melt and mold them into desired shapes.

Moisture-Resistant Plastic Pellets

These pellets resist swelling when exposed to water, making them suitable for use in wet environments. Melt and mold them into desired shapes.

Wear-Resistant Easy-to-Machine
Delrin® Acetal Resin Balls

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Polypropylene Balls

Because this polypropylene resists swelling when exposed to water, it’s often fabricated into containers and parts for laboratory equipment.

Wear-Resistant Nylon Balls

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Moisture-Resistant Polyethylene (HDPE) Balls

Practically nonabsorbent, HDPE won't swell when exposed to moisture. It is denser and more rigid than LDPE, plus it's more chemical resistant.

Chemical-Resistant Slippery PTFE Balls

Known for its naturally slippery surface, PTFE surpasses most plastics when it comes to chemical resistance and performance in extreme temperatures.

High-Strength Wear-Resistant Torlon PAI Balls

Among the strongest plastic materials we offer, Torlon PAI has a slippery surface that resists wear. Use it to make high-friction compressor parts, bearings, and seals.

Scratch- and UV-Resistant Acrylic Balls

This extruded acrylic offers similar performance as cast acrylic at a lower cost.

Clear Impact-Resistant Polycarbonate Balls

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.
