About Plastic

Wear-Resistant Easy-to-Machine
Delrin® Acetal Resin Rods and Discs

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

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

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

Slippery Wear-Resistant Easy-to-Machine
Delrin® Acetal AF Resin Rods and Discs

The addition of PTFE provides a more slippery, wear-resistant surface than standard Delrin® acetal resin. It’s commonly fabricated into pump components, gears, and bearings.

Rigid Glass-Filled Wear-Resistant
Easy-to-Machine Delrin® Acetal Resin Rods

A glass-fiber filler gives this material increased rigidity over standard Delrin® acetal resin. Use it to machine manifolds, impellers, and other parts that require rigidity.

Wear-Resistant Easy-to-Machine Acetal Copolymer

Wear-Resistant Easy-to-Machine Acetal Rods and Discs

An economical alternative to Delrin® acetal resin, this acetal copolymer offers similar wear resistance.

Wear-Resistant Easy-to-Machine Acetal Tubes

An economical alternative to Delrin® acetal resin, this acetal copolymer offers similar wear resistance.

Antistatic Wear-Resistant Easy-to-Machine Acetal Rods

This material prevents the buildup of static charges.

Slippery Wear-Resistant
Easy-to-Machine Acetal Copolymer

A silicone additive gives this material a self-lubricating surface that reduces friction and extends the life of your parts.

Washers

Water- and Steam-Resistant Plastic Washers

Low moisture absorption and good heat resistance make these washers suitable for wet and harsh environments.

Metric Water- and Steam-Resistant Plastic Washers

Low moisture absorption and good heat resistance make these metric washers suitable for wet and harsh environments.

Spring Lock Washers for Plastic Screws

Designed for use with plastic screws, these acetal washers are good electrical insulators. They are excellent for use under water and in rotating assemblies.
