Wear-Resistant Easy-to-Machine Delrin®
Acetal Resin Sheets, Bars, and Strips

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 Sheets and Strips

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 Sheets

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 Sheets and Bars

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

Wear-Resistant Easy-to-Machine Acetal Film

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

Antistatic Wear-Resistant
Easy-to-Machine Acetal Sheets

This material prevents the buildup of static charges.

Multipurpose Plastic Selector Packs

Packs include one 2” square of ABS, Delrin® acetal, LDPE, HDPE, UHMW, nylon, cast nylon, polyester, polystyrene, Rexolite polystyrene, and Noryl PPO.

Machine Key Stock

Cut this stock to length to create the machine key you need. Straight keys, with a square or rectangular cross section, are the most common type of key. Install in a keyway to transmit torque from shafts to gears and other components.
