About Plastic

These sheets, bars, and strips resist expanding when exposed to heat and moisture, so they can be easily machined to close tolerances. They also have a naturally slippery, wear-resistant surface. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

White sheets, bars, and strips are FDA compliant for contact with food.

Adhesive-back strips are made of Delrin® that is FDA compliant and meets UL 94 HB; however, their adhesive does not meet these specifications.

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. These sheets and strips resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Fabricate them into pump components, gears, and bearings. Delrin® acetal resin is also known as acetal homopolymer.
