An economical alternative to Delrin® acetal resin, these acetal copolymer sheets and bars offer the same naturally slippery surface and similar wear resistance. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Use them for parts that require precision, such as gears, bearings, and bushings.

Antistatic Wear-Resistant Easy-to-Machine Acetal Sheets

Color: Off-White
Temperature Range: -20° to 180° F
Tensile Strength: 5,000-6,400 psi (Good)
Impact Strength: 1.5 ft.-lbs./in. (Poor)
Hardness: Rockwell R110 (Hard)
For Use Outdoors: No
Specifications Met: UL 94 HB

In addition to having a naturally slippery, wear-resistant surface, these sheets prevent the buildup of static charges. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. They’re also excellent electrical insulators. Use them for conveyor components and other moving parts where static is a concern.
