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

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.
- Color: Brown
- Temperature Range: -40° to 185° F
- Tensile Strength: 7,690-8,100 psi (Good)
- Impact Strength: 0.7-1 ft.-lbs./in. (Poor)
- Hardness: Rockwell R115-R118 (Hard)
- For Use Outdoors: No
Slippery MDS-Filled Wear-Resistant
Nylon Sheets and Strips
These wear-resistant nylon 6/6 sheets and strips are modified with MDS for a self-lubricating surface that’s more slippery than standard nylon. Use them to machine high-friction parts, such as gears, wear strips, and bearings.
- Color: Black
- Temperature Range: -20° to 220° F
- Tensile Strength: 12,200 psi (Excellent)
- Impact Strength: 1.1 ft.-lbs./in. (Poor)
- Hardness: Rockwell M84-M87 (Hard)
- For Use Outdoors: No
- Specifications Met:
0.015" to 0.02" Thick.: ASTM D6779
0.031" to 0.093" Thick.: ASTM D6779, UL 94HB
1/8" Thick.: ASTM D6779, UL 94V2
Shim Stock
Cut it into custom shapes to fit your application. Sheets come flat packed.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment. Metal shims include a material certificate with traceable lot number and test report.
PTFE plastic shim stock is slippery, so it can be used to reduce friction between parts. It also has excellent chemical resistance.
