Additional Specifications |
Because these naturally slippery, wear-resistant rods and discs resist expanding when exposed to heat and moisture, they can be easily machined to close tolerances. They are a good choice for parts that require precision, such as gears, bushings, and bearings. Delrin® acetal resin is also known as acetal homopolymer; it is stronger and stiffer than acetal copolymer.
