DELRIN® 500AF Blend

POM H with ptfe

Delrin 500AF brown is very similar to Delrin 100AF in that this material performs exceedingly well in bearing or low friction applications that also require good strength and dimensional stability characteristics. Containing PTFE fibers, this modified acetal homopolymer material has a slightly more crystaline structure than Delrin 100AF, so therefore exhibits slightly higher strength and modulus as well as improved machining characteristics. It is designed for applications requiring low wear and, or low friction against steel, itself or other plastics. It is perfect forplastic bushing or bearing applications requiring a low coefficient of friction.
