FAQs about Acetal and Delrin:
-
Are Acetal and Delrin the same? While Acetal and Delrin share many similar characteristics, they are not identical. There are significant differences that can impact your choice of material. Acetal refers to a family of thermoplastics known as PolyOxyMethylene (POM). It is available in two types of resins: Copolymer acetal (POM-C) and Homopolymer acetal (POM-H), also known as Delrin®. POM-C offers better dimensional stability due to its lower level of crystallinity, while Delrin® provides greater stiffness, higher flexural modulus at room and elevated temperatures, slightly higher tensile and impact strength at room temperatures, and a lower coefficient of friction due to its hardness.
-
