Acetal (Delrin®, Celcon®)

Acetal is a thermoplastic polymer manufactured by the polymerization of formaldehyde.  Sheets and rods made of this material possess high tensile strength, creep resistance and toughness.  Acetal is used in precision parts requiring high stiffness, low friction and excellent dimensional stability.  Acetal has high abrasion resistance, high heat resistance, good electrical and dielectric properties, and low water absorption.  Many grades are also UV resistant.

Grades: Delrin®, Celcon®
