POM Sheets plastic is a semi crystalline thermoplastic with high mechanical strength and rigidity.

Delrin Machined Parts

POLESTAR® Polyacetal / Delrin rods offer a unique combination of properties not available with metals or other plastics.

Due to its low moisture absorption rate, Acetal’s physical properties remain constant in every environment, resulting in an ideally suited and stable product for close tolerance mechanical parts and electrical insulators of Delrin Machined Parts.

A distinction is made between acetal homopolymers (POM-H – mainly manufactured from DuPont Delrin®) and acetal copolymers (POM-C) in regard to their properties. Due to its higher crystallinity, the properties of POM H include a slightly higher density, hardness and strength. POM C material, however, has higher chemical resistance and a lower melting point than POM H.
