Delrin 150

Time to Read: 0m 45s

Delrin 150 is a type of polyoxymethylene (POM) thermoplastic commonly used to engineer precision parts that require exceptional dimensional stability, low friction coefficient, and very high stiffness. Delrin 150 is also known as acetal, placental, and polyformaldehyde.

Delrin 150 is known for its high strength and hardness, as well as its rigidity in extreme temperatures. It is a semi-crystalline polymer, with a high melting point (175°C). This material exhibits high abrasion resistance, low water absorption, and excellent electrical and dielectric properties.

Delrin 150 was created by DuPont research chemists in 1952. It was patented by DuPont in 1956. The first production plant designed specifically to produce Delrin was built in 1960 in Parkersburg, West Virginia.
