Delrin® 150 is a homopolymer acetal that is manufactured by Ensinger (using  Delrin® USA LLC resin) and sold under the trade name TECAFORM AD natural. This homopolymer acetal has exceptional sliding characteristics and good wear resistance properties. In comparison to POM-C, POM-H has a slightly higher density, hardness and strength due to its higher crystallinity. In addition, POM-H has good electrical insulating properties, as well as exceptional machining characteristics, making Ensinger's extruded Delrin® 150 natural acetal one of the most versatile engineering materials available today. Delrin® is registered trademark of Delrin USA LLC.
