POM-H is a homopolymer acetal that is manufactured by Ensinger (using white Delrin® resin) under the tradename 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 TECAFORM AD natural acetal one of the most versatile engineering materials available today.
