POM ELS

POM – Polyacetal

POM ELS

Polyacetal (POM-C) is modified with added carbon to make it electrically conductive. The material is extremely strong and hard, and it has excellent properties related to resistance to wear, chemicals, UV radiation and weather. Because of its excellent wear-resistance properties, it is ideal for slider applications. We deliver POM-ELS as plastic sheets and bars.
