TECAFORM AH SD natural

electrically active POM-C

Ensinger manufactures natural acetal (POM-C) material modified by the addition of a special anti static agent. The product is sold under the trade name TECAFORM AH SD natural. The addition of this anti static agent produces a defined degree of conductivity in the anti static range. However, the addition of the anti static agent can compromise the strength and hardness of the material depending on the application. TECAFORM AH SD natural is a white acetal and offers good wear resistance, high chemical resistance, and has high toughness and strength. Furthermore, this special anti-static POM-C white acetal has exceptional electrical conductivity, which makes it a perfect material for products and applications in the electronics industry. ​
