ACETAL COPOLYMER SD
Tecaform Static Dissipative (SD) is a natural copolymer acetal with static dissipative characteristics. Its comparatively low surface and volume resistivities, excellent bearing and wear properties, and toughness make Tecaform SD an ideal material for moving components experiencing friction or parts subject to fluid flow contact.
