Acetal (Copolymer) is a tough, stable thermoplastic offering a unique combination of properties which include high modulus of elasticity, high strength, rigidity and dimensional stability. Copolymer acetals can accept reinforcement much better than the homopolymer.

This non-carbon filled acetal contains a permanantly static dissapative material designed for use where electrical discharge in operation is a problem. Additives such as carbon fibers, stainless steel fibers are all used to modify the electrical resistivity of acetal resin so that static charge can dissipate safety through the material.

Homopolymer acetal is most commonly recognized as Delrin, resins that are currently made by the DuPont Company under the trade name Delrin®AF. Homopolymers have slightly higher mechanical and thermal properties than Copolymers.

PTFE fibers uniformly dispersed in Delrin®AF Acetal resin offers better wear characteristics than unfilled Delrin®AF Acetal, particularly for use in moving parts in which low friction and long wear life are important.

15% or 20% glass fiber filler provides much greater mechanical properties over unfilled acetals.
