产品说明

AC90T is an acetal copolymer formulation, impact modified to improve practical toughness and ductility. It exhibits a viscosity suitable for a wide range of injection molding applications and is lubricated for ease of mold release.

Acetal copolymer is a highly crystalline engineering thermoplastic based on trioxane, polymerized with a comonomer to provide exceptional thermal stability both in processing and for molded parts which may be exposed to high temperature environments. AC90T exhibits the characteristics of a true engineering material; predictability of performance in a wide range of environments and for long periods of time. Performance characteristics combine excellent strength, rigidity and toughness, a unique resilience, outstanding static and dynamic fatigue resistance, natural lubricity and resistance to a very wide range of solvents, oils, greases and chemicals, including strong alkalis. Extremely low moisture absorption results in excellent dimensional stability, and therefore an ability to hold precision tolerances in parts exposed to a wide range of humidity.

AC90T can be considered for applications where these fundamental benefits of acetal copolymer are required, combined with improved toughness and ductility.
