Technical Data
产品说明
AC25 is an acetal copolymer with a viscosity suitable for extrusion applications, or for injection molding of thicker wall-section parts requiring optimum toughness.
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.
AC25 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.
AC25 should be considered for extrusion application such as profile, tubing, rod or slab where it's higher melt strength will be an advantage. AC25 is also selected for injection molding applications where the higher viscosity can help improve packing of thicker section parts, and also realize best practical toughness.
