Radici Compounds AC90W

AC90W is an acetal copolymer with a viscosity suitable for general purpose injection molding, containing a finely dispersed stabilizer system. This composition provides excellent protection against the effects of prolonged exposure to outdoor weathering or other sources of ultra-violet light. It is internally lubricated for ease of mold release. The natural color of the base resin is not affected, so that AC90W can be made available in a full range of colors.

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. Acetal copolymer 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.

Versatility and reliability make acetal copolymer the cost effective material of choice for a wide range of applications in all major end-use categories.

The use of AC90W should be considered for applications where resistance to the effects of UV exposure is required, but where the use of a black pigmented compound is not acceptable.
