Acetal Copolymer Static Dissipative
Acetal Copolymer Static Dissipative Overview
What is the Material: Acetal Copolymer Static Dissipative is a semi-crystalline material and it is a modified acetal copolymer filled with an anti-static additive.
Key Material Features: This material is beneficial in applications requiring reduced buildup of electric charges, while maintaining many properties of other acetal copolymer materials including high mechanical strength, rigidity, wear resistance, low moisture absorption, and dimensional stability.
Other Considerations: The addition of the anti-static additive can impact the strength and hardness of the material, depending on the application. Nylon materials typically perform better than acetal materials in abrasive wear applications.
