POM copolymer is an injection molding type of plastic with excellent flow properties, making it ideal for producing very thin-walled precision molded parts. It allows for processing at lower temperatures and shorter cycle times, reducing production time and costs. This material is suitable for applications with lower mechanical requirements. It offers good resistance to solvents, fuel, and strong alkalis, as well as hydrolysis resistance. Additionally, it exhibits high resistance to thermal and oxidative degradation. With the addition of UV additives, it can be used for a wide range of applications, particularly for very thin-walled precision molded parts that require processing at reduced temperatures and shorter cycle times.
