POM resin (POM), also known as acetal, polyacetal and polyformaldehyde, is a high-strength, low-friction engineering thermoplastic. Good resistance to abrasion in both wet and dry environments. An easy-to-work material, an ideal choice for the fabrication of parts with complex machining requirements and demanding dimensions.
At room temperature, Pom material has outstanding advantages in hardness and toughness. As a material with good working performance, ability to work continuously in high temperature environment.
