POM-C sheet is a semicrystalline thermoplastic and is characterized by a low coefficient of friction and good wear properties, and good wear properties,unaffect-ed by wet environments.POM plate offers good resistance to a wide range of chemicals including many solvents. A Delrin plate provides high strength and stiff-ness coupled with easy machineability. AHD is also noted for its high me-chanical strength,heat resistance and good antifriction properties. A For parts which need to be dimensionally stable even exposed to humidity or wet envi-ronments, POM-C offers better hot water,ther- mal and chemical resistance than POM-H.
When it comes to chemical resistance, POM sheets excel. It has high resistance to solvents, fuels, oils and many other chemicals, making it ideal for components that come into contact with these substances. POM sheet also has high dimensional stability, which means it retains its shape and dimensions even under extreme temperature conditions.
Another advantage of POM sheets is their low moisture absorption. Unlike many other plastics, POM has a very low tendency to absorb moisture, which affects its mechanical and electrical properties. This makes it suitable for use in humid environments where hygroscopicity is a concern.

One of the outstanding features of POM sheet is its excellent sliding properties. It has a low coefficient of friction, which means it slides easily over other surfaces without much resistance. This makes it a popular choice for applications requiring smooth, friction-free motion, such as gears, bearings and sliding parts.
POM sheets also have high wear resistance, which is critical in applications involving repetitive mechanical movements. It can withstand long-term wear and friction, making it durable. In addition, POM is not prone to creep, which means it retains its shape and stability even under long-term stress.
Machinability is another advantage of POM sheets. It can be easily machined and manufactured using traditional manufacturing processes such as milling, turning and drilling. This allows for the easy production of complex and precise parts. POM sheet also has good electrical and dielectric properties, making it suitable for electrical insulation applications.
