POM raksturojums

POM is a tough and elastic material, which has good creep resistance, geometric stability and impact resistance even at low temperatures. POM has both homopolymer and copolymer materials. Homopolymer materials have good ductility and fatigue strength, but are not easy to process. Copolymer materials have good thermal stability, chemical stability and are easy to process. Both homopolymer materials and copolymer materials are crystalline materials and not easy to absorb water. The high crystallinity of POM results in a very high shrinkage, which can be as high as 2 percent ~3.5 percent . There are different shrinkage rates for different reinforced materials.
