1 What is the difference of homopolymer and copolymer of POM?
Homopolymer POM
melting point 175~183℃, crystallization 75~85%, tensile strength 70MPa, elongation at break: 40%, molding shrinkage 2.0~2.5%.
Copolymerized POM
melting point 160~165℃, crystallization 70~75%, tensile strength 62MPa, elongation at break: 60%, molding shrinkage 2.5~3.0%.
2 What is characteristics of POM?
High heat distortion temperature
Good low temperature resistance
Excellent insulation performance
Good oil resistance
Low water absorption
