POM旭化成HC750

POM旭化成HC750---POM has excellent comprehensive properties, but there are also some shortcomings, 

such as low impact toughness, high notch sensitivity, poor thermal stability and high friction coefficient, 

which greatly limits the application of POM in various fields.

The research on modification of POM has always been the focus of POM industry in the world. 

The research on POM modification has been carried out for more than 40 years in foreign countries, 

with more than 100 brands of modified POM
