Acetal Copolymer進口共聚甲醛闆棒--潤佳橡塑制品
Acetal Copolymer為(wèi)進口共聚甲醛
共聚甲醛，工程塑膠表面光滑，由於其表面強度高且光滑，POM具有滑動性及耐摩性。POM基本上不會出現張力。共聚型有高耐熱穩定性及化學穩定性(值得特別注意的是抗水解性)
★no micro porosity 無氣孔
★high strength 硬度及剛性
★high rigidity 韌性(到-40℃)
★high thermal stability 尺寸穩定
★good electrical insulation properties 電氣絕緣性佳
★very good sliding properties 滑動性及耐摩性
★high resistance to solvents 抗溶劑腐蝕性能(néng)
★very high resistance to stress cracks抗張裂性能(néng)
☆not resistance to high-concentrated acids不耐強酸和強氧化劑
☆difficult to glue and paint 粘接油漆性差
Acetal Copolymer is preferred to Delrin (DuPont brand Acetal Homopolymer) where centerline porosity is a concern.
Acetal copolymer is produced under several brand names including Celcon, Ultraform & Acetron.
