U型槽模具制作原料有聚丙烯pp原料和ABS树脂两种。PP是由丙烯聚合而制得的一种热塑性树脂,是一种半结晶性材料,它比PE要更坚硬并且有更高的熔点。

There are two kinds of raw materials for making U-groove mould: PP raw material and ABS resin. PP is a www.yangquanbanjia.cnwww.lizhumuju.cnwww.shuozhoubanjia.cnwww.xinzhoubanjia.com.cnwww.jin

chengbanjia.cnwww.shaiwang.org.cnthermoplastic resin prepared by polymerization of propylene. It is a semi-crystalline material. It is harder and has higher melting point than PE.

聚丙烯具有很好的可塑性,可溶性和韧性。ABS树脂是微黄色固体,有一定的韧性,它抗酸、碱、盐的腐蚀能力比较强,也可在一定程度上耐受有机溶剂溶解.其中还有钢模具，水泥以及混凝土
Polypropylene has good plasticity, solubility and toughness. ABS resin is a yellowish solid with certain toughness. It has strong corrosion resistance to acid, alkali and salt. It can also tolerate dissolution of organic solvents to a certain extent. Among them, steel mould, cement and concrete are also included.
