摘要
聚丙烯材料是一种优异的通用塑料，其机械强度高，接近工程塑料。在通常情况不溶于绝大多数溶剂，易于生产。三型聚丙烯（PPR）是以新型无规聚丙烯为原料，经挤出成型制作的塑料管材。
The polypropylene is good general plastic material. It＇s strength is very high, which approaches the strength of engineering plastic. Generally it is not dissolved to so many solvents. And its production process is simple. The PPR pipe is plastic pipe which the crude material is new type polypropylene.
