Water supply have to endure a certain degree of pressure, usually large selection of molecular weight, good mechanical properties of PE resins, such as HDPE resin.
给水管必须承受一定的压力，通常要选用分子量大、机械性能较好的PE树脂，如HDPE树脂。
The results show that: the kind of PE influences the graft rate and MFR of the product directly, the sequence of grafting ability is LDPE>LLDPE>HDPE;
实验结果表明：产物的接枝率和熔体流动速率（MFR）变化与聚乙烯的种类有直接关系，接枝性能从优到差的顺序为： LDPE> LLDPE> HDPE；
