        问: in use is PPR powder material injection molding is tough property 太差. how can increase tough property 呢?

        答: according to issues, analysis below/following 几点:

        1, PPR本身 tough property very good.

        2, powder material is one-time injection molding, material separation has fracture, property increase, tough property decline is 肯定.

        3, PPR is Common plastics in more most 便宜 一 types, this belt/tape issues, issues is is reduce cost, in raw materials made 时候会 a large amount of add filling agent slip powder what, this 就导致 tough property decline, one-time processing also combined, rear impact resistant property can speed decline. issues is is Raw Materials this 么便宜, also has has necessary pelletizing, has that pelletizing 钱呢, also is more 买点一手 raw materials, this can and material use impact resistant property decline very more.

        4, PPR in injection molding upper product quality generally requirements high, therefore waste product 不会太 more, add upper material 枝, 你 二次 material more, use 行.

        5, therefore, selection has 三:

        第一 is 掺 二次 material use.

        第二 is selection tough property strong/high Raw Materials (this ratio again pelletizing 便宜).

        第三就 is pelletizing.
