PP的意思是聚丙烯,PPR全名叫做三型无规共聚聚丙烯,PPR跟PP的重要差别如下
1:资料,PPR在改性工艺里参加了约5-10%的PE资料,以增添PPR的柔韧性
2:分子构造差别
3:机能方面PPR占优,PPR要比PP更柔韧,下降了高温脆性的缺点。不外同样的,PPR的钢性较PP也有所下降。 当初市道上大多应用的都是PPR水管了,PP管基础上用不着.
1:PPR ADDS about 5-10% PE material to the modification process to increase the flexibility of PPR
2: Different Molecular Structure
3: PPR is superior in performance, PPR is more flexible than PP, reducing the vulnerability of low temperature Brittleness. Similarly, however, PPR is less rigid than PP. Now most of the use of the market is the PPR pipe, PP pipe basic need.
