CPVC advantage:
1.Using temperature can reach 93-110℃,the highest using temperature can be 110℃,long time used temperature can be 95℃。
2.CPVC is a new engineering plastic material made of modified PVC resin.
This resin is white or light yellow odorless, tasteless and nontoxic loose granule or powder
3.Chlorination of PVC resin irregularity of molecular link 、polarity、solubility and chemical stability are added
