Specifications

Product name:CPVC resin J-700
Type:J-700
Packaging detail:25kg/bag
PVC Raw matrial: C-62 from Qilu Petrochemical of SINOPEC

The CPVC resin is made by chlorination modification of PVC resin and is one advanced engineering material. This product is white or canary loose grain or powder with no smell, odorless and innocuity. After chlorination, the irregularity of molecular bond of the PVC resin and the polarity of molecular chain increase, the dissolvability and chemical stability of the resin also increase, and accordingly improve the heat resistance and resist the corrosion of acid, caustic, salt and oxidant etc. In addition, it improve the mechanical performance of numerical heat distortion temperature and chlorine content increases from 56.7% to 63-69% and Vicat softening temperature from 72-82 °C to 90-125 °C ; its highest service temperature can reach 110 °C and long-term service temperature can reach 95 °C . Accordingly, CPVC is one kind of advanced engineering plastic with vast foreground. 

 

 Storage and transportation

    This product shall be stored in the dry and ventilated warehouse with stack height nor more than 10 bags and avoid solarization and damp. Its transportation must use clean conveyance with covering against solarization, drench and heated. It is innocuous un-dangerous cargo.
