Four Characteristic of PVC

  •  

    1.The raw material granule is mixed by PVC  resin- oatmeal and P83 nitrile rubber and plastic ,so  its shock resistance and elongation at break than PVC,the cost performance is very good.

  •  

    2.Physical performance:55-85A,temperature range is from -30°C to 90°C.
