PVC
Polyvinyl chloride, PVC, has excellent strength-to-weight ratio and superior flame resistance, coupled with its low cost, make it the material of choice for the most demanding applications. PVC is an amorphous thermoplastic material with excellent chemical resistance and dielectric properties, good tensile, flexural and mechanical strength, low moisture absorption, exceptional dimensional stability and good flammability characteristics.
PVC sheet rod has excellent corrosion resistance and weather resistance. The working temp is 0℃~60℃. and the forming temperatures of 120℃. The physical properties of PVC can be readily altered by the addition of plasticizers, impact modifiers and other ingredients to develop and enhance specific properties.
PVC applications are almost unlimited. PVC is the most widely used member of the vinyl family and it is excellent when used for corrosion-resistant tanks, ducts, fume hoods and pipe. PVC is ideal for self-supporting tanks, fabricated parts, tank linings and spacers. PVC is not UV stabilized and not a FDA approved materials.
