PVDF is a semi-crystalline polymer with (—CH2—CF2—) repeating units. It has high mechanical strength, good chemical resistance and thermal stability, and excellent aging resistance.
In order to solve the self-cleaning problem of PVC film material, PVDF (polyvinylidene fluoride resin) is usually coated on the PVC coating, which is called PVDF Membrane material.
