PVDF membrane material is coated with PVC resin on high-strength polyester fiber cloth. In order to solve the problem of self-cleaning of PVC membrane material, PVDF (polyvinylidene fluoroacetate resin) is usually coated on PVC coating.
PVDF membrane material is a temporary construction membrane material. Compared with PTFE membrane material, its self-cleaning energy is poor, and it is easy to turn yellow and its self-cleaning performance is declining. It is gradually replaced by high-end membrane materials such as PTFE,
