As terrible thermal stability, PVC will be decomposed after long duration heating, and release HCL, which will lead to the discolouration of polyvinyl chloride, therefore, the application temperature of flexible PVC film is between 15 ℃ to 55 ℃.
The PVC tube, also named as UPVC pipe, as hard PVC, with high performance for anti-corrosion, well adhesive, hard quality, to avoid the exudation of PVC monomer and additive, PVC tube application temperature is lower than 45 C in water supply system.
