Som frygtelig termisk stabilitet nedbrydes PVC efter opvarmning i lang tid og frigøres HCL, hvilket vil føre til misfarvning af polyvinylchlorid, derfor er anvendelsestemperaturen for fleksibel PVC-film mellem 15℃til 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.
