65-70℃
The temperature resistance range of PVC film is generally between 65-70℃. Within this temperature range, PVC film can maintain the stability of its physical properties. However, when the temperature exceeds 80℃, the physical properties of PVC will drop significantly, and softening and dimensional changes may occur.
In addition, PVC film will decompose at high temperatures, producing hydrogen chloride gas and other decomposition products, which will not only affect its performance, but may also cause harm to human health. Therefore, when using PVC film, avoid exposing it to high temperature environments to extend its service life and ensure safety.
