Highlights at a glance

PVC hot water bags are preferred over rubber due to their lower odor, better feel, and enhanced brightness. While PVC's thermal deformation temperature is around 80°C, it remains stable below 100°C, making it safe for hot water use. Proper additives and processes significantly improve the thermal stability of qualified PVC products. Explore recommended PVC resins for optimal performance.

Generally, the thermal deformation temperature of PVC is 80 â„ƒ. If it exceeds 110 â„ƒ, it will become very unstable, and the decomposition will be accelerated, and it will melt when it reaches 150-160 â„ƒ. But why are there PVC hot water bags? Because PVC hot water bags have less taste than rubber hot water bags, and they have better brightness and feel better than rubber. So it has advantages over rubber hot water bag. The temperature of boiling water is about 100 degrees Celsius, which has no effect on the PVC material after production. In general, try not to use just boiling water because it is too hot to burn the skin. Now qualified PVC hot water is made by adding additives such as composite heat stabilizer and matching with appropriate process, and the thermal stability of its products will be greatly improved.
