Is PVC hose heat resistant

PVC (polyvinyl chloride) hoses are very common in daily life and industrial applications, and their heat resistance is one of the important indicators to evaluate their use scenarios. In general, PVC hoses have a certain heat resistance, but this characteristic is limited by its formulation and production process. Ordinary PVC hose under conventional conditions of use (such as room temperature to about 60°C), stable performance, suitable for conveying water, air and other media.

However, when faced with higher temperatures, PVC hoses may gradually soften, deform, and even release harmful substances, affecting their safety and life. Therefore, for applications that need to withstand higher temperatures, such as hot water circulation, steam delivery, etc., high temperature resistant PVC hoses with special formulations are usually selected, or hoses made of other high temperature resistant materials such as silicone, fluorine rubber, etc.

In short, PVC hose has good heat resistance in a specific temperature range, but it may no longer be suitable when it exceeds its tolerance limit. In the selection, it is necessary to carefully evaluate its heat resistance and safety according to the specific use environment and requirements.
