The high temperature resistance of PVC leather depends on factors such as its type, additives, processing temperature and use environment.
The heat resistance temperature of ordinary PVC leather is about 60-80℃. This means that, under normal circumstances, ordinary PVC leather can be used for a long time at 60 degrees without obvious problems. If the temperature exceeds 100 degrees, occasional short-term use is acceptable, but if it is in such a high temperature environment for a long time, the performance of PVC leather may be affected.
The heat resistance temperature of modified PVC leather can reach 100-130℃. This type of PVC leather is usually improved by adding additives such as stabilizers, lubricants and fillers to improve its heat resistance. These additives can not only prevent PVC from decomposing at high temperatures, but also reduce melt viscosity, improve processability, and increase hardness and heat resistance at the same time.
The high temperature resistance of PVC leather is also affected by the processing temperature and the use environment. The higher the processing temperature, the lower the heat resistance of PVC. If PVC leather is used for a long time in a high temperature environment, its heat resistance will also decrease.
In summary, the high temperature resistance of ordinary PVC leather is between 60-80℃, while the high temperature resistance of modified PVC leather can reach 100-130℃. When using PVC leather, you should pay attention to its high temperature resistance, avoid using it in a high temperature environment, and pay attention to controlling the processing temperature to extend its service life.
