The high temperature resistance of PSU pepper balls is relatively high among all pepper balls. When the general working environment temperature is below 180 degrees, PSU pepper balls can run at high speed without lubricating oil, and there will be no deformation. However, some workplaces often need higher temperatures, so it is necessary to modify and enhance PSU pepper balls.

After PSU modification and enhancement, the temperature resistance can be above 220 degrees, and the most prominent performance is that it is installed in an automobile engine. PSU pepper balls are not only resistant to high temperature, but also resistant to oil, which is impossible for plastic balls made of other materials. PSU pepper balls are mainly modified by adding a certain proportion of glass fiber into the material, and the highest proportion can reach about 30%. The temperature resistance of PSU pepper balls with glass fiber is greatly improved and the strength is increased. At present, the mainstream engine manufacturers.
