AKON sells a variety of materials. Standard clear 20 mil and 13 oz, 18 oz, and 22 oz vinyl materials are rated for 60 °C (140 °F). However, if your application involves temperatures around 60 °C, the curtains can, and eventually will, fail.
The best comparison is an engine running with your foot fully on the pedal. You are operating it at its maximum capability, and it will eventually fail. The same is true for using curtains at their maximum temperature rating. They will work, but there is no way to guarantee how long. The material becomes very soft and grommets can pull out, or tears can occur. If you need industrial high temperature rated curtains then view our line of heat resistant industrial curtains.
