1. Waterproof and breathable membrane is a polymer organic compound, which is the most widely used polymer material in the world today.
2. The product can basically withstand 80 degrees Celsius, the key is to look at the time. The PE material itself has low temperature resistance. Curling may occur above 100 degrees Celsius, so I don’t know how to do it at 220 degrees Celsius. Its heat resistance is not good. The high temperature resistant polyethylene film can reach 80 degrees in a short time and 40 degrees in a long time, it is easy to curl and degumming.
3. The 50-60°C resistance of the waterproof and breathable membrane is an ordinary high-temperature product. The manufacturer has the technical ability to withstand about 100°C, and the high-temperature resistance time is about 33-40 minutes. Anyway, it's all plastic, and it can't withstand high temperatures of several hundred degrees, and at that high temperature, the plastic melts.
