Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
Silicone rubber is much better than ordinary rubber in heat resistance. It can be used almost always at 150 degrees without performance changes. It can be used continuously for 10000 hours at 200 degrees, and can be used for a period of time at 350 degrees. The utility model is widely used for occasions requiring heat resistance, a thermos bottle sealing ring and a heat-resistant handle of a pressure cooker ring.
At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used as lubrication, but also become an ideal coating to clean the inner layer of the water pipe.Most of the PTFE material contains plasticizers.
Polytetrafluoroethylene (Polytetrafluoroethylene), abbreviated as "PTFE", is commonly referred to as "nonstick coating" or "easy to clean material". The material has the properties of acid fast, alkali resistance and various organic solvents. It is almost insoluble in all solvents.
