PTFE hose with Over Cover Layer, Our coating materials include but are not limited to Pu, PVC, glass fiber, TPU, PVDF, silica gel, polyester, cotton thread of various colors, aramid fiber, etc. The main function of various cladding layers is to protect the stainless steel braided layer, increase the service life of the pipe, and enable the pipe to be used in more application scenarios. Among them, glass fiber has the function of heat insulation (thermal insulation). Aramid fiber can enhance the working pressure of the pipe and play the role of thermal insulation. Silica gel coating plays a role of wear resistance and thermal insulation, which can protect stainless steel braided layer to a certain extent. It can improve the wear resistance of pipes while playing the role of thermal insulation. It is very suitable for the use scenarios where the requirements of thermal insulation and wear resistance are required. In addition, stainless steel braided PTFE tube coating material also has a variety of colors, can be ordered according to your needs.
