MODIFIED PTFE SHEET
Modified PTFE is made of PTFE resin with a certain amount of fillers, such as glass fiber, silica, etc., mixed evenly at high speed, molded by molding, and then sintered at high temperature. Has excellent compressibility, recovery and sealing. Its unique properties and high-level characteristics show tightness and torque retention. In the cold flow and the creep characteristics of the material, the shortcomings of the traditional PTFE are overcome, and at the same time it can maintain the bolt load better than the traditional PTFE, which not only improves the durability of the seal, but also reduces the maintenance of the flange.
