Carbon Teflon PTFE Sheet (sheet) and Rod (bar) filled with other materials such as graphite, bronze, glass and carbon. Carbon Teflon (PTFE) is a solid chemical compound that is used as a non-stick coating for pots, pans and other cooking utensils, because Teflon carbon has the lowest coefficient of friction compared to other solid materials. Apart from being made for cooking utensils, PTFE coating is also non-reactive so it is often used for chemical pipe coatings that are reactive and corrosive. Main Features Teflon Carbon High strength fatigue strength and rigidity Creep resistance noise reduction Seal stability to withstand leakage.
