PTFE products are generally referred to as "non-stick coatings". It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. PTFE cnc machining is resistant to acid, alkali and various organic solvents. It is almost insoluble in all solvents. PTFE cnc is also resistant to high and low temperatures, up to -180°C to 260°C. Its friction coefficient is extremely low, and the friction with steel can reach 0.04, which is close to rolling friction and can be used for lubrication.
