Polytetrafluoroethylene PTFE wax powder CAS 9002-84-0
Polytetrafluoroethylene PTFE
Polytetrafluoroethylene is a fluorine-containing high-molecular material obtained through the polymerization reaction of tetrafluoroethylene monomers. As the core representative of fluorine polymers, it has become an indispensable key material in industrial and high-end fields. Its molecular chain is composed of stable C-F bonds, with extremely strong chemical inertness. It can withstand the erosion of most chemical media such as strong acids, strong bases, and strong oxidants, and hardly reacts with any substance. It has excellent high-temperature performance, with a long-term usage temperature range of -180℃ to 260℃, and can maintain structural stability even in extreme temperature environments. The surface friction coefficient is extremely low, and it has excellent self-lubrication properties, enabling low-wear operation without the need for additional lubricants.

product superiority
1. Chemical stability and corrosion resistance——It hardly reacts with any chemical substances and can withstand corrosive media such as strong acids, strong bases, and organic solvents.
2. Temperature resistance——Capable of operating stably for a long time within the extreme temperature range of -250℃ to 260℃, featuring both heat resistance and cold resistance, meeting the requirements of extreme working conditions.
3. Surface characteristics——The friction coefficient is extremely low (approximately 0.04), the surface is smooth and highly non-sticky, combining lubricity and non-stick properties. It is widely used in anti-sticking and friction-reducing applications.
4. Electrical insulation property——It is an excellent electrical insulating material with a low dielectric constant and low dielectric loss, suitable for insulation requirements in the field of electronic and electrical products.
application scenarios
1. In the field of chemical process corrosion prevention——It is used to manufacture inner linings and sealing components for reaction vessels, storage tanks, pipelines, and valves, suitable for scenarios involving reactions with corrosive media; it can also be made into corrosion-resistant coatings to cover the surface of equipment to prevent corrosion.
2. Mechanical seal——Produces components such as O-rings, gaskets, piston rings, bearings, etc., and is applied to equipment like engines, hydraulic systems, pumps and valves.
3. Automotive sector——As components such as valve stems, self-sealing parts, shaft seals, gaskets, and fuel hose linings, they ensure the sealing and durability of automotive systems.
