A gear is a mechanical element that continuously meshes with gears on the rim to transmit motion and power. In modern industrial products, gears are the most common and important functional components, none of them.

Expanded PTFE sheet is made of 100% Expanded PTFE material by special process.It has the characteristics of high flexibility, compressibility,no aging,self-lubrication and high tensile strength.It is an excellent sealing material and can be used for sealing in various harsh occasions.It is especially suitable for various pipe end face connections or flange face seals with fittings.

​Due to the defects in corrosion resistance of materials such as rubber, glass, and metal alloys, it is difficult to meet the harsh environment of coexistence of temperature, pressure and chemical medium, and the resulting losses are quite alarming.
