Filled polytetrafluoroethylene composites are used more and more widely in hydraulic and pneumatic seals. They can be used alone to make hydraulic cylinders, cylinder guide support rings, dynamic and static seal rings and gaskets; PTFE composites can pass The secondary machining process produces the PTFE composite guide belt, which solves the processing problem of the large-diameter hydraulic cylinder and the guide ring of the cylinder. It can be applied to large cylinders with a diameter of more than 1 meter, which greatly reduces the manufacturing cost of such seals. In particular, PTFE bronze composite guide tapes have been widely used in the hydraulic and pneumatic sealing industry.

China PTFE TFM Axial Shaft Radial Ring Manufacturer filled PTFE composite materials can also be combined with other engineering plastics and rubber-plastic elastomers to produce combined seals of various shapes and sizes, such as: cylinder cylinder seals, Glüh ring, Sterling, and Special seals, special seals, buffer rings, rotating glyph rings, pan plug seals, V-shaped seals, etc. Reasonable selection of PTFE composite materials and other rubber and plastic materials for matching, can be applied to different working conditions, such as: bronze powder-PTFE composite material is suitable for reciprocating motion of medium and high pressure hydraulic system; glass fiber graphite-PTFE composite material can For hydraulic pneumatic reciprocating or rotary motion; carbon fiber-PTFE composite is more suitable for rotary motion, high temperature and high pressure water or steam, oil-free lubrication, and can also be used for reciprocating motion. In the process of designing hydraulic and pneumatic machinery, more types of PTFE composite seals can be made according to the design requirements of hydraulic and pneumatic systems, combined with the properties of filled polytetrafluoroethylene composites.

The filled polytetrafluoroethylene composite material has excellent physical and mechanical properties, excellent friction and wear properties, and can be used for secondary mechanical processing of the polytetrafluoroethylene composite material according to actual working conditions and reasonable use of the filler type and ratio. Effectively combined with other rubber and plastic materials, it produces hydraulic and pneumatic combination seals with excellent comprehensive performance: high pressure resistance, wear resistance, low friction resistance, reliable dynamic and static sealing performance and long service life. It is widely used in hydraulic and pneumatic sealing industry.
