PTFE Bushings PTFE Spacer Gasket Flat Washer

Polytetrafluoroethylene PTFE F4 is one of the best corrosion resistant materials in the world today, so it is called "the king of plastics". it can be used in any kind of chemical medium for a long time, and its emergence has solved many problems in China's chemical, petroleum, pharmaceutical and other fields. pad Coils, gaskets, PTFE seals, gaskets and sealing washers are made of suspension polymerized PTFE resin molding. gather Compared with other plastics, tetrafluoroethylene has excellent chemical corrosion resistance and temperature resistance. It has been widely used as a sealing material and filling material. It has high chemical stability and excellent resistance to chemical corrosion, such as strong acid, strong alkali, strong oxidant, etc Heat resistance, cold resistance and friction resistance. The temperature range for long-term use is - 190~260 ° C. It also has excellent electrical insulation and is not affected by temperature And frequency. In addition, it has the characteristics of non-stick, non-absorbent and non-burning. Suspension resin is generally molded and sintered The bar, plate or other profiles can be further processed by planer, drilling, milling and other machining methods. The bar can be made into directional film by turning and drawing.

 

PTFE MATERIAL PROPERTY

 

The insulation is not affected by the environment and frequency, the volume resistance can reach 1018 ohm · cm, the dielectric loss is small, and the breakdown voltage is high.

 

The impact of high and low temperature resistance on temperature is small, and the temperature range is wide, and the applicable temperature is - 190~260 ℃.

 

Self-lubricating property has the smallest friction coefficient among plastics, and is an ideal oil-free lubricating material.

 

Solid materials with known surface non-stickiness cannot adhere to the surface, and are solid materials with minimum surface energy.

 

Resistance to atmospheric aging, radiation resistance and low permeability. The surface and properties remain unchanged after long-term exposure to the atmosphere.

 

It is non-toxic and has physiological inertia, and has no adverse reaction after long-term implantation as artificial blood vessel and organ.

 

In addition to molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluoride, the chemical corrosion resistance is resistant to all other chemicals, and does not change when boiled in aqua regia. It is widely used in various occasions requiring resistance to acid, alkali and organic solvents.

 

Excellent electrical performance is an ideal Class C insulation material. A thick layer of newspaper can block 1500V high voltage: smoother than ice.

 

PTFE APPLICATION

 

ptfe sheet , ptfe tube, ptfe rod and ptfe customized parts , such as ptfe Seals, ptfe bushings,ptfe back-up rings, ptfe guides, ptfe pads, ptfe plugs, ptfe rollers, ptfe v-packing rings, ptfe spacers, ptfe o-rings, ptfe wear rings, ptfe washers and ptfe gaskets, ptfe valve etc.

 

PTFE's mechanical properties are low compared to other plastics, But its mechanical properies acna be enhanced by adding fillers such as galss firbers, carbon, graphite, molybdenum disulphide and bronze etc.
