PTFE pipe is made of suspension polymerization PTFE resin by plunger extrusion processing. Among the known plastics, polytetrafluoroethylene has the best chemical resistance and dielectric properties. Polytetrafluoroethylene
Ene braided packing is a good dynamic sealing material, which is woven from expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis and no hard change.
Excellent performance. Gasket seals and lubricating materials used in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used at various frequencies.
Features of 1. PTFE pipe
1. The appearance of the product should be uniform in texture.
2. The appearance is smooth and smooth.
3. No hair, crack, bubble, delamination or mechanical scratch is allowed.
4. A small amount of foreign impurities is allowed.

Use of 2. PTFE pipe
1. Used for wire insulation sheath in the temperature range of -180 ℃ ~ 260 ℃.
2. Corrosive fluid medium pipeline.
3. Insulation parts used at various high frequencies.

Five application fields of 3. PTFE
PTFE has a wide range of applications. It can be used in medical equipment, printing, papermaking, fiber industry, chemical industry, food industry, household appliances, plastics, rubber industry, electronics, automobiles
industry, etc.
1. PTFE is used in the medical device industry: in order not to allow medicine to directly contact with the device that transmits medicine, or to reduce surface tension or conductivity, we can paint certified
Used in medicine or health care equipment on the polytetrafluoroethylene to achieve the purpose. Such as: needle tube, dripper, medical equipment parts, etc.
2, PTFE used in the chemical industry: PTFE coating has significant heat stability, in a short period of time can be resistant to 320°C, generally in -190 ℃ ~ 260 ℃ can be used continuously, it is in
No embrittlement at cooling temperature and no melting at high temperature. At the same time, PTFE coating has a strong physiological inertness, in addition to individual media, almost no chemical corrosion, can protect
Parts are protected from any kind of chemical corrosion.
3, PTFE for household appliances: PTFE spraying can also be used for a variety of household appliances, in order to reduce the accumulation of food, grease, dirt, to achieve easy cleaning and improve raw products
qualitative purpose. Such as the production of ice, frying pan, coffee pot, scones, a variety of pastry molds.
4. PTFE is used in the plastic box rubber industry: PTFE can be used to manufacture molds for epoxy resin and phenolic resin products, and appropriate PTFE coatings can be selected based on its economic benefits
Spraying on the surface of the mold to solve the problem of product sticking to the mold and not easy to demould, thus prolonging the use time of the mold. Such as soles, rubber gloves, tire forming mold, etc.
5. PTFE is used in the electronics and automotive industry: PTFE is the most widely used in the electronics and automotive industry, and the substrate is different from the size and material. PTFE coating, resin can be used in
One hundred thousand grade clean room spray PTFE to meet industrial requirements. Such as: conductive valve, mobile phone board, valve, weather strip, hybrid throttle valve, bearing retainer, etc.
