  1. What is the temperature resistance of PTFE sheet?

  There are two types of PTFE plates: molded plates and turned plates. The molded plates are made of polytetrafluoroethylene resin molded by molding at room temperature, and then sintered and cooled. The turning board is made of PTFE resin by pressing, sintering, and peeling.

  Features of PTFE sheet: PTFE sheet has excellent chemical stability, can withstand all strong acids, strong alkalis, strong oxidants, and does not interact with various organic solvents. PTFE has a wide operating temperature range. It can be used for a long time at -180℃~250℃ under normal pressure. After 1000h of treatment at 250℃, its mechanical properties will change little. PTFE has a very low friction factor, is a good anti-friction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running when used to make bearings. Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility.

  Characteristics of PTFE sheet:

  1. The operating temperature range is very wide (from -200 degrees to +260 degrees Celsius)

  2. Basically have corrosion resistance to all chemical substances except some fluorides and alkaline metal liquids.

  3. Excellent mechanical properties including aging resistance, especially for bending and swing applications.

  4. Outstanding flame retardancy (in accordance with ASTM-D635 and D470 test procedures, it is designated as a flame retardant material in the air.

  5. Excellent insulation characteristics (regardless of its frequency and temperature)

  6. The water absorption rate is extremely low, and it has a series of unique properties such as self-lubricity and non-stickiness.

  PTFE sheets are widely used in industries such as nuclear energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, food and other industries as high and low temperature resistant, corrosion resistant materials, insulating materials, and anti-stick coatings.

  Second, the price of PTFE pipe

  PTFE tube, scientific name PTFE tube (referred to as F4 tube, PTFE tube) is the use of high-quality plunger extruded tube, using special processing technology to make the steel tube and plastic tube tightly combined, can withstand positive pressure 1.6 Mpa, negative pressure: 77Kpa; it can be used normally within -60℃~+260℃, with reliable and excellent corrosion resistance. Transporting highly corrosive gases and liquids at high temperatures cannot be replaced by other pipelines. It is widely used in machinery, chemical industry, aviation, electrical and electronics, defense industry, cutting-edge technology, medical and health, electrical insulation and other fields.

Because PTFE is non-polar, heat-resistant and does not absorb water, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility.
