  1. Teflon bellows

  Teflon bellows name: PTFE bellows, F4 bellows, PTFE bellows, PTFE bellows, Teflon bellows, Teflon bellows, Teflon bellows, Teflon bellows , Teflon bellows, Teflon bellows, plastic king bellows

  Teflon bellows color:

  Common color: milky white tube

  Unusual colors: yellow, brown, green, blue, red

  Teflon corrugated pipe use

  Can be used as tubular reactor and exchanger in special occasions

  Can be used as feeding and discharging pipes for tank trucks, storage tanks, containers and reactors

  Can be used to replace graphite, ceramic, glass and other pipes with lower mechanical strength

  It can be used for pipe misalignment connection or to balance pipe displacement and dimensional changes caused by weather or other reasons or to eliminate high-frequency mechanical vibration

  Teflon bellows characteristics

  Operating temperature: -200 degrees to 260 degrees

  Ease of processing: can flanging

  High transparency: the lowest refractive index among all plastics

  Aging resistance: can be exposed to ozone and sunlight for a long time without aging

  Corrosion resistance: able to withstand the action of all strong acids, strong oxidants, strong reducing agents and various organic solvents except for molten alkali metals, fluorinated media and those above 300°

  The surface is not sticky: the known solid material head cannot stick to the surface

  Non-combustibility: Will not burn in the air and meet the strict requirements for fire protection

  Non-toxic: non-toxic, tasteless, physiologically inert, without any harm to people and the environment

  Two, Teflon fep tube

  The abbreviation of Teflon is PTFE, the Chinese name is polytetrafluoroethylene, and the English name is Poly tetra fluoro ethylene ptfe emulsion is a kind of polytetrafluoroethylene polymer chemical material, it is widely used in packaging, electronic and electrical, chemical energy, resistant Corrosive materials, Teflon high-performance special coatings are fluorine coatings with polytetrafluoroethylene as the matrix resin. The English name is Teflon. Because of the pronunciation, it is usually called Teflon, Teflon, and Teflon. , Teflon, Teflon, etc. (all are the transliterations of Teflon).

  The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: FEP, is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The melting point of FEP crystal is 304°C and the density is 2.15g/CC (grams/cubic centimeter).

  The commonly used color of PTFE is milky white, and the less commonly used color is translucent and colorful. At present, no transparent PTFE product has been invented in the world. The performance of FEP is similar to that of PTFE. There are two differences. FEP has a temperature resistance of 200 degrees and PTFE has a temperature of 260 degrees. FEP replaces PTFE without the defect of transparency. If you want a transparent tube with a temperature of 260 degrees, you can use PFA. .

  This material has excellent wear resistance, low friction coefficient, and can be used from low temperature to 392F. The material can be made into granular products for extrusion and molding, used as powder for fluidized bed and electrostatic coating, and can also be made into water dispersion. Semi-finished products include films and plates. Rod and single fiber.

  Its main purpose is to make linings for pipes and chemical equipment, surface layers of drums, and various wires and cables, such as aircraft hook wires, booster cables, alarm cables, flat cables and oil well logging cables. FEP film has been used as a thin coating for solar collectors.

  Polyperfluoroethylene propylene FEP or F46 is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 15%. It is a modified material of polytetrafluoroethylene.

  Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor is Dongguan Dandi Insulation Material Co., Ltd. Fluoroplastic Material Factory, established in 1998, specializes in FEP, PFA, PTFE and other fluoroplastic pipes R&D, production and sales of rod, sheet and film products and other insulating materials. The company has a senior R&D team with international standards and a production line of fluorine plastic products imported from abroad. Some fluoroplastic products have passed ISO9001, SGS, FDA certification, and have been fully affirmed by domestic and foreign cooperative customers such as Huawei, Foxconn, Midea, ZTE, Intel, and AirTAC. The main products of the company are: ①Tubes: Ptfe tube, Fep tube, Pfa tube, Pvdf tube; ②Heat shrinkable tube: Ptfe heat shrinkable tube, Fep heat shrinkable tube, Pfa heat shrinkable tube, Pvdf heat shrinkable tube; ③Plate rod Membrane: Ptfe board and rod film, Fep board and rod film, Pfa board and rod film, Pvdf board and rod film; ④Insulation materials: silica gel, PE, PVC, UPE, etc.; ⑤Special category: PFA imported connector, spiral tube, spring tube , Rotary cut tube, welding rod, tee, straight-through, gasket, joint, taper rod, flared tube, sealing tube, braided tube, bellows, etc. At the same time, fluorine plastic products of various specifications can be customized and processed according to customer requirements.
