PTFE Tube Aging resistance

Line is the life of the current, the transmission of information transmission channel, but because a part of the line is buried in the ground, affected by the environment, will cause erosion damage on the leakage situation, have an impact on life.

Now on the line construction, the general will choose polytetrafluoroethylene push pipe to protect the line, because the PTFE tube has a very excellent chemical chaos, resistance to all strong acid, alkali, strong oxygen Chemical agent, and a variety of organic solvents do not play a role. Under normal pressure can be used for a long time -180 ℃ ~ 250 ℃, and heat and no water, so it is an excellent electrical insulation material. Also has excellent

Good anti-aging, non-sticky and non-flammable. So tetrafluoroethylene tube is the ideal line protection "shield".

In addition, PTFE pressure tube is widely used in mechanical, chemical, aviation, electrical and electronic, defense industry, cutting-edge technology, medical and health and electrical insulation and other fields.

Polytetrafluoroethylene heating pipe is in the seamless metal pipe (carbon steel pipe, titanium tube, stainless steel tube, brass) into the electric wire, open field filled with good thermal conductivity and insulation of magnesium oxide powder

Shrinkage made, and then processed into the user needs a variety of shapes. It has a simple structure, high thermal efficiency, good mechanical strength, the harsh environment has a good adaptability. It can be used for a variety of liquids and Acid and alkali salt heating, but also to adapt to the melting point of low melting metal heating (lead, zinc, tin, babbitt), the user can provide special specifications for the design and processing.

Including U type, L type, W type and combination type;

Combined with all the strong erosion of chemical medium heating, the working temperature is not greater than 100 ℃;

Teflon heating tube is widely used in chemical, electroplating pickling and other erosion processing industry;

Teflon heating tube load is very low, high insulation resistance;

Teflon heating tube in line with GB GB / T2379-93;

Can be customized user requirements for design.

Polytetrafluoroethylene film is molded by pressing the cylindrical billet, the machine after cutting film and then rolled from. According to the different treatment methods can be divided into oriented film, semi-oriented film and non-directional film three, the current PTFE film products are porous membrane, microfiltration membrane, color film and so on.

Its color film used in the glorious distinction between the electrical instrumentation or wire insulation, is a new type of integrated performance excellent C-class insulation material, is the radio industry, the flight

Air industry and cutting-edge science and technology in one of the important materials indispensable. Polytetrafluoroethylene film is generally used in suspension polymerization of polytetrafluoroethylene resin, requiring particle diameter below 150μm. Paint must be Need to have good heat resistance (> 400 ℃), fine particles, strong coloring, the chemical reagents and other requirements.

Teflon film production process:

PTFE resin, pigment → mixing → molding → sintering → cooling → turning non-oriented film → calendering semi-oriented film
