1. PTFE sheet supplier
PTFE board is a kind of engineering plastic with excellent comprehensive performance, and its excellent performance is unmatched by other plastics.
The advantages are as follows:
1. A wide range of high and low temperature applications. It can be used for a long time in the range of -180℃~250℃;
2. Excellent chemical stability. Corrosive media such as strong acids, strong alkalis, and strong oxidants cannot have any effect on it;
3. High electrical insulation. Unaffected by environmental conditions and frequency, it is a Class C insulating material;
Fourth, it has good lubricity. After adding different kinds of filler materials, it can enhance the hardness and wear resistance. It is an ideal material for oil-free lubrication;
5. Good weather resistance. Exposure to the atmosphere for many years, the surface and its various properties remain unchanged.
Teflon board characteristics:
The maximum width of the PTFE board is 2.5 meters, and it is made of suspended polytetrafluoroethylene resin by molding. According to the production process, it is divided into two types: molded board and turned board. Among the known plastics, PTFE has the best chemical resistance and dielectric properties. It is not aging, non-sticky, and can be used at a temperature of -180℃-+260℃ under no load. It can be used in known solids. It has a lower coefficient of friction in the material.
Uses of PTFE board:
Process and manufacture gaskets, seals, lining partitions, scrapers, guide rails, electrical insulators used under various frequencies, and bridge support sliders.

Second, which Ptfe board rod film is cheap?
Polytetrafluoroethylene is also known as (F4, PTFE, plastic king, tetrafluoroethylene, Teflon, Teflon.)
PTFE has some special properties:
Excellent corrosion resistance-able to withstand the action of all strong acids (including aqua regia), strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and sodium hydroxide above 300°C .
Very strong insulation resistance---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.
Excellent resistance to high and low temperature --- little effect on temperature, wide temperature range, applicable temperature-190℃ and +260℃.
Unique self-lubricating property---with a small coefficient of friction in plastics, it is an ideal oil-free lubricating material.
Prominent surface non-stickiness-known solid materials can not adhere to the surface, it is a solid material with low surface energy.
Excellent resistance to atmospheric aging---radiation resistance and low permeability---exposed to the atmosphere for a long time, the surface and performance remain unchanged.
Valuable non-combustibility-the oxygen limit index is below 90.
In addition to the wide range of uses of PTFE extruded pipes, the use of ptfe plate rod film is also very wide.

3. Shenzhen Rotary Cutting Tube Manufacturers
Teflon casing is a special pipe made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, and shaping.
After the production of the Teflon extruded tube is completed, the rotary cut tube is additionally cut into a rotary cut tube by a machine.
Teflon rotary cutting tubes are widely used in important technology industries such as machinery, electronic appliances, automobiles, aerospace, chemicals, computers, electric heating, military, and communications, such as micro-transformers.

Rotary tube characteristics:
1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.
2. Low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature.
3. Excellent anti-sticking property, and the inner wall of the tube is not easy to adhere to colloids and chemicals.
4. Excellent aging resistance, can be used outdoors for a long time.
5. Excellent electrical insulation performance: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.
