1. Teflon film, also known as PTFE film, Teflon film, f4 film, is made of suspended PTFE resin by molding, sintering, cooling into a blank, and then turning, calendering.
The film turned into a non-oriented film, and the non-oriented film is calendered into an oriented film. The unoriented film was calendered 1.1-1.8 times to the semi-oriented film. Teflon film is used for capacitor dielectric, wire insulation, electrical instrument insulation, gasket. It has high crystallinity, molecular orientation tightly arranged, small porosity, and thus the Teflon film has a greater increase.
PTFE film is divided into PTFE color film, PTFE activation film and F46 film.
Teflon color film is made of suspended polytetrafluoroethylene resin by adding a certain amount of colorant after molding, sintering to make blanks and then turning, calendering to make red, green, blue, yellow, purple, brown, black, Orange, white and other 13 colors of Teflon oriented or non-oriented color film. Although PTFE color film is added with a certain amount of colorant, it still has good electrical insulation, which is suitable for insulation and classification identification of wires, cables and electrical devices. Although PTFE color film is added with a certain amount of colorant, it still has good electrical insulation, which is suitable for insulation and classification identification of wires, cables and electrical devices.
PTFE activation film is a film made of PTFE film, filled film and color film, and then treated by surface activation. The products are added with pigments, glass fiber, carbon fiber, graphite, bronze powder and other fillers, and the performance is further improved after activation treatment. It can be compounded with rubber, metal, etc., and can also make special tape to meet the design requirements. Widely used in light industry, military, aerospace, oil and other fields.
F4 thin film has the most significant advantages of anti voltage strength and breakdown voltage. Used for capacitor dielectric, wire insulation, electrical instrument insulation, sealing gasket. Polytetrafluoroethylene turning film calender by hot roll rolling orientation of a kind of oriented film, it has high crystallinity, molecular orientation tightly arranged, the void ratio is small, so the polytetrafluoroethylene film has a greater increase, especially the resistance voltage strength is more obvious.

The difference between 2. nylon and PTFE
Polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion sintering, drying, high temperature sintering, shaping and other processes made of special pipe. Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, PTFE, Plastic King, English is Teflon, which is widely used in machinery, electronic appliances, automobiles, aerospace, chemicals, computers, Electric heating, military, communications and other important scientific and technological industries, such as micro transformers.
Nylon is an outstanding American scientist Carrothers (Carothers) and under the leadership of a scientific research team developed, is the world's first synthetic fiber. The emergence of nylon makes textiles look new, its synthesis is a major breakthrough in the synthetic fiber industry, but also an important milestone in polymer chemistry.
The density of PTFE is generally greater than 2, while the density of nylon is about 1.2. The density of PTFE is relatively dense, high temperature resistance and hardness will be relatively good, while nylon tube is relatively soft, high temperature resistance is worse than PTFE tube, but because it is relatively soft, it can adapt to more terrain. In terms of price, PTFE tube is slightly more expensive than nylon tube.
PTFE Product Features
1. High chemical stability: It can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong bases, strong oxidants, reducing agents and various organic solvents. Ideal for high purity chemical feeding use.
2. Low friction coefficient: The friction coefficient is generally only 0.04, which is a very excellent self-lubricating material, and the friction coefficient does not change with temperature. 3
3. Excellent anti-adhesion, 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 properties: 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.
Part of the tube has high transparency and can easily observe the internal fluid condition.
