Types of PTFE Films
PTFE films come in several varieties, each tailored to meet specific performance requirements.
Specialized PTFE cutting film for PCB boards
Performance index: Polytetrafluoroethylene (PTFE) has the feature of high temperature resistance, the working temperature reaches 260℃. In a wide frequency range of dielectric constant and dielectric loss are very low, and the penetration voltage, bulk resistivity and arc resistance are high, is the ideal material for PCB.
Specialized PTFE film for hydrogen energy batteries
Hydrogen fuel cell stacks consist of multiple monobloc cells laminated in series. The monomer cell is composed of bipolar plates with film electrodes (MEA-catalyst, proton exchange film, carbon paper/carbon cloth). A number of monomers embedded between the seals, the front and rear end plates after compression with a screw fastening tether, that is, constitute a fuel cell stack.
PTFE film for LCD flat panel
Mainly used in the electronics industry, especially in the flat panel display industry, as a kind of consumables are widely used, such as TFT-LCD, COG, SMT, PDP and other processing and production process, its mechanism is to use ACF-Bonding hot press to drive IC with heat and pressure sticking in the glass, Teflon film can play a role in high temperature resistance, impact resistance, etc.
PTFE wire and cable wrapping special film
Application:Wire and cable winding and wrapping, mainly used for electrical cable internal bunching, core to core shielding, outer layer insulation and its sintering.

Ptfe Film Performance Characteristics
High temperature: The use of working temperature of 250 ℃.
Low temperature resistance: Good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain an elongation of 5%.
Corrosion resistance: For most chemicals and solvents, it is inert, resistant to strong acids and alkalis, water and various organic solvents.
Weather resistance: The best aging life in plastics.
High lubrication: The lowest coefficient of friction in solid materials.
Non adhesion: Is the smallest surface tension in solid materials, does not adhere to any substance.
Non-toxic: With physiological inertia, as artificial blood vessels and organs long-term implantation in the body without adverse reactions.
Electrical insulation: Can resist 1500 volts high voltage.

Application of PTFE Film
Application in electrical and electronic
The inherent low loss and small dielectric constant of polytetrafluoroethylene film (PTFE) material enable it to be made into enameled wires for micro-motors, thermocouples, control devices, capacitors, radio insulation pads, insulated cables, motors and transformers, etc. Using the characteristics of fluorine plastics that cause polar charge deviation under high temperature and high pressure, microphones, speakers, robot parts, etc.
Application of anti-corrosion performance
Polytetrafluoroethylene film (PTFE) material has become the main corrosion resistant material in petroleum, chemical, textile and other industries because of its excellent corrosion resistance. Its specific applications include: conveying pipes, exhaust pipes, steam pipes for conveying corrosive gases, high-pressure oil pipes for steel rolling mills, Senior high school and low-pressure pipes for hydraulic systems and cold-pressure systems, rectification towers, heat exchangers, kettles, towers, and tanks Lining, valves and other chemical equipment.
Application of low friction performance in load
Because the coefficient of friction of the PTFE film is the lowest among the known solid materials. Its specific uses include bearings for chemical equipment, papermaking machinery, agricultural machinery, used as piston rings, machine tool guide rails, guide rings; in civil construction engineering is widely used as a bridge, tunnel, steel roof truss, large chemical pipelines, storage tank support slider, and used as a bridge support and bridge swivel.
Application in Medical and Pharmaceutical
The expanded polytetrafluoroethylene membrane (PTFE) material is purely inert, has very strong biocompatibility, does not cause body rejection, has no physiological side effects on the human body, can be sterilized by any method, and has a microporous structure, which can be used in a variety of rehabilitation solutions, including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for blood vessels, heart, general surgery and orthopedics.
Application of anti-sticking performance
Polytetrafluoroethylene film (PTFE) material has the smallest surface tension in solid materials, does not adhere to any substance, and also has excellent characteristics of high and low temperature resistance, so that it has a wide range of applications such as non-stick pan anti-sticking. The anti-sticking process mainly includes two kinds: the PTFE parts or sheets are installed on the substrate, and the PTFE coating or the lacquer cloth combined with the glass is shrunk on the substrate.
