Polytetrafluoroethylene (PTFE):
The polymer compound formed by polymerization of tetrafluoroethylene has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistance materials in the world today, except for molten alkali metals, chlorine trifluoride, and pentafluoride. In addition to chlorine and liquid chlorine, it can withstand all other chemicals. It will not change when it is boiled in aqua regia. It is widely used in various occasions that require resistance to acids, alkalis and organic solvents. It has sealing properties, high lubrication and non-stick properties, electrical insulation and good anti-aging ability, excellent temperature resistance (can work for a long time at a temperature of positive 260 ℃ to negative 180 ℃). Teflon itself is not toxic to humans. The operating temperature is -180～260℃, allowing rapid cooling and heating, or alternate operation of cooling and heating. Pressure -0.1～6.4Mpa.

Expanded PTFE:
It is a new type of medical polymer material, made of PTFE resin through special processing methods such as stretching. It is white, full of elasticity and flexibility, and has a network structure formed by the connection of fine fibers. These fine fibers form numerous pores, so that the expanded PTFE can be bent arbitrarily (over 360°), has good blood compatibility, and is resistant to biological aging. Used in the manufacture of medical products such as artificial blood vessels and heart patches. From a medical point of view, it is the most ideal substitute for biological tissues. Due to its good biocompatibility and unique microporous structure, it is non-toxic, non-carcinogenic, non-sensitizing and other side effects, and human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissues.

PTFE production method:
Teflon base type: Teflon PTFE: Teflon FEP: Teflon PFA: Teflon ETFE: After Teflon coating, it has the following characteristics: 1, non-stickiness, 2, heat resistance, 3 , Sliding, 4. Humidity resistance, 5. Wear resistance, 6. Corrosion resistance, chemical properties, insulation, high and low temperature resistance, self-lubricating, non-sticky surface, non-combustibility.
Application of PTFE (Polytetrafluoroethylene):
1. Polytetrafluoroethylene (PTFE) can be used in construction, anti-corrosion function, electronic and electrical, medical treatment, etc.
2. PTFE film is an aspirational insulating material for the manufacture of capacitors, radio insulating gaskets, insulated cables, motors and transformers, and is also one of the indispensable materials for industrial electronic components such as aerospace;
3. Using fluoroplastics to generate polar charges under high temperature and high pressure, which violates appearance characteristics, can be used to manufacture microphones, speakers, parts on robots, etc.; use its low refractive index characteristics to manufacture optical fibers.
Uses of E-ptfe (ePTFE):
1. High performance fabric
GORE™ film is light, durable, waterproof and windproof, and can be processed into a variety of fabrics with different water permeability or "breathability" grades. The result: a unique high-performance fabric that is both comfortable and protective.
2. Medical implants
Because expanded polytetrafluoroethylene (ePTFE) is purely inert, it 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 plastic surgery , So that both doctors and patients can benefit from it. Our medical products can coordinate with the body's own organization and restore its normal functions.

3. Fluoropolymer fiber
Gore expanded polytetrafluoroethylene (ePTFE) fiber has the characteristics of high strength, low shrinkage, anti-wear and other characteristics, and has strong anti-ultraviolet performance, so as to ensure its good stability and integrity in extreme environments sex. This fiber has a wide range of uses. It can be woven, woven, braided or sewn into a variety of fabrics, including compression packaging, sewing threads, construction fabrics, dental floss, and so on.
4. Gaskets and sealants
Expanded polytetrafluoroethylene (ePTFE) has good chemical resistance, anti-wear properties and strong high temperature and low temperature resistance, which is very suitable for the transportation and sealing of industrial liquids. GORE's gaskets and sealing products, including flat type, thin belt type and on-site forming sealant, are suitable for flanges of any size or specification.
