The polytetrafluoroethylene PTFE material has minimal surface tension and inertness in a solid material and does not adhere to anything. PTFE has the lowest friction
Coefficient, excellent self-lubricating performance and excellent high and low temperature resistance, widely used in non-stick pan anti-sticking.
In addition, if the PTFE material is coated on the sleeve on the roller or other parts, it is used as a guide wheel, a PTFE roller, which can quickly pass through and spin the film, paper, fabric, etc.
The film of fabric A lubricating block, etc. is installed on the loom to prevent the adhesion of various wires and to manufacture PTFE molded parts for mechanical equipment to prevent adhesives and like difficult to remove;
The varnish coated with PTFE coating and glass is heat-shrinkable and covered on the substrate. These applications are characterized by the low coefficient of friction and non-stick of the PTFE material, which means that when
The tension is reduced to the minimum when the product passes through, and the attached dirt is also easy to clean.
Compared with other polymers, PTFE has unique advantages, but it also has some defects, such as poor machinability, large linear expansion coefficient, poor creep resistance, easy cold flow, resistance
Poor grinding. Lack of molding and secondary processing difficulties limit its application. At present, both at home and abroad concerned about the study of PTFE is looking for an appropriate method to modify
improve its performance to a certain extent, and expand its scope of application. In order to strengthen the application research and development of PTFE, we need to focus on the research and development of new high
Can PTFE composite material. PTFE manufacturers are also constantly improving and applying.

Polytetrafluoroethylene (PTFE) wear-resistant composite material is based on PTFE resin, which has good wear resistance by adding organic or inorganic anti-wear components and anti-wear reinforcement components. Polymer
Base wear-resistant composite materials have a series of excellent properties such as self-lubricating, wear-resistant, corrosion-resistant, shock absorption, noise reduction, relative density, increased strength, easy processing, etc., and can be used as a substitute for other
Materials. Products or alternative products have been used more and more widely.
We also noticed that the commonly used inorganic materials have good performance and low price, which can improve the hardness, wear resistance, dimensional stability, etc. of the material, but some inorganic materials also
May damage the double parts; organic filling materials such as polyphenylene, polyimide, etc., wear resistance, creep resistance, etc. are very good, because it is a soft substance, it will not damage
Bad double parts, but it is expensive, so it should be based on the material. The use of the environment and requirements and the resulting cost of reasonable choice of filler products.
PTFE has the highest temperature range in plastics, the lowest surface energy, non-stick, corrosion resistance, insulation, non-aging and a unique position in the field of friction lubrication. Many studies at home and abroad
Everyone has Teflon. The modification technology is studied and discussed, and it is believed that the quality of PTFE materials will be better improved in the future.
