PTFE material has the smallest surface tension and inertness among solid materials and does not adhere to any substance. PTFE material has the lowest coefficient of friction, excellent self-lubrication, and also has excellent resistance to high and low temperatures, which makes it very widely used in applications such as the manufacture of non-stick pans for anti-adhesive. In addition, such as the application of PTFE material in the roller or set in other parts, used as a guide wheel, PTFE rollers, can let the film, paper, textiles, etc. quickly through. Can also be made into thin sheets such as chemical fiber molding sheet, textile lubrication block installed in the loom to prevent a variety of silk thread adhesion and made of PTFE shaped parts for mechanical equipment, to prevent glue and other bonding difficult to remove. And the use of PTFE coating and These applications are the use of PTFE material friction coefficient is small, non-stick characteristics, the performance of the product through the tension is reduced to a minimum, attached to the dirt is also easy to clean.
PTFE wear-resistant composites are made of PTFE resin as a matrix and have good wear resistance by adding organic or inorganic wear-reducing components and anti-wear reinforcing components. The wear-resistant composites with polymer matrix have a series of excellent characteristics such as self-lubrication, wear resistance, corrosion resistance, vibration absorption, noise reduction, low relative density, strength enhancement and easy processing, etc. So they are being used more and more widely as alternatives or substitutes for other materials. We also note that the usual use of inorganic materials have good performance, the price is also low, can increase the hardness of the material, wear resistance, dimensional stability, etc. But some inorganic materials will also damage the couple when friction. And organic filling materials such as polyphenylene resin, polyimide, wear resistance, creep resistance, etc. Because it is a soft material, will not damage the couple, but the price is expensive, so it should be based on Therefore, the filler products should be selected according to the use environment and requirements of the material, and the reasonable cost to bear. Polytetrafluoroethylene has the highest temperature range of plastic use space, the lowest surface energy, non-stick, corrosion resistance, insulation, non-aging and a unique position in the field of friction lubrication wear, I believe that the future polytetrafluoroethylene material will be better in quality.
