Heat Resistance, Cold Resistance, Corrosion Resistance, Wear Resistance Polytetrafluoroethylene Powder PTFE

Overview of Polytetrafluoroethylene Powder PTFE Powder

Polytetrafluoroethylene (Poly tetrafluoroethylene, abbreviated as PTFE), frequently called “Plastic King,” is a high molecular polymer acquired by polymerizing tetrafluoroethylene as a monomer. White waxy, clear, outstanding cold and heat resistance, can be made use of for a very long time at -180 ~ 260ºC. This product has the features of acid and alkali resistance and resistance to different natural solvents and is nearly insoluble in all solvents. At the same time, polytetrafluoroethylene has the qualities of high-temperature resistance. Its rubbing coefficient is significantly reduced to ensure that it can be utilized for lubrication. It has additionally ended up being an excellent layer for simple cleansing of the internal layer of pipes.
  Product Performance of Polytetrafluoroethylene Powder PTFE Powder

Along with having the ability to respond with liquified antacids steels, it is not struck by any material, even if it is steamed in hydrofluoric acid, aqua regia or fuming sulfuric acid, salt hydroxide; it will certainly not transform.
2. White, odorless, unappetizing, safe powder, frequently called “Plastic King.” Has superb chemical security, deterioration resistance, securing, high lubricating non-stick homes, electric insulation and excellent aging resistance. High-temperature resistance, functioning temperature level of approximately 250 ℃. Low-temperature resistance and great mechanical sturdiness at reduced temperature levels can preserve 5% prolongation even if the temperature level goes down to -196 ℃. Rust is immune, inert to the majority of chemicals and solvents, immune to solid acids and antacids, water and numerous natural solvents. Excellent climate resistance and the best-aging life in plastics. High lubrication is the most affordable coefficient of rubbing amongst strong products. Non-adhesion is one of the smallest surface area stresses of strong products and does not stick to any compounds. Safe, from a physical standpoint, inert, lasting implantation right into the body as fabricated capillary and body organs without negative responses.

 How is Polytetrafluoroethylene Powder PTFE Powder Produced?

1. Preparation of monomeric tetrafluoroethylene
   In industry, chloroform is used as a raw material. Chloroform is fluorinated with anhydrous hydrofluoric acid, the response temperature level is above 65ºC, antimony pentachloride is utilized as a driver, and ultimately, tetrafluoroethylene is prepared by the thermal fracturing technique. Tetrafluoroethylene can also be obtained by reacting zinc with tetrafluorodichloroethane at high temperatures.
2. Preparation of PTFE
   In an stainless steel polymerization kettle, using water as a medium, potassium persulfate as initiator, ammonium perfluorocarboxylate as a dispersant, fluorocarbon as a stabilizer, tetrafluoroethylene is prepared by redox polymerization. Vinyl.
   Add various additives into the reaction kettle; the tetrafluoroethylene monomer goes into the polymerization pot in the gas stage, change the temperature level to 25 ℃, after that include a specific quantity of activator (salt metabisulfite), and start the polymerization via the redox system.During the polymerization process, the monomer was continuously added to maintain the polymerization pressure of 0.49-0.78MPa. The dispersion obtained after polymerization was diluted with water to a specific concentration, and the temperature was adjusted to 15-20ºC. After coagulation with mechanical stirring, it is washed with water and dried namely. This product is a fine granular resin.
