1. What material is Ptfe
The Chinese name of PTFE is polytetrafluoroethylene. ptfe emulsion is a kind of polyfluorotetraethylene polymer chemical material. It is widely used in packaging, electronic and electrical, chemical energy, corrosion-resistant materials, Teflon high-performance special coatings are based on poly The fluorine coating with tetrafluoroethylene as the base resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon, etc. (all are Teflon transliterations) .
PTFE coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction. It has comprehensive advantages that other coatings can’t compete. Its flexibility in application allows it to be used in almost On products of all shapes and sizes.
PTFE can be formed by compression or extrusion processing; it can also be made into water dispersion for coating, impregnation or making fibers. Polytetrafluoroethylene is widely used in industries such as nuclear energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, metal surface treatment, pharmaceuticals, medical treatment, textiles, food, metallurgy and smelting, etc. , Corrosion-resistant materials, insulating materials, anti-stick coatings, etc., making it an irreplaceable product.

The mechanical properties of Ptfe are relatively soft. Has very low surface properties.
High temperature resistance: long-term use temperature 200~260 degrees;
Low temperature resistance: still soft at -100 degrees;
Corrosion resistance: resistant to aqua regia and all organic solvents;
Weather resistance: the best aging life among plastics;
High lubrication: has the smallest coefficient of friction in plastics (0.04);
Non-sticky: It has the smallest surface tension among solid materials and does not adhere to any substances;
Non-toxic: with physiological inertness; excellent electrical properties, is an ideal C-level insulating material.
Second, black ptfe tube
The black ptfe tube is made of suspended polytetrafluoroethylene resin and mixed with filler after grinding. The types of fillers include metal fillers (such as copper powder, molybdenum powder, nickel powder, etc.); inorganic fillers (such as graphite, molybdenum disulfide, glass powder, ceramic powder, etc.); organic fillers (such as polyimide, polyimide, etc.) Alum, etc.).
The black PTFE tube can be mixed and used with one or several fillers as required. In addition to the basic retention of PTFE, it also overcomes the shortcomings of large cold flow deformation and poor wear resistance during PTFE processing; usually, the size of the product under heat or load is implicitly improved, the thermal conductivity is improved, and the flexibility is , The shape is stable, the linear expansion coefficient is reduced, the creep resistance is improved, and the compressive strength and hardness are increased. It is a good wear-resistant material
Black PTFE tube (Polytetrafluoroethene, generally referred to as "non-stick coating" or "easy to clean material"; is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has acid resistance Alkali, resistance to various organic solvents, almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is very low, so it can be used for lubrication, and it has become an easy-to-clean wok The ideal coating for the inner layer of water pipes. Polytetrafluoroethylene is used in atomic energy, defense, aerospace, electronics, electrical, chemical, machinery, instrument, meter, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and smelting, etc. It is widely used in the industry as high and low temperature resistant, corrosion resistant materials, insulating materials, anti-stick coatings, etc., making it an irreplaceable product.
