What is 1. Ptfe?
The Chinese name of PTFE is polytetrafluoroethylene. ptfe emulsion is a polymer chemical material containing polyfluorotetraethylene. It is widely used in packaging, electronic and electrical, chemical energy, corrosion-resistant materials. Teflon high-performance special coating is a fluorine coating with polytetrafluoroethylene as matrix resin. The English name is Teflon. Because of pronunciation, it is usually called Teflon, Teflon, Teflon, etc. (all translated by Teflon).
PTFE coating is a unique high-performance coating, combining heat resistance, chemical inertness and excellent insulation stability and low friction, with other coatings can not compete with the comprehensive advantages, its application flexibility makes it can be used in almost all shapes and sizes of products.
PTFE can be molded by compression or extrusion; it can also be made into an aqueous dispersion for coating, impregnation or fiber. PTFE in atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and other industries are widely used as high and low temperature resistant, corrosion resistant materials, insulation materials, anti-stick coating, 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: able to aqua regia and all organic solvents;
Weather resistance: the best aging life in plastics;
High lubrication: with the smallest coefficient of friction in plastics (0.04);
Non-stickiness: has the smallest surface tension in solid materials without adhering to any substance;
Non-toxic: physiologically inert; excellent electrical performance, is the ideal C- class insulation material.
2. black ptfe tube
The black ptfe tube is made of suspended polytetrafluoroethylene resin mixed with filler after grinding. 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, polyphenyl alum, etc.).
The black PTFE tube can be mixed with one or several fillers as required. In addition to basically ensuring the 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 improved, the thermal conductivity is improved, the flexibility is changed, the shape is stable, the linear expansion coefficient is reduced, the creep resistance is improved, and the compression strength and hardness are increased. It is a good wear-resistant material.
Black PTFE tube (Polytetrafluoroethene, commonly referred to as "non-stick coating" or "easy-to-clean protective material"; It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is very low, so it can be used for lubrication, and it has also become an ideal coating for the inner layer of easy-to-clean wok and water pipe. Polytetrafluoroethylene is widely used in atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and other industries as high and low temperature resistant, corrosion-resistant materials, insulation materials, anti-sticking coatings, etc., making it an irreplaceable product.
