Chinese name: ptfe

 

English name: polytetrafluoroethylene, PTFE

 

Definition: a repeat unit for polymer. Usually by tetrafluoroethylene addition polymerization. Good heat resistance, excellent solvent resistance.

 

 

Ptfe (Polytetrafluoroethene, generally referred to as the "non-stick coating" or "material" easy clean huo; is a kind of using all the hydrogen atoms in the fluorinated polyethylene synthetic polymer materials. This material has good acid resistance to alkaline, the characteristics of different organic solvent resistance, almost insoluble in all solvents. At the same time, ptfe has the characteristics of high temperature resistance, low coefficient of friction of it, so can make lubrication, and also become the easy clean huo ideal coating of pipe lining.

 

Chinese alias: PTFE; Teflon; Teflon; Teflon; Teflon; F4; The king of the plastic; テ フ ロ ン (Japanese) 【 abbreviations for PTFE, brand name Teflon®, around different Chinese translation: mainland translation for teflon & reg;, translated into teflon & reg; Hong Kong, and Taiwan translated as teflon & reg;]

 

Chinese commodity name "teflon", "teflon" (teflon), "teflon", "fu lung", "teflon", etc. It is composed of tetrafluoroethylene by polymerization of polymer compound, its structure is short form for - - CF2 - CF2 - n -, excellent chemical stability, corrosion resistance, corrosion resistance in the world today is one of the best materials, in addition to melt alkaline metal, metal three liquid chloride, chloride and fluoride fluoride fluoride, ingeneral, all other chemicals in aqua regia boil also doesn't change, is widely applied to various occasions need resistance to acid, alkaline and organic solvents. Sealing, high lubrication is not sticky, electric insulation and good anti-aging ability, excellent heat resistance (at + 250 ℃ to 180 ℃ temperature long-term work). Ptfe itself no toxic to people.

Using temperature - 190 ~ 250 ℃, allow quenching heat, or alternating operation.

 

At present, the king of all kinds of plastic products has been in the chemical industry, machinery, electronics, electrical, military industry, aerospace, environmental protection and Bridges and other fields of national economy has played a pivotal role.

Polytetrafluoroethylene (PTFE) conditions of use chemical industry, petrochemical, oil refining, chlor-alkali, acid, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dye, coking, coal gas, organic synthesis, non-ferrous smelting, steel, atomic energy and polymer filtration material, high purity product (e.g., ionic membrane electrolysis), viscous material transfer and operation, highly strict health food, beverages and other production departments.

 

 

 

Use the advantages:

 

High temperature resistant, use the working temperature of 250 ℃.

Good low temperature resistance, good mechanical toughness; Even if the temperature drops to 196 ℃, also can keep 5% of elongation.

Corrosion - to most chemicals and solvents, inert, ability strong acid strong alkaline, water, and a variety of organic solvents.

Aging resistance to climate, with a plastic in the best of life.

High lubrication - is the lowest coefficient of friction in solid materials.

Not adhere to, is the smallest, the surface tension of the solid material does not adhere to any material.

Non-toxic, having physical inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.

Ptfe relative molecular mass is bigger, for hundreds of thousands of low, high of more than ten million

, in general, for millions of polyethylene (degree of polymerization of the order 104, and only in 103). General crystallinity is 90 ~ 95%, melting temperature is 327 ~ 342 ℃. Ptfe CF2 unit according to the sawtooth shape are arranged in molecules, due to the hydrogen fluorine atom radius is larger, so the adjacent CF2 unit can't completely according to the trans cross orientation, it forms a spiral twisted chains, fluorine atoms almost covers the entire surface of the polymer chain. This molecular structure to explain the properties of the ptfe. 19 ℃, the temperature is lower than form 13/6 screw; Phase transition in 19 ℃, molecules are slightly loose, spiral form 15/7.

 

 

Chemical properties:

 

Atmospheric aging resistance, irradiation resistance and low permeability: long-term exposure to the atmosphere, surface and function remain the same.

Incombustible, limit oxygen index below 90.

Acid-proof alkaline, not soluble in strong acid, alkaline and organic solvents (including acid, the fluorine antimony sulfonic acid).

Oxidation resistance, corrosion ability of strong oxidizer.

Acid and alkaline resistance: a neutral.
