Introduction of 1. polychlorotrifluoroethylene (PCTFE):

 

Chinese alias: PCTFE

 

英文名称：poly(chlorotrifluoroethylene)

 

英文别名：halocarbon oil 27 insect cell*culture tested;Fluorolube grease;PCTFE

 

Molecular formula: C2ClF3

 

Molecular weight: 116.4693 InChI: InChI = 1/C2ClF3/c3-1(4)2(5)6

 

Density: 1.9

 

Melting point: 210 ℃

 

PCTFE material, (poly trifluoroethylene) domestic commonly known as: trifluoro, solid density 2.1~2.2, melting point 208~210 ℃. Resistance to heat, acid, alkali and organic solvents (except halides), but not

 

Molten caustic and elemental fluorine. Strong chemical resistance, can be used as engineering plastics. Tensile strength 3.096~4.135 MPa (316~422 kgf/cm2). General application to performance requirements

 

High chemical equipment, insulated cables, radios, capacitors and heat or low temperature resistant accessories. It has excellent rigidity, low temperature resistance and cold flow resistance, and is the principle of low temperature and high pressure conditions.

 

Sealing materials, in the field of high-tech has a special purpose.

2. Polychlorotrifluoroethylene (PCTFE) Common Products

 

Although PCTFE can be processed by melting, it is difficult to process due to its high melt viscosity and degradation tendency, which leads to the deterioration of the performance of processed products. PCTFE rod resins can be made into pellets for molding and extrusion. Membrane

 

The thickness is 0.001-0.010 inches, and it can also be made into rods and tubes. Polychlorotrifluoroethylene (PCTFE) profiles PCTFE polychlorotrifluoroethylene plates and rods are made of polychlorotrifluoroethylene resin by molding, which can be used.

 

Widely used as corrosion-resistant structural materials, automation equipment accessories, ideal valve parts for cryogenic liquids, equipment anti-corrosion lining, transparent sight glasses, vacuum sealing materials, electronic and electrical components, medical appliances

 

Components, motor and instrument parts, etc.

The PCTFE resins distributed in the U.S. market include 3M's Kel-F brand, Daikin's Daiflon brand, and AlliedlSignal's Acfon brand.

 

5. Polychlorotrifluoroethylene (PCTFE) material application industry(For example, some industries)

 

● PCTFE products in the electrical and communication industry are used for high-frequency coaxial connectors, adapters, attenuators, etc. PCTFE film is used to manufacture capacitors, radio insulation gaskets, insulated cables, motors and transformers.

 

The ideal insulation material.

 

● Various gaskets and sealing seats for household appliances such as air conditioners and refrigerators in the electronic and electrical industry. Wire and cable, instrument insulation sleeve, capacitor, LCD heat shock resistant film, radio insulation, motor,

 

Transformer insulation, etc.

 

● Fluoroplastics in machinery manufacturing industry have the characteristics of corrosion resistance, aging resistance, low friction coefficient, non-stickiness, wide temperature range and good elasticity, which make them very suitable for manufacturing high corrosion resistance requirements and use temperature.

 

All kinds of mechanical equipment parts, sealing products, etc. with a degree higher than 100 ℃.

 

●Fluoroplastics in chemical and pharmaceutical industry have become the main corrosion-resistant materials in petroleum, chemical, pharmaceutical, textile and other industries due to their excellent corrosion resistance.

 

● Decorative construction industry exterior wall decoration and application, bridges, ships with support slider.

 

● Other application industries Other types of insulation parts, seals, self-lubricating parts, light transmission parts, anti-corrosion containers, etc.

5.6PCTFE rod transport hydrofluoric acid will react?

 

It won't. There are many substances that do not react with hydrofluoric acid.

 

Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, a clear, colorless, corrosive liquid with a strong pungent odor. Has a strong corrosive, can strongly corrode the vast majority of metal, glass

 

and objects containing silicon.

 

Theoretically, because the ability of hydrogen atoms and fluorine atoms is relatively strong, and there are hydrogen bonds between hydrogen fluoride molecules in aqueous solution, hydrofluoric acid can not be completely ionized in water, so the low concentration of hydrogen fluoride

 

Acid is a weak acid, but when concentrated (5mol/L or more), self-ionization will occur. At this time, hydrofluoric acid is a very acidic acid.

 

However, hydrofluoric acid does not react with every substance. If so, what container can be used to hold it?

 

Hydrofluoric acid reacts with silicon and silicon compounds to generate gaseous silicon tetrafluoride, which can corrode glass, so it cannot be used in glass products. But it will not corrode plastics, paraffin, lead, gold, platinum and other substances, so all

 

Plastic containers are used to hold hydrofluoric acid.

 

5.7PCTFE rod praise

 

Dankai PCTFE rods are well received at present. Apart from the relatively expensive price of the products themselves and the scarcity of the market, the raw materials are scarce and sometimes they are out of stock (for supply).

 

5.8PCTFE rod surface not only

 

PCTFE rod surface not only generally has many reasons, but nothing more than: a, PCTFE material problems; B, processing technology problems, c, packaging, transportation caused by wear, d, other. Details can be based on

 

Specific application environment (application scenario) to answer.

 

5.9 National standard for PCTFE bars

 

It is recommended to refer to the specific specifications of PTFE products (PCTFE products comply with relevant enterprise standards Q/MSF03-01-2002).

 

Which grades of 5.10PCTFE rods are good

 

The PCTFE resins distributed on the market are the Kel-F brand of 3M Company, the Daiflon brand of Daikin Company, and the Acfon brand of AlliedlSignal Company.
