What Industries Are PCTFE Rods Used For?

I. Introduction to polychlorotrifluoroethylene (PCTFE):

English name: poly(chlorotrifluoroethylene)

Alias: 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°C

PCTFE material, (polytrifluoroethylene) domestic commonly known as: trifluoro, solid density 2.1 ~ 2.2, melting point 208 ~ 210 ℃. Resistant to heat, acid, alkali and organic solvents (except halides), but not resistant to molten caustic soda and elemental fluorine. Chemical resistance is very strong, can be used as engineering plastics. Tensile strength 3.096 to 4.135 MPa (316 to 422 kgf/cm2). Generally used in chemical equipment with high performance requirements, insulated cables, radio appliances, capacitors and heat or low temperature resistant fittings. With excellent rigidity, low-temperature resistance, cold flow resistance, it is an ideal sealing material for low-temperature and high-pressure working conditions, and has special uses in high-tech fields.

Second, polychlorotrifluoroethylene (PCTFE) common products

Although PCTFE can be melt processed, but due to the high viscosity of the melt, there is a tendency to degrade leading to the deterioration of the performance of the processed products, so the processing is difficult. PCTFE rod resin can be made into pellets for molding and extrusion. The film thickness is 0.001-0.010 inches and can be made into rods and tubes. Polychlorotrifluoroethylene (PCTFE) profiles PCTFE PCTFE sheets and rods are made from polychlorotrifluoroethylene resin by molding method, and can be widely used as corrosion-resistant structural materials, automation equipment parts, ideal valve parts for cryogenic liquids, anti-corrosion lining of equipment, transparent sight glass, vacuum sealing materials, electrical and electronic components, medical appliance components, electrical and instrumentation components, and so on.

Third, polychlorotrifluoroethylene (PCTFE) common specifications:

PCTFE sheet: (3-50mm)*500*500mm

PCTFE rod: (6-100mm) *1000mm long

PCTFE membrane material: 0.001-0.010 inches

Fourth, polychlorotrifluoroethylene (PCTFE) common resin raw materials

PCTFE resin marketed in the United States are 3M's Kel-F brand, Daikin's Daiflon brand, AlliedlSignal's Acfon brand.

V. Polychlorotrifluoroethylene (PCTFE) material application industry (examples of some industries)

● Electrical communications industry PCTFE products for high-frequency coaxial connectors, adapters, attenuators, etc. PCTFE film is the manufacture of capacitors, radio insulating pads, insulated cables, motors and transformers ideal insulating materials.

● Electrical and electronic industry air conditioners, refrigerators and other household appliances, a variety of gaskets, sealing seat. Wires and cables, instrumentation insulating sleeves, capacitors, LCD heat-resistant impact film, radio insulation, motor and transformer insulation, and so on.

● Machinery manufacturing industry fluoroplastics have the characteristics of corrosion resistance, aging resistance, low coefficient of friction and non-adhesion, wide range of temperature resistance, and good elasticity, which makes them very suitable for the manufacture of all kinds of machinery and equipment parts, sealing products, etc., which have high requirements for corrosion resistance, and the operating temperature is higher than 100 ℃.

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

● Decoration and construction industry exterior wall decoration and application, bridge, ship with support slider.

● Other applications of other types of insulating parts, seals, self-lubricating parts, translucent parts, corrosion-resistant containers, and so on.

Six, polychlorotrifluoroethylene (PCTFE) rods common problems

5.1 pctfe rod density

Solid density 2.1 ~ 2.2g/cc (g/cc);

5.2 How much is a kilogram of PCTFE bar material

According to different materials, processing different products, different sizes to confirm the price.

5.3 PCTFE rods

HONY plastic can be processed, PCTFE rods: (6-100mm)*1000mm long; some are in stock.

5.4 Will PCTFE rods react when transferring hydrofluoric acid?

No. There are many substances that do not react with hydrofluoric acid. There are many substances that do not react with hydrofluoric acid.

Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, clear, colorless, fuming corrosive liquid with a strong irritating odor. It is extremely corrosive, strongly corroding most metals, glass and objects containing silicon.

Theoretically, because of the relatively strong ability to combine hydrogen and fluorine atoms, and hydrogen bonding between hydrogen fluoride molecules in aqueous solution, so that hydrofluoric acid can not be completely ionized in water, so the low concentration of hydrofluoric acid is a weak acid, but concentrated (5 mol / L or more) will occur when the self-coupled ionization, this time, hydrofluoric acid is a very acidic acid.

However, hydrofluoric acid does not react with every substance, and if it did, what other containers could be used to hold it?

Hydrofluoric acid reacts with silicon and silicon compounds to produce gaseous silicon tetrafluoride, which can corrode glass, so it cannot be held in glass products. However, it will not corrode plastics, paraffin, lead, gold, platinum and other substances, so they are all plastic containers to hold hydrofluoric acid.

5.5 PCTFE rod surface is not light

PCTFE rod surface is not light generally have many reasons, but no more than: a, PCTFE material problems; b, processing technology problems, c, packaging, transportation caused by wear and tear, d, other. Details can be answered according to the specific application environment (application scenario).

5.6 National standards for PCTFE rods

It is recommended to refer to the specific specifications with reference to the specifications of PTFE products (PCTFE products in line with the relevant corporate standard Q/MSF03-01-2002).

5.7 PCTFE rods which grades are good

PCTFE resins distributed in the market include Kel-F brand of 3M, Daiflon brand of Daikin, and Acfon brand of AlliedlSignal.
