The advantages of this material are:

High temperature resistance - working temperature up to 260 ℃.

Low temperature resistance - good mechanical toughness;

5% elongation can be maintained even when the temperature drops to - 180 ℃.

Corrosion resistance - for most chemicals
and solvents, it is inert and resistant to strong acids and alkalis, water and various organic solvents.

Weather resistance - has the best aging life in plastics.

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

Non adhesion - the minimum surface tension
in a solid material that does not adhere to any substance.

No toxicity - it has physiological inertia.
It can be implanted as artificial blood vessel and organ for a long time
without adverse reactions.

Polytetrafluoroethylene (PTFE) is the most
widely used fluoroplastics, accounting for about 60% of its total demand. It
has excellent performance and is trusted by users. The application of other
fluoroplastics in semiconductor, medical, wire coating and other fields is also
expanding. The use of fluoroplastics can be summarized as follows:

1. The application of Pu plastics in drug
resistance is not limited to the manufacture of sealing rings, gaskets and pipe
fittings, but also used in other corrosion-resistant parts (such as pipes).
With the progress of raw materials and processing technology, the selection
range of fluoroplastics molding methods has been expanded: for example, injection
molding can greatly improve the production efficiency, cutting process can be
used in small batch production, the development of PTFE bonding and welding
technology makes it possible to manufacture large storage tank and equipment
lining, FEP powder spraying process makes processing more flexible and
convenient. Fluoroplastics have been widely used in semiconductor production to
prevent corrosion and pollution.

2. The friction coefficient of
polytetrafluoroethylene in mechanical industry is small, and its static
friction coefficient is lower than that of dynamic friction coefficient. It can
be used in low speed and high load field, such as in civil engineering,
chemical engineering, bridge and other structural parts, which can solve the
expansion and contraction problems caused by thermal expansion and vibration.
Specific applications include:

(1) Anti pollution machinery (such as
textile, paper, pharmaceutical, food machinery) bearing sleeve;

(2) Machinery for conveying alkali, solvent
and other non lubricating liquids (such as blenders, dyeing machines, pumps);

(3) Shaft sleeve working in acid, alkali
and other corrosive environment (such as electroplating bath chemical
equipment);

(4) No oil lubrication (such as oxygen
making equipment);

(5) Unit oil lubrication (such as ultra-low
temperature refrigerator, liquid fuel pump);

(6) Sliding parts working in the
environment with poor oil lubrication effect (adding high temperature dryer,
furnace platform afternoon, furnace conveyor belt);

(7) Sliding parts under low speed and high
load condition (movable support).

3. Fluoroplastics are flame-retardant
materials in electrical field. They have high critical oxygen index and
corrosion, and can be used as insulation layer of wires.

Etfelpvdf has high insulation resistance,
high insulation strength and good mechanical strength. It is commonly used in
cables of computers and communication machines. It can be used in oil well and
small nuclear reactor cable by its weather resistance and radiation resistance.
Because of its low relative permittivity and dielectric loss at high frequency,
it can be used in communication equipment and high frequency electric
instrument. PTFE can be used as antistatic material and heating element
material by mixing PTFE with carbon black and carbon fiber. PVDF can also be
made into piezoelectric components for radio industry and instrument industry.

4. non sticky use of fluorine plastic non
sticky can make kitchen equipment (such as non stick pan, dim sum mold),
exterior wall coating of high building, foam molding mold, duplicator roller
and so on. In addition, it has been widely used in artificial blood vessel,
heart valve and other medical soil engineering materials, gas separation
membrane, waterproof and breathable composite fabric.
