Full
name also called PTFE gaskets or PTFE gasket abroad , gasket by
PTFE rods, tubes, plate by the mechanical cutting or cutting into
the flat gasket, V gaskets, piston rings, such as ball valve gasket
has corrosion resistance, Anti-aging and non-conductive and
other good characteristics. Ptfe pH value 0 to *4 (molten alkali
metals and fluorine, except under high temperature and high
pressure. The in - between **0℃~
**0℃can have good mechanical strength.
*0 mpa pressure When
the temperature is below **5℃. PTFE gaskets gasket will become
fragile. Pure PTFE gaskets gasket sealing products is a kind of
clean, not any contact with the material to its formation
pollution, can be widely used in food, medicine and other
industries. Ptfe is composed of tetrafluoroethylene by
polymerization of polymer compounds, it has excellent chemical
stability, corrosion resistance, corrosion resistance in the world
today is one of the best materials, in addition to the molten metal
liquid and sodium fluoride, ingeneral, all other chemicals in aqua
regia boil also doesn\'t change, is widely applied to various needs
the operation condition of the resistance to acid and alkali and
organic solvent), sealing, high lubrication is not sticky, electric
insulation and good aging resistance, large span of heat-resistant
(at + **0℃to
**0℃temperature long-term
work). High
temperature resistant, use the working temperature of
**0℃. Good low temperature resistance,
good mechanical toughness; Even if the temperature drops to
**6℃, also can keep 5% elongation.
Corrosion - to most chemicals and solvents, inert, acid alkali,
water and a variety of organic solvents. Weather - to be the best
in the plastic in aging life. High lubrication - is the lowest in
the friction coefficient in solid materials. Don\'t stick - is the
smallest, the surface tension of the solid material don\'t adhere
to any material. Non-toxic, has a physiological inertia, long as
artificial blood vessels and organs implanted without adverse
reaction.
