Virgin PTFE Gaskets - Kaxite 2100
For
longer than 20 years, our gaskets production organization has produced
unique PTFE gaskets that meet up with consumer specifications for
effectiveness, dependability, and cost. All of our virgin PTFE gasket
are cut from 100% PTFE Teflon gaskets sheet with all range of dimension
sizes, thickness from 0.5 mm to 100mm all is available. Virgin PTFE
gaskets are chemically inert as well as water-resistant, but tend to
deform under use. For improved resistance to creep and cold flow, we
recommend Gore GR gaskets instead. Gore GR sheet gasketing is an
expanded PTFE for industrial applications.
We
can produce plus supply PTFE Teflon gaskets from 100% virgin PTFE in
excellent cost, or suggest compounds that contain PTFE and various
fillers for increased resistance to strong acids or caustics. In
addition, we can source expanded PTFE Teflon gasket material that is
much easier to compress and conforms to tough surface areas.
Temperature Range Of Virgin PTFE Gaskets
The
functioning temperatures of Virgin PTFE gaskets ranges from -200⁰C to
+260⁰C. It is the most commonly known non-stick material by using a
coefficient friction comparable to wet ice on wet ice. Most of the
people commonly utilise PTFE through a commonly seen trademark: Teflon,
which is a PTFE coating for non-stick household items.
Why Should You Use PTFE As A Gasket Seal?
Virgin
PTFE Gaskets are chemical resistant. Pure virgin PTFE gaskets can be
used in the most corrosive of environments and will not contaminate the
most sensitive medium. PTFE is utterly insoluble and possesses high
intrinsic purity and can be made with no pollution for ultra-pure or
corrosive purposes.
Virgin
PTFE Gaskets are completely resistant to attack by all chemicals
excluding molten alkali alloys and also a few fluorine elements at
raised temps and pressures. It is unaffected by lubricants, hydraulic
fluids, plane or rocket gasoline as well as atmospheric problems.
Which are the Disadvantages of Virgin PTFE Gaskets?
While
virgin PTFE gaskets are a fantastic selection for numerous programs, it
can have a very several disadvantages to be considered: It includes
almost no plastic ability to remember and is subject to creep, which can
be worthwhile when utilized for a seal, nonetheless to limit this
effect a version of PTFE with fillers should be used. virgin PTFE
gaskets is referred to as gentle and can harm or distort when being
clamped. It is going to not be described as being hard or having a high
tensile strength.
Applications of Virgin PTFE Gaskets
Virgin
PTFE Gaskets are commonly used in pipework and flanges where chemicals
are present, PTFE gaskets have an extremely low coefficient of friction
and good resistance to moisture and corrosion. The anti-stick properties
of the material mean PTFE is commonly found in applications with parts
that have linear or rotary movements.
Can PTFE Gasket be Used in Food Applications?
Because we all are aware of PTFE is Teflon® lining for cooking equipment which is popular globally. It comfirms to FDA standard.
PTFE VS Teflon®
PTFE is sometimes referred to as Teflon® (DuPont), Teflon® is the Trademark of PTFE.
PTFE and PTFE Fillers.
The
fillers of ptfe increase creep resistance, hardness, chemical
resistance, and compliance requirements for specific industries. PTFE
can have fillers added blending with base PTFE resin to enhance specific
properties.
Glass
fibre is often added in different percentages and different fibre
lengths, generally glass fibre increases wear resistance with less
deformation under load, creating a harder material with lower thermal
expansion.
Carbon
Fibre filled PTFE – normally at a ratio of 5% to 25 carbon fiber filled
in PTFE, it has better resistance to pressure under load as it is a
harder material, used in strong alkali and hydrochloric acid which is
where glass fibre can fail.
Graphite
filled PTFE – Excellent in high speed contact applications where it
offers little wear, including when wearing against soft metals.
Bronze filled PTFE – excellent creep resistance and high thermal conductivity.
Glass Moly-filled PTFE – makes a very stiff, rigid material, chemically unreactive and further reduces friction.
Polymide PTFE – good friction against soft metals.
Stainless Steel Filled PTFE – stiff, hard PTFE material.
