Molten alkali metals, fluorine and several complex halogen
compounds are incompatible
with TEFLON resins and should be avoided.
Working Temperature Limits()
TEFLON encapsulation is the primary source of the chemical
compatibility of these O-rings. In general, TEFLON resins are
compatible with a broad range of chemical environments, including
those in the following chart.
Chemical Resistance
Core Elastomer(Viton or Silicone) + Teflon Jacket/Coating PTFE .
: -60 ~ +260 : 0.1 ~ 0.2 . (Compression set) . . FDA(21CFR
177.1550) Low extractable contaminants
FEP TeflonThe most versatile grade when considering verail
corrosion resistance, sealing capability,and temperature.
Operational temperature ranges from -450F to +400F (-267 to
+205)
PFA TeflonA fluorocarbon copolymer offering greaty improved
mechanical and creep properties at elevated operating temperatutes.
Operational temperature fanges from -450F to 500F (-267 to

Teflon (Pfa 450HP)The Teflon jacket is produced from Genuine Du
Pont Teflon Pfa 450HP which is the leading semicon high purity
fluoropolymer. Purity measured in pp/million allows universal use
throughout the wafer process industry.
International Seal-FNGP(USA) (High Purity PFA Teflon
Encapsulated O-Ring)
We produce a range of Teflon Encapsulated O-Rings which have
become popular in the Semiconductor Industry due to the cleanliness
of the encapsulated jacket
PFA
Core Materials (Viton, Silicone)The energising core of either
Viton or Silicone is used to energise the Pfa jacket and affect the
seal. As the encapsulation is seamless and resistant to permeation
conlamination is not possible. Should the jacket become damaged
then the seal must be removed and exchanged
Teflon PFA HP Polymer,Stress Cracking . 260 , .
Teflon PFA HP: A fully fluorinated polymer specafically tailored
to meet the semiconductorindustry's needs for high purity and
minimum extractables for most demanding uses, Components of Teflon
PFA HP have superior resistance to environmental stress cracking.
Rated for use at up to 500(260), Teflon PFA HP is unaffected by
virtually all chemicals and solvents.

Encapsulated O-rings are used in a variety of situations,
typically requiring chemically resistant seal materials. An added
advantage of these O-ring seals is the low contamination potential.
This is particularly effective in the semiconductor industry for
those applications demanding clean seals.

Chemical Resistance
Minimal swellChemically induced swelling can cause O-rings and
sealing components made of other rubbers to expand out of retaining
grooves, resulting in seal failures.Kalrez parts resist swelling
when exposed to a wide variety of chemicals and solvents. After six
months in a powerful trisolvent mixture of methyl ethyl ketone,
toluene and methylene chloride, Kalrez O-rings did not swell while
other rubber rings were severely affected.

Applications
Metal O-rings are successfully used in vacuum or high-pressure
systems as well in critical ranges for hydraulic units and
lubricating oils, jet engines and rocket propellants, liquid metals
and combustion gases. They yield positive and leakproof seals in
tube systems and with production processes for the chemical,
petrochemical, petroleum, natural gas and refinery industry. Many
manufacturers of reciprocating engines, heat exchangers, gas
turbines, pressure vessels, injection units, high-pressure filters
and other elements rely on metal O-ring as a permanent and highly
stressable seal. Some common applications are illustrated
