About Viton
O rings
This type of O rings widely used
and is the simplest form of seal that is unsurprising given that they are
inexpensive, easy for mounting, and reliable. it is found in pumps, gearboxes,
NASA space shuttles and engines. It is especially used in shaft seals, enabling
rotary and linear movement in dynamic applications.
It has excellent resistance to
high temperatures such as mineral oil, oxygen, ozone, fuels, aromatics, organic
solvents and other chemicals. Low temperature is not favorable for the static
application that is limited to -15° F. If you go with dynamic the lowest
service temperature is between 5° F and 0°F.
Performance
It has the high performance
factor in advanced fuel and engine systems and provides improved system
reliability for extreme temperatures especially for transmission fluids, fuels,
oils and acid condensates. It helps to extend the maintenance intervals and
protects seal failure. For static applications, sometimes low temperature
resistance is not preferred for traditional Viton O rings.
Difference between black and brown color?
These two colors are functionally
interchangeable. It depends on the formulation the one may slightly softer than
other and black has carbon black. The Viton is a DuPont trademark for a
specific fluroelastomer polymer that is made up of vinylidene fluoride-hexafluoropropylene
copolymer known as Viton A resin. The magnesium oxide added as a proton
acceptor to react with the small amount of HF those results from polymerization
of the resin. Different manufacturers use different formulas, so it varies in
color and its physical properties.

The Viton o ring has polymer,
curatives, metal oxides, calcium oxides, etc, and processing aids as necessary.
Usage of different compounding materials for formulating compounds based on
Viton R thus has a significant effect on the performance of vulcanizate in the
services.
WVPE is a largest online
manufacturer of O-rings of Viton types
in the UK over twenty years. We have an excellent range of O rings materials
such as Viton (FKM, ETP), Ethylene Propylene (EPDM) and Aflas (TFE).
