Product Description:
Encapsulated O rings, also known as "fluorinated O rings" and "Silicon-coated O rings"
also have "Double-layered O rings".The external use of FEP or PFA special high temperature resistant fluoroplastic,
and internal coated elastic rubber (fluorine rubber/silicone, etc.) Besides, O rings coated with FEP
or PFA have good resistance to swelling and chemical stability (unless they are attacked by alkali metals,
fluorine, and some halogens at high temperatures) and have good elasticity near the rubber O rings.
FEP or PFA has a very low coefficient of friction (only 0.08 to 0.2). Besides,
it has excellent gas permeation resistance.
Product Description:
Fep Core Ring Silicon Rubber Coated Ptfe Material Fep Encapsulated Silicone O rings.
Encapsulated O Rings have an elastomer core which is encapsulated in a jacket of PTFE fluoropolymer.
Typically these are manufactured with FKM or Silicone or EPDM and the cores are FEP or PFA jackets.
Encapsulated O Rings are widely used in the food & beverages industry, pharmaceutical,
and chemical processing, where hygiene and chemical resistance is needed.
As standard O Rings have poor chemical resistance and solid PTFE O Rings don't have the elasticity
for long-term sealing, the choice is the encapsulated O Ring.
PTFE coated encapsulated O-rings are designed to combine the sealing properties of the rubber O-ring
with the chemical resistance of PTFE. They are generally manufactured from FKM or silicone rubber
and are coated in a thin molded layer of PTFE FEP or PFA.
This provides a unique seal popular for high friction and aggressive chemical applications.
FEP encapsulated O-rings are our most common and are resistant to solvents and chemicals
(except for alkaline metals, fluorine and some halogenated compounds at high temperatures).
They have a low coefficient of friction and a very low permeability to gases making them suitable
for harsh environments. PTFE coated encapsulated o-rings also have a good elastomeric memory.
We can also supply rigid PTFE o-rings which have a high compression set.
FEP-encapsulated O-Rings (Fluorinated Ethylene Propylene):
* Outstanding chemical and corrosion resistance
* Low coefficient of friction
* Resilience with choice of elastomeric cores
* Low compression set
* No mould charge
* Solid silicone, Viton cores
PFA-encapsulated O-Rings (Perfluoroalkoxy). Same as FEP above but with these added benefits:
* Higher mechanical strength
* Better flex-life
* Low vapor permeation
* Excellent stress and crack resistance
* Longer wearability
* Solid silicone & Viton core
Function of the rubber o ring:
O-Rings are used in sanitary pipeline systems for the Auto, Machinery, Food, Dairy, Beverage,
Pharmaceutical and Bio-Tech industries. Rubber Fab offers a full line of AS568 dash numbers, metric,
and specialty o-ring sizes that are manufactured using EPDM,NBR,FKM Fluoroelastomer,Buna-N,PTFE,Silicone and so on.
The o-rings used in cylinder, pump, railcars, truck, washing machine, instrument and meter,
mine equipment, pipeline, household appliances, automobile, steamboat, industrial electrical equipment,
building door& window, construction machinery, construction bridges and tunnel.
1.Mechanical sealing,pressure vessel,gas compressor,reaction vessel,heat exchanger,boiler,filter and so on.
2.It can be used for all kinds of electronic products in a wide range,such as camera,mobile phone,printer,computer.
3.Used for automobile windows and doors,etc...
4.Silk screen printing,spray coating,laser etching,back-lighted,hard/epoxy coating keypads.
