Description

Chemical Resistance PTFE Coated Silicone Or FKM FKM Rubber O Ring With Different Standard

Description:Encapsulation ring is a special combination of two different materials of the inner

and outer layers of the sealing ring. PEP or FPA for outer layer, FKM, Silicone or EPDM for inner layer.

The covering ring has good chemical resistance (equal to FFKM ring),

and can withstand more than 99% of chemical media.

Wide temperature range (-30 degree to 260 degree) can maintain good sealing performance

(stability at 23 degrees Celsius). Due to the low friction coefficient of the outer material,

the covering ring has outstanding wear resistance, and can be used for static or dynamic sealing.

Ordinary rubber O-rings are easy to wear, have poor chemical resistance and gas permeability resistance.

Pure PTFE O-rings have high hardness and can resist compression but have poor elasticity.

The O-ring covered with FEP or PFA has good swelling resistance and chemical stability

(unless it is corroded by alkali metals, fluorine and some halides at high temperatures),

and it has good elasticity near the rubber O-ring. ,

The friction coefficient of FEP or PFA is very small (only 0.08~0.2),

and it has excellent gas permeability resistance.

These properties enable the coated O-ring to be truly used in harsh environments.

Application:

1. Pumps and valves
2. Reflect the container
3. Mechanical seal
4. Filter
5. Pressure vessel
6. Heat exchanger
7. Boiler
8. Pipeline flange
9. Gas compressor

Material data sheet:

The outer plastic
(FEP) Polyfluoroethylene propylene,
temperature resistance -20℃~200℃, general type
(PFA) Polyperfluorinated with alkoxy, temperature
resistance -20℃~260℃, high temperature resistance
type
Double-layer PTFE, high and low temperature
resistance, -50℃~260℃, special corrosion
Main material of inner rubber
Fluorine rubber (FKM)
Temperature resistance: -30～230℃
Hardness: 50-90 (Shore A)
Performance: corrosion resistance, oil resistance, pressure resistance, aging resistance, high temperature resistance and abrasion resistance, but poor cold resistance.
silicone rubber (VMQ)
Temperature resistance: -100～300℃
Hardness: 25-90 (Shore A)
Performance: Ozone resistance, UV resistance, corrosion resistance, high temperature resistance and weather resistance are excellent, but the mechanical strength, oil resistance, acid and alkali resistance are poor.
