NBR/FKM/EPDM/PTFE/Viton Industrial Rubber Seal Ring
1: What is seal ring

A seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a plumbing system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.
Rubber seal is a common form of a device for preventing leakage of fluid from one part of a container to another, whether dynamic or static. It is also called as rubber ring, rubber sealing. The catagories of rubber seals includes hydraulic seals(piston ring, rod ring, wipers, guide ring, buffer ring...), rotary shaft seal(oil seal, coolant/water seal...), o rings and so on. Care is needed in design, since poor tolerances can cause extrusion of the seal under pressure. Material is also critical to performance, the following is the thermal Application of some materials:
Materials
Morgan seal Material Includes Nitrile rubber, fluorine rubber, ethylene propylene rubber, neoprene, chloroprene rubber, silicone rubber and so on.
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.
Chemical resistanceAliphatic hydrocarbons (propane, butane, petroleum, diesel fuel)
Mineral oils and greases
Fire-resistant fluids (HFA, HFB and HFC)
Diluted acids, alkaline and saline solutions for low temperatures
Water (up to +100°C max)
Compatibility issueFuels with a high aromatic content
Aromatic hydrocarbons (benzene)
Chlorinated hydrocarbons (trichlorethylene)
Polar solvents (ketone, acetone, acetic acid, ethylene-ester)
Strong acids
Glycol-based brake fluids
Atmospheric and ozone agents
Temperature range-30°C / +100°C (short-term peak at +120°C)
-40°C / +100°C with special NBRs
 
FKM (fluorinated rubber)
Depending on their structure and fluorine content, fluoroelastomers can vary in terms of chemical resistance and resistance to cold. This FKM-based rubber is very often used for high-temperature hydraulic and pneumatic systems, industrial valves, injection/fuel systems, motor seals and high-vacuum systems.

EPDM (Ethylene Propylene Diene Monomer rubber)
As an Ethylene Propylene Diene Monomer copolymer, EPDM is commonly used for hot water taps, cooling systems, brake systems, dishwashers and washing machines.
Chemical resistanceHot water and steam up to +150°C

This HNBR-based elastomer is obtained through selective hydrogenation of the NBR's butadiene groups. It is commonly used for power-assisted steering and for air conditioning.
Chemical resistanceAliphatic hydrocarbons
Mineral and vegetable oils and greases
Fire-resistant fluids (HFA, HFB and HFC)

VMQ (silicone rubber: methyl vinyl polysiloxane)
This FVMQ-based rubber is very often used for fuel systems.

FVMQ (fluorosilicone rubber)
The FVMQ has mechanical and physical properties that are very similar to those of VMQ. However, the FVMQ offers better resistance to fuels and mineral oils. However, resistance to hot air is not as good as that of VMQ.
Chemical resistanceAromatic mineral oils (IRM 903 oil)
Fuels
Aromatic hydrocarbons with a low molecular weight (benzene, toluene)
Temperature range-70°C / +175°C
 
ACM (Polyacrylate)
Polymers containing ethyl acrylate (or butyl acrylate) have a small amount of monomer, which is necessary for cross-linking; ACM is a material with better heat resistance than NBR. It is often used for automatic gearboxes.
