TCW
Description
The TCW profile is a shaft seal composed of a single metal cage with rubber grooves on the outside of the cage, a primary sealing lip with integrated spring and an additional anti-pollution lip.
* Very good static sealing
* Very good thermal expansion compensation
* Greater roughness is allowed in the housing
* Reduced risk of corrosion
* Easy to assemble with very
* limited bounce-back effect
* Sealing for low and high viscosity fluids
* Modern primary sealing lip with low radial forces
* Protection against undesirable air contaminants

MATERIALS
MATERIALS
ACM
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.
| Chemical resistance | Mineral oils (motor oils, gear box oils, ATF oils) Atmospheric and ozone agents |
|---|---|
| Compatibility issue | Glycol-based brake fluids (Dot 3 & 4) Aromatic and chlorinated hydrocarbons Water and steam Acids, alkalis and amines |
| Temperature range | -25°C to + 150°C (short-term peak at +160°C) -35°C / +150°C with particular ACMs |
EPDM
As an Ethylene Propylene Diene Monomer copolymer, EPDM is commonly used for hot water taps, cooling systems, brake systems, dishwashers and washing machines.
| Chemical resistance | Hot water and steam up to +150°C Glycol-based brake fluids (Dot 3 & 4) and silicone-based brake fluids (Dot 5) Organic and inorganic acids Cleaning agents, sodium and potassium alkalis Hydraulic fluids (HFD-R) Silicone oils and greases |
|---|---|
| Compatibility issue | Mineral oils and greases Hydrocarbons Low impermeability to gas |
| Temperature range | -45°C / +150°C (short-term peak at +175°C) |
FKM
Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems.
| Chemical resistance | Mineral oils and greases, ASTM n°1, IRM 902 and IRM 903 oils. Fire-resistant liquids (HFD) Silicone oils and greases Mineral and vegetable oils and greases Aliphatic hydrocarbons (propane, butane, petroleum) Aromatic hydrocarbons (benzene, toluene) Chlorinated hydrocarbons (trichlorethylene) Fuel (including high alcohol content) Atmospheric and ozone agents |
|---|---|
| Compatibility issue | Glycol-based brake fluids. Ammonia gas. Organic acids with a low molecular weight (formic and acetic acids) |
| Temperature range | -20°C / +200°C (short-term peak at +230°C) -40°C / +200°C with particular FKMs |
HNBR
This HNBR-based rubber is obtained through selective hydrogenation of the NBR’s butadiene groups. It is commonly used for power-assisted steering and for air conditioning.
| Chemical resistance | Aliphatic hydrocarbons Mineral and vegetable oils and greases Fire-resistant fluids (HFA, HFB and HFC) Diluted acids, saline solutions and bases for operation at an average temperature Water and steam up to +150°C Atmospheric and ozone agents |
|---|---|
| Compatibility issue | Chlorinated hydrocarbons Polar solvents (ketones, esters and ethers) Strong acids |
| Temperature range | -30°C / +150°C (short-term peak at +160°C) -40°C / +150°C with particular HNBRs |
NBR
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 resistance | Aliphatic hydrocarbons (propane, butane, petroleum, diesel fuel) Mineral oils and greases Fire-resistant fluids (HFA, HFB and HFC) Diluted acids, low-temperature alkaline and saline solutions Water (up to +100°C max) |
|---|---|
| Compatibility issue | Fuels with 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 particular NBRs |
