RUBBER PARTS

}

FKM (fluorinated rubber)

Rubbers must offer a strong compression set to guarantee that the axial force is maintained while the seal is in use.

Depending on their structure and fluorine content, fluoroelastomers can vary in terms of chemical resistance and

resistance to cold.

Resistance to chemicals

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 / +180°C (short-term peak at +200°C)

HNBR (Hydrogenated Nitrile Butadiene Rubber)

This HNBR-based elastomer is obtained through selective hydrogenation of the NBR's butadiene groups.

Resistance to chemicals

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
