General:

It is a special version of NBR designed for applications where there is direct contact between rubber and petrol.

The general characteristics with the advantages and defects remain almost the same as anti-oil.

Technical features:

• Resistance to oils and fuels
• Mechanical strength 1OMPa (20 MPa mark)
• Good water resistance
• Good resistance to tearing and abrasion
• Good accessibility
• Good gas impermeability

Defects:

• Poor ozone resistance.
• Poor weather resistance.
• Poor direct sunlight resistance.
• Poor resistance to UV radiation.
• Poor dielectric properties.
• Flame resistance nothing.
• Non-resistant to glycol base.
• Poor resistance to polar ions (ketones, ethers, esters) to chlorinated hydrocarbons, to aromatic solvents.

Applications:

Mechanical: This special version is used when the rubber is in direct contact with the gasoline. A normal NBR would swell.
Food: on request the food version of the sister “anti-oil”
Electric: poor dielectric quality limits its use in this field.
Chemical: Not being born to resist chemical agents its application in this world is limited. It is advisable to always know the substances in contact and verify their compatibility with substance tables.
