NR

NR (Natural Rubber) is a highly abrasion resistant, general purpose hose material,
ideal for use on slurries and pastes.

The greatest benefit of this material is its environmental properties. NR tends to be fully biodegradable and accounts for around 40% of the world’s elastomer consumption, and also has excellent water and air resistance properties. It also has good alcohol and dilute-acid and bases properties. Although NR can be used with water and dilute acids, alkalis and chemicals, EPDM is normally preferred for most aqueous applications.

Other benefits of NR:

• high tensile strength
• excellent bonding capabilities to metal substrate
• good vibration dampening characteristics

However, it has poor resistance to attack by petroleum oils, whilst also having poor ozone and UV resistance.
