Natural Rubber (NR)

Natural Rubber (NR)

Natural Rubber (NR) is the most widely used rubber in the world, all synthetic rubbers have been developed from this rubber.

Natural rubber is qualified as oil non-oil resistant, and its working temperature is 70º C. Both these features are not the most favourable, but natural rubber offers other properties that make it irreplaceable, such as:

  • Excellent mechanical characteristics, even in compounds without load, highlighting the tensile and tear strength.
  • Excellent resilience
  • Good compression set
  • Good resistance to low temperatures

On the other hand of these characteristics we must point out:

  • Lack of resistance to weathering and ozone, so it’s necessary to protect it with anti-ozone and anti-rust products.

As for its use, the manufacture of large, competition tyres point out as per their hard performance conditions.
