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 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 features, 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 features 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 stand out due their intense performance conditions.
