Naturkautschuk (natürliches cis-Polyisopren NR)
| The rubber: |
A natural cis-polyisoprene. |
| Resistance and properties: |
This is “the real thing”. The outstanding strength of natural rubber has ensured its position as the preferred material in many engineering applications. It has a long fatigue life and high strength (even without reinforcing fillers unlike SBR). The resistance to high temperatures is limited. The rubber is suitable for continuous use up to 70 degrees Celsius, intermittent exposure up to +100 degrees Celsius. It can maintain flexibility down to – 60 degrees Celsius if compounded for this purpose. |
| Downsides: |
It’s main disadvantage is the poor aging and weather resistance, as its lack of resistance to oxygen, ozone and oil. |
| Applications: |
Acrylic rubber is used in the tyre industry and shock isolators. |
