Product Information
NR (Para) rubber sheeting
Natural rubber offers a good balance of properties, particularly for mechanical applications and can be compounded to produce high resilience, good tensile strength, low compression set and high tear properties over a wide range of hardnesses. The abrasion resistance of natural rubber is good. It has better
resilience, and maintains flexibility at lower temperatures better than most synthetics. However, natural rubber is less resistant to ozone, petroleum oils and fluids than some of the synthetics. The operational temperature range of natural rubbers is -40°C to + 85°C.

| Diluted acids and bases | Very good |
| Concentrated acids and bases | Good |
| Ozone | Medium |
| Oils and hydrocarbons | Not suitable |
