Natural Rubber (NR)

Natural rubber is produced from the latex of the Hevea brasiliensis, the chemical name of polymer is polyisoprene. Polyisoprene also can be synthesized by polymerization from its monomer isoprene. Natural rubber possesses many excellent physical properties including high resilience and strength, good abrasion resistance. The defects are like SBR, having poor resistant to hydrocarbon oil and not suitable in UV, oxygen, ozone because the double bond in the polymer backbone. But its poor weathering resistance can be modified by special additive.

For NR the service temperature can be designed from -50°C to 70°C, and up to 100°C at short time.
