Description
Natural rubber is the vulcanized product of the juice of the Hevea tree (latex). Until the invention of synthetic elastomers in the 1930’s, NR was the only polymer available for O-ring manufacture. NR has high tensile strength, high resilience, high abrasion and high tear resistance, good friction surface, and excellent adhesion to metals. Mainly used for dampeners due to its ability to absorb vibration. Also used in food and beverage, and non-hydraulic sealing applications.


Application Advantages

  • Excellent compression set

  • Good resilience and abrasion

  • Good surface friction properties


Limitations

  • Poor resistance to attack by petroleum oils

  • Poor ozone, UV resistance
