Natural Rubber
NATURAL RUBBER
Description: Natural Rubber is the vulcanized product of the
juice of the Hevea tree (latex).
Temperature Range: Standard Compound: 60ºF to +220ºF.
(Dry Heat Only)
Hardness (Shore A): 40 to 90.
Features: Natural Rubber features low compression set, high
tensile strength, high resilience, high abrasion and high
tear resistance properties, with a good friction surface and
excellent adhesion to metals. Until the invention of synthetic
elastomers in the 1930's, Natural Rubber was the only polymer
available for Oring manufacture.
Still used today in FDA applications for food and beverage
seals, Natural Rubber features good resistance to organic
acids, alcohols and automotive brake fluid, with moderate
resistance to aldehydes and ketones.
Limitations: The poor resistance of Natural Rubber to attack
by petroleum oils was the primary reason for the research
and development of synthetic rubbers beginning in the 1930's.
Also readily deteriorated by exposure to sunlight and ozone,
Natural Rubbers have been predominantly replaced by "use
specific" synthetic rubbers in the seal industry of today.
