|Natural Rubber, or NR, was the first commercially viable elastomer ever developed and is still the only non-synthetic rubber in widespread use. Natural rubber currently accounts for almost 40% of the world's elastomer consumption, as it is frequently blended with other rubbers to derive an ideal combination of properties. Derived from a liquid of the Hevea tree, NR latex is a low cost material that may contain relatively high levels of organic and inorganic impurities. It is ideal for applications that require good resistance to abrasion, gouging and cut growth. Also, because it experiences little heat buildup during flexing, it is also commonly specified when shock and dynamic load requirements are deemed critical. Natural rubber is tough, long lasting and can be compounded for service at temperatures as low as -65°F. It is also easily bonded to metal and fabrics.|
