Chemical Designation: Natural Polyisoprene (NR) 

Molded natural rubber is best used in applications that require high pliability, tensile strength and tear resistance. A good choice for applications where product exposure includes acids, organic salts and alkalis. In addition, Natural Rubber is soft and has good flexing characteristics at low temperatures. It is wear resistant and non-toxic.   

Do not use Natural Rubber for outdoor applications where resistance to sunlight, oxygen or heat aging is an issue. Do not use this product for applications that involve petroleum derivatives or exposure to chemicals.
