Natural Rubber | NR | Organic Rubber

Natural rubber (NR) is organically found in our environment and made from latex, which is found in certain plants

and trees.   There are about 200 different plants in the world that produce latex, however approximately 99% of natural rubber is actually derived from a single type of tree called Hevea Brasiliensis.  Most people simply refer to this species of tree as the rubber tree.

Natural rubber is a polymer of isoprene, containing chains of molecules that, when stretched apart, will spring right back together again upon release.  This is why rubber is considered to be elastic.

This material has excellent resilience, along with good tensile strength, elongation and resistance to abrasion.  Natural rubber also has favorable compression set, and is often chosen for its ability to adhere to metal and other materials.

The synthetic form of natural rubber is polyisoprene, which is often used as a substitute to organic natural rubber.

Natural rubber can be molded, extruded, run in rubber sheet form, cut into gaskets or strips, and can be color matched with ease.  Our technical team can create a custom compound to meet specific requirements that standard rubber compounds can't meet. 

Natural rubber is a good choice for applications requiring resilience, abrasion and tear resistance. It also has high tensile strength, and good compression set.
