The Custom Polyisporene Natural Rubber Molding Experts
Chemical Designation: Natural Polyisoprene (NR)
Molded polyisoprene 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 Polyisoprene 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.
- Good sealing properties
- Resistant to electrolyte solvents
- Low compression set
What is Natural Rubber?
Natural rubber, also known as polyisoprene natural rubber, consists of polymers of the compound isoprene as well as impurities from other organic compounds and some water. It is harvested in the form of latex from the sap of rubber trees. This latex is then refined into natural rubber for processing. Natural rubber is both an elastomer and a thermoplastic. Vulcanizing natural rubber creates a thermoset material.
Polyisoprene natural rubber is used widely in various applications and industries whether alone or as a compound with other materials. Some of its advantages include high durability, stretch ratio and water impermeability.
