Blends of Natural Rubber - Novel Techniques for Blending
Blends of natural rubber with speciality synthetic rubbers, such as nitrile rubber and ethylene propylene rubbers, have, in the past, failed to combine the best properties of polymers, resulting in a poor return in terms of added value from the blending process.

Thermoplastic Elastomers Based on Natural Rubber
Thermoplastic elastomers (TPEs) based on natural rubber (NR)/polypropylene (PP) with different blend ratios were prepared and studied. The TPEs were obtained by dynamic vulcanization of NR/PP using a sulfur (S)/N-tert-butyl-2-benzothiazolesulphenamide (TBBS) and tetramethylthiuram disulphide (TMTD) curative system during processing in the melt state in an internal mixer equipped with cam rotors.

General Properties of Elastomers - ELBEX Corporation
Crude natural rubber is found in the juices of many plants (shrubs, vines, and trees), the principal of which is the Hevea Brasiliensis tree, native to Brazil. After the latex is processed, natural rubber becomes an elastomer with excellent mechanical properties. Natural Rubber has a typical service temperature range between –67° F and +180° F.
