VESTENAMER® in rubber compounds - Additive for the rubber
VESTENAMER® has an influence on the physical properties of the cured compounds . In general, hardness and modulus are increased, whereas tensile strength, strain at break and tear resistance are slightly decreased. For the most part, the dynamic properties are also improved, as demonstrated by the reduced heat buildup in fatigue tests.

COMPARING STRENGTH PROPERTIES OF NATURAL AND SYNTHETIC
The properties of natural rubber mixtures are the followings: - high static tensile strength (15-22 MPa), - high elongation (600-900%), - excellent elasticity at low temperature (up to – 10 0C doesn’t change substantially) - poor ozone and degradation stability, - good confectionability because of excellent crude adhesion.

Natural Rubber (NR)
Natural Rubber (NR): Natural rubber is the prototype of all elastomers. It is extracted in the form of latex from the bark of the Hevea tree. The rubber is collected from the latex in a series of steps involving preservation, concentration, coagulation, dewatering, drying, cleaning, and blending. Because of its

General Properties of Elastomers
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.
