Sažetak
The basis in the production of elastomeric materials is rubber which becomes cured during crosslinking process. Curing is a chemical-physical modification in which mostly plastic rubber transfers to rubber-elastic state. The curing process requires a curing agent, most frequently sulphur, and the process is performed at higher temperatures for several hours. The type of the used rubber defines the basic properties of product, for example: stability, ageing and flexibility at lower temperatures, as well as strength and elasticity. The paper presents the study of influence of crosslinking temperature and crosslinking time on some mechanical properties of natural rubber and styrene/butadiene rubber.
