Property Requirements of Vulcanized Rubber

6 Property Requirements of Vulcanized Rubber 2.6.1 Stress-strain Properties 

Tensile strength, modulus at a given elongation and elongation at break depend on the rubber type and the reinforcing filler type and 

This depends on total filler loading the higher the loading, the higher the hardness. Softener loading reduces hardness. 

This property depends on filler particle size and filler loading. Higher filler loading gives lower resilience. Rubber type plays a great role here in that no synthetic rubber can match the characteristic of high resilience of natural rubber. 

It is similar to tensile strength from the compounding point of view. Fillers such as silica improve tear strength.
