Deformation behavior of rubber blends investigated by a new real time spectral birefringence system
Rubber compounds used in tires usually contain blends of more than one rubber to synergistically combine the properties of these rubbers. These include styrene-butadiene (SBR) and butadiene (BR) rubber or blends of natural rubber (NR) and butadiene rubber. In this study we investigated the true-stress true-strain birefringence behavior of blend of SBR and BR with a new real time spectral birefringence system and obtained the stress optical constant for the SBR/BR blends covering 10-40% BR concentration. The stress optical constants were found to decrease with the increase of BR concentration.
