Petroleum resin effects as a tackifier, good softening agent and reinforcing agent for the compounds of natural and synthetic rubber, in particular to Styrene Butadiene Rubber (SBR).
· Improve the green tack and lower Mooney viscosity of compounding.
· Lower the hardness of compound after vulcanization, improve tensile and tear strength performance.
· Help in more uniform and even distribution with fillers.
· Improve rubber physical and mechanical properties such as tensile and wear strength, hardness.
