How C5 hydrocarbon resin enhances SBR Rubber Performance
Research on the use of C5 in styrene-butadiene rubber shows that the appropriate amount of C5 petroleum resin in SBR is 3-6 parts.
After adding C5 petroleum resin to the rubber material, the Mooney viscosity decreases with the increase of resin dosage, which is beneficial for the mixing, rolling, and extrusion of the rubber material.
The minimum torque (ML) and maximum torque (MH) of the rubber material decrease with the increase of resin. The decrease of ML is beneficial for improving the processing performance of the rubber material, while the decrease of MH indicates that it has an impact on the tensile stress of the rubber material.
The amount of resin used has no significant effect on the vulcanization characteristics of the rubber material (vulcanization speed, burning time, and resin dosage are not related) and the final performance of the product, with a slight decrease in hardness and 300% tensile stress.
