POLYSTYRENE-B-POLYBUTADIENE-B-POLYSTYRENE Description and Usage
Performance
SBR-1500 is the most typical type of general-purpose contaminated
soft styrene-butadiene rubber. The adhesiveness and processing
properties of raw rubber are excellent. The wear resistance, tensile
strength, tear strength and aging resistance of vulcanized rubber are
better. SBR-1502 is the most typical type of general non-polluting soft
styrene butadiene rubber. Its performance is equivalent to that of
SBR-1500. It has good tensile strength, wear resistance and flexural
energy.
Usage
SBR-1500 is widely used in carbon black as a reinforcing agent and
products with low color requirements, such as tire tread, retread tread,
conveyor belt, hose, molded products and extruded products. SBR-1502 is
widely used in bright and light colored rubber products such as tire
sidewalls, transparent rubber shoes, tapes, medical products and other
general colored products.
