SBS791H-For modifed bitumen
SBS-791H is a linear triblock copolymer. Its S/B is 30/70. This product can be applied to the production of asphalt modification and asphalt waterproof rolls.
SBS-791H is used for asphalt modification, which can improve the low-temperature flexibility and high-temperature resistance to flow of asphalt. In other words, at 0℃ and below, SBS-791H can reduce the hardening, brittleness, and cracking of asphalt, which can improve the service life of highways. At 60℃, SBS-791H can increase the viscosity of asphalt and reduce the softening phenomenon of asphalt. This effect can improve the deformation resistance of asphalt pavement and protect traffic safety.
SBS-791H can improve the waterproof ability and tensile resistance of waterproof rolls. The waterproof roll material using SBS modified asphalt can be used between -25 ° C and 100 ° C, and the product life can reach over 20 years.
SBS-791H has a vast market. In China, this product has been used for road construction at Capital Airport, Yangtze River Bridge, and Shanghai Pudong Airport. In the international market, this product is popular in Russia, Türkiye, Vietnam and other countries, which has greatly helped the development of the local infrastructure industry and waterproof industry.
