The product, made from selected naphthene-base crude from South America and the Middle East, boasts low viscosity, good compatibility, excellent four fractions, and high bonding strength, besides being not liable to brittle fracture at -29℃.Compared with common waterproof asphalt products, the product enables downstream enterprises to save energy and reduce consumption by reducing the sheet production temperature by 10℃. With insight into the needs of the customers in the waterproofing industry, we have taken the lead in the industry by publishing “Low-Viscosity Flexible Asphalt”, the first enterprise standard in China, and launching low-viscosity flexible asphalt products.
