What is modified SBS bitumen?
Many customers who purchase SBS modified bitumen waterproof membrane machine are very interested in this question. Today, I will explain in detail what modified SBS bitumen is. SBS modified bitumen used in SBS modified bitumen waterproof membrane machine is made by adding SBS (styrene-butadiene-styrene block copolymer) as a modifier to ordinary bitumen. After a certain process of modification and mixing, it becomes a bitumen material.
SBS itself is an elastomer material. After being mixed with bitumen, its structure is changed, but this structure compensates for the performance defects of bitumen, making it more elastic and tough.
Well-modified SBS bitumen from SBS modified bitumen waterproof membrane machine has more stable performance at high temperatures, and it is less prone to flowing even in summer, greatly reducing road indentations.
It is also suitable for environments with large temperature differences, is less prone to tearing in winter, has improved anti-aging ability, and thus increases the lifespan of the road surface. Its adhesion is also more stable.
