SBS

SBS polymers

Various types of polymers have been used to pure bitumen, including styrene-butadiene-styrene or SBS.

This polymer is one of the special additives for bitumen that extends the ideal temperature range of bitumen application, which increases the temperature of the softening point, decreases the degree of penetration, prevents cracking and separation of bitumen at very low temperatures and also increases the life span And the stability of bitumen.

But although this polymer has advantages in bitumen modify, its compatibility with bitumen is in fact the tendency to separate from bitumen during storage at high temperatures, which is a major barrier to the production of bitumen with improved properties.
