Linear Styrene-Butadiene-Styrene SBS Rubber Sibur SBS L 7342
Description
This linear styrene-butadiene thermoplastic elastomer is the product of block copolymerization of styrene and butadiene in a hydrocarbon solution in the presence of an organolithium catalyst. SBS L 7342 is dusted with calcium stearate, zinc stearate or silicon dioxide. Stabilized with non-staining antioxidants.
Applications:
Road construction, glues, sealants, adhesives, compounding, plastics modification.
