Overview:
SBR1500 is a non-oil extended SBR, and it is produced through emulsion polymerization of butadiene and styrene at low temperature with redox polymerization initiators. The main process includes free radical emulsion copolymerization, intermingle, agglomeration, etc. Compared with natural rubber, proper compounding is expected to give SBR higher resistance to abrasion, heat, aging, ozone, and water. SBR also provides excellent uniformity and airtight capability. SBR can mix with natural rubber with any proportion to produce rubber.
