Material Notes:
Solprene 1322 is a high molecular weight linear random -block styrene-butadiene copolymer with 30% styrene content, 22% present as a polystyrene block. It has a non-staining antioxidant system, FDA approved for use in food contact applications. It is a high purity polymer, essentially gel free with a very clear color. Solprene 1322 is used as an elastomeric impact modifier for plastics, especially in high gloss HIPS and ABS by the “in situ” polymerization process. It is available in bales wrapped in rubber-modified polystyrene film soluble in styrene monomer.Applications:Plastic modificationInformation provided by Dynasol
