Dynasol SolpreneĀ® 4302 Thermoplastic Rubber (SBS)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Styrenic TPE

Material Notes: Solprene 4302 is a linear block copolymer of styrene and butadiene, having 31% styrene content, most of it forming a polystyrene block, which gives the polymer a thermoplastic behavior. It has a non-staining antioxidant system; FDA approved, and is essentially gel free with a very clear color. It is presented as free flowing porous crumb making easy its handling and dissolution.

Uses: S-4302 is used as an ingredient for adhesives formulation, as an impact modifier for plastics and as an elastomeric modifier for asphalt mixtures used in paving and roofing.

Applications:
Adhesives
Polymer modification
Paving
Roofing
