Solprene® 4302

Solprene 4302 is a linear block copolymer of styrene and butadiene, having 31% of 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.

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.

It is presented as free flowing porous crumb making easy its handling and dissolution.
