SOLPRENE 4301 is a linear block copolymer of styrene and butadiene, having 33% of styrene content, most of it forming a polystyrene block, which gives the polymer a thermoplastic behavior. It is essentially gel free with a very clear color and has a nonstaining antioxidant system. It is BHT/TNPP free. Solprene 4301 is used as ingredient in adhesive formulations, as impact modifier for plastics and as elastomeric modifier for asphalt mixtures used in paving and roofing. It is presented as free flowing porous crumb making easy its handling and dissolution. APPLICATIONS: - Adhesives - Asphalt/Bitumen - Roofing - Compounding - Polymer modification
