Dynasol Solprene® 4316 Thermoplastic Rubber (SBS)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Styrenic TPE

Material Notes: Solprene 4316 is a radial styrene/butadiene block copolymer with 30% styrene content, most of it forming a polystyrenes block which gives the polymer a thermoplastic behavior. It develops properties of vulcanized rubber yet not requiring vulcanization. It is protected with a non staining antioxidant system; FDA approved, suitable for food contact applications and is essentially gel free with a very clear color. It is available as free flowing porous crumb for easy handling and dissolution, packaged in standard paper bags, super sacs and cardboard boxes

Uses: Solprene 4316 is used as elastomeric modifier for asphalt and plastics, as ingredient of soling formulations and as base for pressure sensitive adhesives.

Main Applications:
Paving
Polymer modification
Adhesives

Footwear
