Solprene® 4321

Technical Datasheet | Supplied by Dynasol

Discontinued : product no longer available

Linear block copolymer of styrene and butadiene. It contains 32% of styrene content and most of it forms polystyrene block which gives the polymer a thermoplastic behaviour. Offers high purity, non-staining antioxidant and clear color. The great advantage in the application of this copolymer rests on the fact that it does not require vulcanization to form a three-dimensional network. This guarantees the reinforced properties typical of chemically cross-linked rubber. It is an excellent modifier for asphalt applications including self adhesive roofing membrane and sealants. Solprene® 4321 is used in various applications like asphalt modification, compounding, non-woven (this segment includes industries such as: textiles, filtering, automotive and sanitary products), tapes, labels, footwear and transportation (includes both applications for the interior and the exterior parts of the vehicle).
