牌号简介 About |
---|
Solprene® 416是一种具有30%苯乙烯含量的径向苯乙烯/丁二烯嵌段共聚物,其中大部分形成聚苯乙烯嵌段,使聚合物具有热塑性行为。它发展了硫化橡胶的性能,但不需要硫化。它是用一种不染色的抗氧化系统来保护的;FDA批准的,适用于食品接触应用,并且基本上是无凝胶的,具有非常清晰的颜色。Solprene® 416用作沥青和塑料的弹性改性剂、溶胶配方的成分和压敏粘合剂的基料。它是自由流动的多孔碎屑,易于处理和溶解,包装在标准纸袋,超级囊和纸板箱。 Solprene 416 is a radial styrene/butadiene block copolymer having 30% of 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. Solprene 416 is used as elastomeric modifier for asphalt and plastics, as ingredient of soling formulations and as base for pressure sensitive adhesives. It is available as free flowing porous crumb for easy handling and dissolution, packaged in standard paper bags, super sacs and cardboard boxes. |
