Interspersal Inc.

Recently, a polymer compounder asked for our help in a difficult situation: The graftable hindered amine light stabilizer (HALS) that they were using in a critical application was being discontinued by the legacy manufacturer. Our team sprung into action. Leveraging our supply chain capabilities, we collaborated with one of our manufacturing partners to develop a chemically-equivalent alternative. Within four weeks, we provided a sample that surpassed expectations in initial trials. As production scales up, our customer is relieved to avoid a complete reformulation – saving time, money, and resources. Introducing SPERSESTAB™ 5031, the newest member of our HALS line. Need a dependable partner in your additives supply chain? Let's connect and ensure smooth sailing ahead. #Interspersal #SupplyChainSolutions #PolymerAdditives

SPERSESTAB™ 3281: UV stabilization with sustainability in mind. Benzotriazole UV absorbers have long been essential light stabilizers for plastics, coatings, candles, adhesives, and other substrates. Recently, these additives have come under regulatory scrutiny. In Europe, UV-328, UV-326, UV-329, and others have been designated Substances of Very High Concern under REACH. There is also pressure for phase-out in the automotive industry, where many standard products (UV-328, UV-326, UV-329, UV-234, UV-P) have been added to the Global Automotive Declarable Substances List (GADSL). SPERSESTAB™ 3281 is a unique benzotriazole UV absorber that has been affirmed as not PBT/vPvB in evaluations by an EU member state, and is not GADSL listed. Besides these regulatory advantages, it is designed to deliver performance comparable to industry standards like UV-328, UV-329, and UV-234 to ensure optimal UV protection while maintaining compatibility with a wide range of materials. Plus, its versatility extends beyond plastics to applications like candles and adhesives. Join us in the movement towards eco-conscious UV stabilization. Choose SPERSESTAB™ 3281 for your next project and embrace sustainability without compromising performance.
