New SBCs from Kraton offer a PVC alternative
A new family of styrenic block copolymers (SBCs) from supplier Kraton Polymers LLC (Houston, TX) is halogen-free, recyclable, and FDA-approved for direct food-contact applications. Kraton says the new grades, sold under the Kraton A (“Advantaged”) brand, are designed to offer an alternative to flexible PVC in wire and cable, hoses, and sporting goods.
The first grade available is Kraton A1535, which can be compounded with TPUs to reduce hardness and enhance flexibility. According to Kraton, it offers dimensional stability, lower viscosity when compared to conventional grades, and weatherability.—[email protected]
