Publication number: 20230340241Abstract: A recycled polymer composition is disclosed comprising: a) 80-99.5 wt. % of a post-consumer recycle polymer comprising a recycled high density polyethylene (PCR-HDPE) and a recycled polypropylene (PCR-PP); b) 0.5-20 wt. % of a styrenic block copolymer (SBC) having a block A derived from a vinyl aromatic monomer and a block B derived from a conjugated diene monomer; and c) 0-10 wt. % of at least an additive, based on total weight of the recycled polymer composition. An article obtained from the recycle polymer composition using extrusion blow molding (EBM) show improved mechanical properties including drop impact resistance and top load strengths.Type: ApplicationFiled: April 20, 2023Publication date: October 26, 2023Applicant: Kraton CorporationInventors: Freddy Vervoort, Lennaert Klerk, Stijn Van Averbeke, Laurens Engelen

Patent number: 10307983Abstract: Methods for forming a TPE-skinned composite include forming a skin layer having at least one surface and having a thermoplastic elastomer and an adhesive promoting agent; providing a foam layer; and forming the foam layer onto the said surface of the skin layer to form the TPE-skinned composite. Optional additives such as an organo-silane compound may be added to further improve the adhesion between the skin layer and the foam. The present disclosure also provides a TPE-skinned composite including a skin layer having a thermoplastic elastomer present in an amount of greater than 90 wt. %; and an adhesive promoting agent present in an amount of from 0.5 wt. % to 10 wt. % based upon the total weight of the skin layer.Type: GrantFiled: May 9, 2017Date of Patent: June 4, 2019Assignees: Kraton Polymers U.S. LLC, International Automotive Components Group North America, Inc.Inventors: Rose A. Ryntz, William J. Tansey, Matt Starling, Giachiano Bedogne, Freddy Vervoort
