Patent number: 10946627Abstract: The invention relates to a multilayered pultruded structure having a weatherable cap layer over a pultruded substrate, adhered with an appropriate tie layer. The structure provides improved weatherability and surface quality for pultruded structures. The invention is especially useful to provide a weatherable pultruded polyurethane, with an acrylic or styrenic cap layer. The weatherable polyurethane (PU) pultrusion of the invention provides an increased modulus over polyester pultrusions, making the weatherable PU pultrusion useful in commercial applications, and applications requiring a higher transverse modulus.Type: GrantFiled: April 8, 2015Date of Patent: March 16, 2021Assignee: Arkema FranceInventors: Thomas H.

Patent number: 10526464Abstract: The invention relates to small expanded polymer powder particles, and uses thereof. The expanded powder particles are formed by a non-melt process, resulting in individual expanded particles in the 5 to 100 micron range. The expanded powder particles are especially useful in cosmetic applications, as they provide a softer feel than a powder, and have a much higher surface area, making them highly absorbent for removing liquids and oils, as well as for use as excellent carriers and release agents for active ingredients.Type: GrantFiled: January 12, 2016Date of Patent: January 7, 2020Assignee: Arkema Inc.Inventors: Laurent B. Cartier, Stephen Serpe
