Patent number: 11353165Abstract: The invention relates to the use of branched aliphatic hydrocarbons such as squalane in compositions based on thermoplastic polymer, in particular on polycarbonate, which are used for producing molded parts used in LED lighting units, such as covers for instance. According to the invention it has been found that the use of branched aliphatic hydrocarbons makes it possible to enhance the total transmission and the transmission in the range from 360 to 460 nm, thus making corresponding compositions particularly suitable for producing molded parts for use in combination with white LED light sources. It has additionally been shown that yellowing and haze are simultaneously reduced.Type: GrantFiled: May 21, 2019Date of Patent: June 7, 2022Assignee: COVESTRO INTELLECTUAL PROPERTY GMBH & CO. KGInventors: Ulrich Blaschke, Alexander Meyer, Rafael Oser, Michael Roppel, Franky Bruynseels

Publication number: 20210221977Abstract: The invention relates to opaque colored multilayer articles having a substrate layer based on polycarbonate or polymethylmethacrylate. The compositions of the substrate layer contain a titanium dioxide having particular properties as white pigment. Compared to the Kronos® 2230 white pigment which is conventionally used as white pigment for corresponding compositions and has more particularly been specially matched to polycarbonate, it is possible to achieve considerably higher weathering stability of the colored shaped bodies provided that a UV absorber-containing coating has been applied to the substrate layer. Color stability and gloss are maintained even after weathering, and brilliant colors can thus be assured.Type: ApplicationFiled: May 27, 2019Publication date: July 22, 2021Inventors: Alexander MEYER, Joerg REICHENAUER, Ulrich BLASCHKE
