MULTILAYER POLYMERIC ARTICLE HAVING A METALLIC VARIEGATED-LOOK

摘要

The invention relates to extruded polymeric sheet and articles with an appearance and a texture that can be varied to produce natural-looking variegated materials, that have a metallic or opalescent look. The appearance can simulate natural materials, such as granite, minerals, stone, metal ore. The extruded polymer sheet or article contains at least one polymer composite appearance layer having crosslinked polymer particles and metallic and/or pearlescent materials distributed in a thermoplastic matrix. The thermoplastic matrix can be pigmented or unpigmented. There extruded sheet or article has a transparent thermoplastic cap layer on the side facing the environment. The particle-containing layer can be coextruded in a multi-layer sheet that could include substrate layers and the cap layer.
