  • Publication number: 20240084124
    Abstract: Articles may be formed from a thermoformable composition, the thermoformable composition including: a) about 35 wt % to about 95 wt % of an acrylic pre-polymerized syrup; b) about 0 wt % to about 10 wt % of a comonomer; and c) about 5 wt % to about 65 wt % of a filler having an average particle size (d50) in a range of about 0.1 ?m to about 50 ?m; wherein the article has a surface having a gloss measurement at a 60° measurement angle within a range of about 0 Gloss Units to about 20 Gloss Units, and a roughness Ra within a range of about 1 microinch to about 100 microinches. Methods may include producing a thermoformed article by the steps of: i) preparing a thermoformable composition; ii) casting the thermoformable composition into a sheet; and iii) thermoforming the cast sheet against a mold to produce a thermoformed article.

  • Patent number: 10604647
    Abstract: A composition for making a cast, thermoformable sheet or slab, comprising: a syrup comprising: about 30-40% SSI—acrylic pre-polymerized syrup by weight at 20% solids; about 30-40% MMA—methyl methacrylate by weight; about 2-3% BA—Butyl acrylate by weight; about 1-15% by weight acrylic chips; and about 1-15% by weight rigid particles with a mean diameter of about 0.5-2000 ?m. The rigid particles may preferably comprise a polymeric material such as poly allyl diglycol carbonate particles. A method for producing a thermoformed article having a textured surface comprising mixing the syrup as above; swelling the acrylic chips; degassing the syrup; heating the syrup; casting the syrup into a sheet; and thermoforming the cast sheet against a mold.
