Thermoplastic acrylic sheet compositions and their use as substitutes for high pressure decorative laminate

摘要

A thermoplastic acrylic sheet and laminate formed therefrom are provided that allow the production of thin solid surfacing materials that provide the properties of conventional thicker solid surfacing with the advantages of processing and handling capabilities normally associated with high-pressure decorative laminate, wherein the thermoplastic acrylic sheet is formed from a thermoplastic acrylic polymer having dispersed therein a filler in an amount sufficient to provide the sheet with a Barcol hardness of at least 40; and an impact modifier; wherein the thermoplastic acrylic polymer has a melt flow index of at least 1.5; and wherein the filler has an aspect ratio of up to 25:1, and its use with an opaque cap layer in a laminate product.
