Abstract

Patente de Invenção: <B>"FOLHAS DE POLICARBONATO OPTICAMENTE ISOTRóPICAS, BEM COMO PROCESSOS PARA SUA PRODUçãO"<D>. Materiais de fundição injetada de policarbonato podem ser processados para folhas opticamente isotrópicas em um processo de extrusão de "chill-roll". As folhas opticamente isotrópicas são usadas como folhas de cobertura para proteção contra arranhamento de suportes de dados (CD-ROMS), ou são usadas, elas próprias, como materiais de suporte para a camada de informações.
