Chapas de Policarbonato Compacto<\/strong><\/p>\n

O Policarbonato \u00e9 um material transparente com propriedades mec\u00e2nicas excelentes, estando entre os materiais de maior tenacidade. Sua resist\u00eancia a impactos \u00e9 dificilmente igualada por outro material, sendo talvez uma de suas mais marcantes propriedades.<\/p>\n

O Policarbonato () possui uma combina\u00e7\u00e3o \u00fanica de ductilidade, transpar\u00eancia \u00f3tica, rigidez e resist\u00eancia. O PC tamb\u00e9m apresenta excelentes propriedades el\u00e9tricas. O Policarbonato \u00e9 um pol\u00edmero amorfo e transparente.<\/p>\n
