Abstract
"processo para a produção de pvc expandido,mistura polimérica inicial,material plástico expandido com base em pvc,e ,produto feito de pvc expandido.um processo para a produção de pvc expandido do tipo que compreende o aquecimento de uma massa de mistura polimérica (13)dentro de um molde fechado ,dito processo incluindo:(a) controle da expansão de dita massa (13) devido ao processo de moldagem a quente no ambiente tendo um volume constante definido pelo molde fechado mencionado (10),dito controle sendo realizado pela presença,na massa mencionada de mistura polimérica (13) ,de micropartículas (16) de material compressível,adequadas para serm contraídas ,sob a ação da pressão gerada pelas formação e expansão de microcélulas (20) de gás expandindo dentro da mesma massa (13) ,desde uma forma inicial (a) tendo um volume maior ,para uma forma (b) tendo um volume menor ;e (b) tendo volume menor;(b) a expansão das micropartículas mencionadas (16) contidas dentro da massa do material expandido moldado,desde a configuração delas (b) para a configuração inicial (a) com um volume maior ,a densidade de dito material expandido assim obtido sendo determinada pela presença simultânea ,dentro da massa (13c) do último,de ambas as microcélulas (2) do gás expandido e as micropartículas mencionadas (16) na configuração delas a tendo um volume maior .com relação á técnica conhecida para a produção de materias plásticos expandidos , o processo da invenção não apenas evitar a formação de perdas de massa fundida durante o processo de moldagem ,mas também permite que seja obtido um pvc expandido tendo o valor de densidade desejado ,mesmo usando quantidades muito menores de agentes de expansão em comparação com aquelas utilizadas em processos atuais deste tipo.
