Abstract

composição de poliolefina, artigo, e, membrana de chapa. trata-se de uma composição de poliolefina útil para produzir membranas de chapa, bem como outros artigos de fabricação. a poliolefina em composição combina uma termoplástica produzida em reator (rtpo) com pelo menos um polietileno linear de baixa densidade (pelbd) para melhorar a contração de molde e a força de expansão térmica em comparação com uma composição somente rtpo, sem afetar outras propriedades.
