Title
(PT) elastômero de poliuretano sintático baseado em pré-polímero de segmento macio e catalisador sem mercúrio para uso em isolamento de tubulação submarina
Abstract
(PT)
elastômero de poliuretano sintático aseado em pré-polímero de segmento macio e catalisador sem mercúrio para uso em isolamento de tu ulação su marinaelastômeros de poliuretano sintáticos são preparados usando um catalisador desprovido de mercúrio. o elastômero é preparado a partir de uma mistura de reação contendo um pré-polímero preparado a partir de um poliéter poliol e um poli-isocianato, um extensor de cadeia, um poli-isocianato e microesferas. o elastômero adere bem a si próprio, o que o torno muito útil como isolamento térmico para as tubulações e outras estruturas que têm uma geometria com-plexa.
