Abstract

"PROCESSO PARA ROTOMOLDAGEM DE UMA PEçA" Uma camada de espuma é formada por rotomoldagem em uma etapa de aquecimento do polímero espumante que é interrompida antes que a temperatura de espumação seja atingída: o processo de baseia na inércia térmica do sistema composto também pela fórma (1) e pelas camadas já colocadas para completar o aquecimento, sem que ele atinja todavia uma intensidade que provoque uma espumação desordenada. A camada de espuma é regular e aderente. As camadas densas que envolvem a camada de espuma podem ser diferentes.
