Abstract

"GAXETA ENROLADA EM ESPIRAL E PROCESSO PARA PRODUZIR UMA TIRA DE VEDAçãO PARA UMA GAXETA E PARA FABRICAR UMA GAXETA". Descreve-se uma gaxeta enrolada em espiral. A gaxeta inclui uma tira de vedação (11) enrolada em uma espiral e uma tira de suporte (10) enrolada em uma espiral de tal modo que a espiral da tira de vedação é formada interposta entre as voltas da tira de suporte. A tira de suporte compreende um material resiliente, o material resiliente compreendendo um componente CEV em uma proporção de, pelo menos, 25% p/p da tira de vedação. O componente CEV é pelo menos parcialmente derivado de CEV seco, e a tira de vedação não inclui uma tira de veículo em um aspecto. Em outro, aspecto, o componente CEV é, pelo menos, parcialmente derivado de CEV seco, e a tira de vedação tem um nível de umidade de entre 3-20% p/p do material resiliente de tira de vedação durante o enrolamento na referida gaxeta. Um processo para produzir uma tira de vedação é também descrito.
