Abstract

composto de borracha reforçado. a invenção reivindicada se refere ao desenvolvimento de receitas de borracha para melhorar as propriedades essenciais relacionadas a compostos de borracha correlacionados. a sílica gel é adicionada ao composto de borracha como agente de reforço, substituindo parcialmente parte da sílica precipitada. o uso de sílica gel para o mercado pneumático provê maior resistência ao rasgo, alongamento e desempenho de adesão, além de melhorar a adesão do pneu em superfícies molhadas.
