Abstract

"FITA ADESIVA". Filmes úteis como forros de fita, e mais particularmente forros de filme de polipropileno biaxialmente estirado e fitas incluindo tais forros. Um filme de polipropileno biaxialmente estirado, quebradiço é proporcionado pela minimização da densidade de nucleação na folha vazada de polímero de polipropileno temperado e extrusado seguida pela maximização da taxa de crescimento esferulítico do polímero temperado resultante. A folha vazada assim formada é estirada em temperaturas maiores do que a normal nas subseq³entes etapas de orientação para a produção de filme de polipropileno biaxialmente estirado. Isto produz um filme mais quebradiço. A composição de polipropileno, a temperatura de extrusão, a temperatura do rolo de vazamento (isto é a temperatura de têmpera), e a temperatura de estiramento e outros parâmetros são selecionados de acordo com os ensinamentos aqui descritos de tal modo que o forro ou a fita resultantes possuam as seguintes propriedades preferidas, tomadas individualmente ou em qualquer combinação preferida: A) uma energia de tração na ruptura na MD de até cerca de 90 N-mm/mm^3 ^; B) um alongamento na ruptura na MD de pelo menos 70%. C) uma energia de punctura de até cerca de 130 N-mm; D) uma energia de dispensa de até cerca de 350 Ncm/cm^2 ^; E) quando dispensada sobre lâminas dispensadoras de metal ou de plástico serreadas comercialmente disponíveis, a borda serreada da fita ou do forro segue rigorosamente o contorno da lâmina dispensadora; e F) uma capacidade de ser rasgada à mão.
