Abstract

"ELASTÈMEROS DE POLIURETANO COM ALTA TEMPERATURA DE OPERAçãO". A invenção constitui-se de composições de poliuretano úteis em ambientes de operação de alta temperatura compreendendo: (A) i) um ou mais polióis tendo funcionalidade de hidroxila de 3,0 ou maior e uma média ponderal de peso molecular de 2.000 a 6.000, onde os polióis são o produto de reação de um ou mais iniciadores tendo uma funcionalidade média de 4 ou maior e um ou mais óxidos de alquileno; ou ii) a) um ou mais polióis tendo funcionalidade de hidroxila de 3,0 ou maior e média ponderal de peso molecular maior que 6.000, onde os polióis são o produto de reação de um ou mais iniciadores tendo uma funcionalidade média de 4 ou maior e um ou mais óxidos de alquileno, e b) um ou mais reticuladores tendo um peso equivalente de 200 ou menor; B) um isocianato orgânico; e C) um catalisador para a reação de um isocianato com um composto contendo hidrogênio ativo; onde a proporção de porções isocianato para porções contendo hidrogênio ativo é de 0,9:1,0 a 1,5:1,0. As composições da invenção podem ser processadas em temperaturas relativamente baixas para formar composições de alta temperatura de operação úteis como adesivos, vedantes, encapsulantes, gaxetas ou elastómeros. Estas formulações possuem viscosidades relativamente baixas em temperaturas ambientes e baixas. Além disso, as composições curadas da invenção demonstram a capacidade para suportar temperaturas de 140°C ou maiores e mais preferivelmente 155°C ou maiores sem deterioração significativa nas propriedades.
