Abstract

resumo “enrijecedor à flexão, método para preparar uma luva de enrijecedor à flexão flexível e método para ligar um cano flexível” um enrijecedor à flexão que compreende: (i) uma luva polimérica flexível tendo um orifício axial para receber um membro flexível alongado e (ii) meios de ligação para ligar a luva a um suporte. pelo menos uma porção da luva polimérica flexível é um elastômero de poliuretano produzido em uma reação de um pré-polímero com terminação isocianato e um agente de cura a um índice de isocianato de 90 a 120. o pré-polímero com terminação isocianato tem um teor de isocianato de 7 a 15% em peso, sendo um produto de reação de pelo menos um poliisocianato aromático e pelo menos um poliéter poliol tendo um peso equivalente de hidroxila de 350 a 2000 e uma funcionalidade nominal de 2 a 2,3. o agente de cura é um ou mais extensores de cadeia tendo um peso equivalente por grupo reativo com isocianato de até 125 ou uma mistura contendo um ou mais desses extensores de cadeia e um ou mais poliéter polióis tendo um peso equivalente de hidroxila de 350 a 2000 e uma funcionalidade nominal de 2 a 2,3. o teor de segmento duro do elastômero de poliuretano tem de 40 a 60% em peso.
