Abstract

enrijecedor para conduto flexível. a invenção refere-se a um enrijecedor (12) para conduto flexível (10) fabricado a partir de uma composição de elastômero de poliuretano, a qual é obtida a partir de uma composição de prepolímero de diisocianato de difenilmetano (prepolímero de mdi) que é depois reticulada com uma poliamina para formar a composição de elastômero de poliuretano apta a ser conformada para fabricar o enrijecedor.flexible conduit stiffener. The invention relates to a flexible conduit stiffener (12) made from a polyurethane elastomer composition which is obtained from a diphenylmethane diisocyanate (mdi prepolymer) prepolymer composition. It is then cross-linked with a polyamine to form the polyurethane elastomer composition capable of being formed to make the stiffener.
