Abstract

The invention relates to a stiffener (12) for a flexible pipe (10) manufactured from a polyurethane elastomer composition, which is obtained from a methylene diphenylene diisocyanate prepolymer composition (MDI prepolymer), which is then cross-Iinked with a polyamine in order to form the polyurethane elastomer composition suitable for being shaped such as to manufacture the stiffener.
