Title
(EN) FIBER REINFORCED POLYURETHANE
(FR) POLYURETHANNE RENFORCE PAR DES FIBRES
Abstract
(EN)
This fiber reinforced polyurethane composition is a composite of a polyurethane produced by the condensation reaction of at least one isocyanate component and at least one polyol component and a blend of small fibers and long fibers. The small fibers are 1/4 inch in length or shorter and the long fibers have a length greater than 1/4 inch. The composite is especially useful in RRIM for interior automotive parts.
(FR)
La composition de polyuréthanne renforcé par des fibres est un composite produit par la réaction de condensation d'au moins un composant isocyanate et d'au moins un composant polyol et d'un mélange de petites et de longues fibres. Les petites fibres sont d'une longueur égale ou inférieure à 1/4 d'inch, et les longues sont de longueur supérieure à 1/4 d'inch. Le composite est particulièrement utilisé dans des systèmes de moulage par injection avec réaction (RRIM) pour des éléments intérieurs d'automobile.
