Abstract
(EN)
A composition containing a thermoplastic elastomer and fine elastic particles is extruded in the shape of a sheet from an extruder, and this sheet type material is extended, whereby a skin material having minute recesses and projections, which occur due to the fine elastic particles, in and on a surface thereof is produced. This skin material may have a bonding agent layer, a substrate layer or a resin foam layer laminated on the surface thereof which is on the opposite side of such an apparently delustered surface thereof. Such a skin material can be manufactured with a high productivity without causing any environmental problems concerning a solvent to occur. When a molding operation is carried out by using this skin material, a molded product having an apparently delustered surface is obtained.
(FR)
Une composition contenant un élastomère thermoplastique et de fines particules élastiques est extrudée, au moyen d'une extrudeuse, sous la forme d'une feuille qui est ensuite étirée, de façon à former un matériau de revêtement extérieur dont la surface est pourvue de minuscules creux et saillies qui résultent de la présence des fines particules élastiques. Le matériau de revêtement extérieur peut comprendre une couche d'agent adhésif, une couche de support ou une couche de mousse de résine, qui est appliquée sur la surface qui se trouve sur le côté opposé à la surface d'apparence mate dudit matériau. On peut fabriquer un tel matériau de revêtement extérieur avec une productivité élevée sans risques pour l'environnement dûs à la présence d'un solvant. Lorsque l'on effectue une opération de moulage au moyen d'un tel matériau de revêtement extérieur, on obtient un produit moulé présentant une surface d'apparence mate.
