Title (EN) ELASTOMERIC LAMINATES WITH MICROTEXTURED SKIN LAYERS
(FR) STRATIFIES ELASTOMERES A COUCHES DE PEAU MICROTEXTUREES
Abstract:
(EN) Microtextured elastomeric laminates (1) comprising at least one elastomeric layer (3) and at least one thin skin layer (2, 4) is preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate to recover.
(FR) On prépare des stratifiés élastomères microtexturés (1) comprenant au moins une couche élastomère (3) et au moins une couche mince de peau (2, 4), de préférence, en coextrudant les couches après étirement du stratifié au-delà de la limite élastique des couches de peau, et en laissant le stratifié récupérer.
