Title (EN) LENS BLOCKING MATERIAL COMPOSITION
(FR) COMPOSITION DE MATERIAU D'ADHERENCE POUR LENTILLES DE CONTACT
Abstract:
(EN) A lens blocking material composition contains 80-90 weight percent of an ethylene derived hydrocarbon polymer, 10-15 weight percent of a thermoplastic aliphatic hydrocarbon resin and 1-3 weight percent of an ethylene/vinylacetate copolymer.
(FR) Une composition de matériau d'adhérence pour lentilles contient de 80 à 90 % en poids d'un polymère d'hydrocarbure dérivé d'éthylène, de 10 à 15 % en poids d'une résine d'hydrocarbure aliphatique thermoplastique et de 1 à 3 % en poids d'un copolymère d'éthylène/vinylacétate.
