Title
(EN) HOT MELT ADHESIVE BASED ON OLEFIN BLOCK COPOLYMERS
(FR) ADHÉSIF THERMOFUSIBLE À BASE DE COPOLYMÈRES SÉQUENCÉS D'OLÉFINES
Abstract
(EN)
A hot melt adhesive composition, comprising a blend of components including about 5-50% by weight of an olefin block copolymer, about 10-70% by weight of a first tackifying resin, about 0-65% of a second tackifying resin, about 0-60% by weight of a plasticizer; about 0-20% by weight of an aromatic reinforcing resin, about 0.1-5% by weight of a stabilizer, and about 1-40% by weight of a secondary polymer, the first and second tackifying resins and the reinforcing resin, having a crystallinity equal to or less than 250 Joules/gram, wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 mPa*s at 163 degrees C. Laminates, and methods of making such laminates using the hot melt adhesive are also described. The adhesive composition and/or laminate may be used in a variety of end products.

L'invention concerne une composition adhésive thermofusible, qui comprend un mélange de composants comprenant environ 5 à 50 % en poids d'un copolymère séquencé d'oléfines, environ 10 à 70 % en poids d'une première résine collante, environ 0 à 65 % en poids d'une seconde résine collante, environ 0 à 60 % en poids d'un plastifiant ; environ 0 à 20 % en poids d'une résine renforçante aromatique, environ 0,1 à 5 % en poids d'un stabilisateur et environ 1 à 40 % en poids d'un polymère secondaire, la première et la seconde résine collante et la résine renforçante ayant une cristallinité inférieure ou égale à 250 Joules/gramme, le total des composants étant de 100 % en poids de la composition et la viscosité de la composition étant inférieure ou égale à environ 20 000 mPa·s à 163°C. L'invention concerne également des stratifiés et des procédés de fabrication de tels stratifiés utilisant l'adhésif thermofusible. La composition adhésive et/ou le stratifié peuvent être utilisés dans divers produits finaux.
