Co-extrudable adhesives with good age-down resistance |
摘要 |
Co-extrudable adhesive compositions which have excellent adhesion, and which bond well to ionomers, even after long aging, are formed by blending polyethylene with a very low density of 0.86 to 0.91 with polyethylene having a density of 0.91 to 0.935, together with a hydrocarbon elastomer. Acid grafting of any of the components is preferably present. More than an insubstantial amount of polyethylene with higher density than 0.935 is deleterious to initial or age-down peel strength of the adhesive ionomer bond, and is not part of the adhesive composition.
