Adhesion of ethylene-acrylic acid copolymers and their blends with paraffin to aluminium
The adhesion of four ethylene-acrylic acid (EAA) copolymers and of their blends with paraffin to aluminium has been measured by the T-peel test. The peel strength of EAA increased with the square of its acrylic acid content. For each EAA, the addition of paraffin first resulted in an increase of the peel strength up to a maximum when the failure switched from adhesional to cohesive. Two relationships were found between the peel strength of EAA-paraffin blends and the tensile strength of the blends: one valid in the case of adhesional failure and the other in the case of cohesive failure. Both allow very good prediction of the adhesion of EAA-paraffin blends to aluminium.
