The Influence of the Colloidal Structure of Polymer Blends on the Adhesion Strength of Polyolefin Compositions.

The way an adhesive composition peels depends on the competing influences of its physical and mechanical properties and the reduced acidity parameter of the polymer, which forms a continuous phase. In practice, this can mean that on the outside insulation of steel pipes “dilution” of the expensive adhesive, usually a double or triple ethylene copolymer, by the less expensive polyethylene is possible, in a ratio that provides a continuous phase of “adhesion active” components. Considering the large difference in price and the fact that, in Russia, all high-quality adhesive ethylene copolymers are imported, such dilution could be an economically attractive approach.
