Evaluation of the mechanical strength of an intercalary film, e.g. plastic film used in laminated glazing, involves evaluating its resistance to tearing and its adhesion to a glass type substrate

摘要

The evaluation of the mechanical strength of an intercalary film, such as a polymer film, consists of evaluating its resistance to tearing and equally evaluating the adhesion of the intercalary layer with respect to at least one glass type substrate. Independent claims are also included for: (a) a polymer film with acoustic insulation properties destined to be tested by this method; (b) a laminated glazing incorporating at least two glass type substrates and at least one polymer film.
