DISTRIBUTION OF MINOR PHASE COMPONENTS AND ITS INFLUENCE ON THE FILM-SUBSTRATE INTERFACE IN FILM INSERT MOLDINGS

摘要

In most cases, the injection molding conditions significantly affect the morphology and subsequently the bulk mechanical properties of the product. This effect is more pronounced when polymer blends or composites are used where the extent of dispersion and orientation of the disperse phases or reinforcements would affect the final property of the molding. In film insert moldings, it is important to ensure that the film is firmly attached to the substrate. Hence, the distribution of the disperse phases (Acrylonitrile-butadiene-styrene in polycarbonate) at the interface is investigated to establish correlations between phase anisotropy, film-substrate adhesion and bulk mechanical properties.
