Cure Adhesion in the Interface of Fluorinated and Nitrile Rubbers

Abstract

Abstract Recently there has been a great deal of interest in new composite rubbery materials. Good properties require the reinforcement of the interfacial region which is formed between different rubbers. In order to strengthen the interfacial region, it is necessary to increase the thickness of the interfacial layer and the intermolecular forces. However, in a laminate and blends of rubbers with physically and chemically different properties, it is often very difficult to obtain this as, for example, in the case of fluorinated (FR) and nitrile (NBR) rubbers. This work indicates newly developed vulcanization systems which are very effective in producing FR-NBR composite materials with very good properties, because they induce interpolymer interactions.
