  • Although commercially available chemical protective clothing can resist a wide range of chemicals, there is still a need to further improve the chemical resistance, as well as the elasticity and flexibility, currently reduced by the incorporation of thermoplastics in those products. This work aims to fabricate a new multilayer elastomeric laminate from fluoroelastomer, nitrile rubber, and butyl rubber, which can overcome the current limitations of resistance, elasticity, and flexibility. The natural adhesion between these elastomers is poor due to their different chemical and mechanical properties. In this work, the use of a compatiblizing layer of rubber blends is introduced, specifically, a layer of fluoroelastomer/nitrile rubber (blend 1) and a layer of nitrile rubber/butyl rubber (blend 2) between the individual rubber layers to form a five-layer laminate. T-peel tests were conducted after vulcanization for each laminate pair: a) fluoroelastomer and blend 1, b) blend 1 and nitrile rubber, c) nitrile rubber and blend 2, as well as d) blend 2 and butyl rubber. This approach improved the T-peel strength.
