INFLUENCE OF THE FIREPROOFING METHOD ON THE FIRE RETARDANT PERFORMANCE OF INTUMESCENT POLYPROPYLENE NONWOVEN

摘要

This study investigates different approaches to provide flame retardancy to PP nonwoven via intumescence. The traditional finishing method and the back-coating method are compared with the development of inherent fire retardant materials. The fire retardant properties are evaluated for various formulations. It is demonstrated that the performance of a system is closely linked with the fire proofing method. This study points out that, more than the active material used, the treatment method is another key issues to improve significantly the fire retardant properties of materials. The study of the intumescent process in the combustion conditions enables a better understanding of the fire retardant properties and allows us to propose appropriate solutions: "formulation versus fireproofing method".
