- Effective fire retardation of polypropylene has traditionally relied on halogenated additives which have either been withdrawn or are under close scrutiny for their persistent, bio-accumulative and toxic properties. Achieving UL94 V-0 or LOIs approaching 30% while retaining the strength and toughness of polypropylene is very challenging. This work shows addition of just 1% organic-LDH can meet industrial demands for low flammability. In contrast to empirical studies showing enhanced fire retardant performance but without providing an explanation for the behaviour, this paper provides detailed insight into the two fire retardant mechanisms operating. This approach has been applied to 5 other polymers.
