Flame retardants synergisms involving halogens

The following sections concern the use of a chlorinated flame retardant (CFR) in plastics. CFR consists of the Diels-Alder adduct of hexachloro-cyclopentadiene and 1,5-cyclo-octadiene. Some experimental results are given, without the proposal of any mecharusms, which exemplify the flame retardancy improvements obtainable by various synergistic combinations. [Pg.327]

ALTERNATE SYNERGISTS FOR USE WITH HALOGEN FLAME RETARDANTS [Pg.327]

The synergist antimony oxide has been used in combination with halo-genated flame retardants for years to impart flame retardancy to plastics [1]. Today, many highly efficient antimony oxide/halogen systems are used to give flame retardancy properties to a wide variety of polymers. Complete or partial substitutes for antimony oxide in certain polymers have been reported [2] they are ferric oxide, zinc oxide, zinc borate and zinc stannate. Most of these synergists are effective with polyamides and epoxies when using a chlorinated flame retardant. [Pg.327]

The chlorinated flame retardant, CFR (see introductory paragraph above for chemical composition), can also be used in nylons, epoxies and polybutylene terephthalate (PBT) to achieve flame retardancy using [Pg.327]
