Metal hydroxides for flame retardant wire and cable compounds
This paper discusses use of metal hydroxides such as aluminium trihydroxide (ATH) and magnesium hydroxide (MDH) as flame retardant additives for wire and cable compound applications. Effects of particle size and particle surface area of the flame retardant on resulting compound performance are studied. The effect of metal hydroxide loading levels on the performance balance of flame retardancy versus physical properties is also investigated. Surface modification of the metal hydroxide additives is also studied and found to help enhance compound performance markedly. Use of properly surface-modified ATH or MDH was shown to provide favorable process rheology and enhanced fire performance but not necessarily always in the same direction of goodness. The choice of surface modification needs to be considered in a way to maximize overall compound performance. The results also showed that high-performance flame retardant compounds can be achieved by using cost-effective metal hydroxides along with appropriate polymers when a uniform compound is assured by optimal flame retardant polymer compatibilization.
