Polyvinyl Chloride PVC -2 1.2 Bi-ProductsProducts and bi-products of PVC manufacture include Chlorine and Caustic Soda, two of perhaps the most important manufacturing "ingredients" not only for PVC manufacture, but many other applications. Chlorine is used in the manufacture of life-saving medication, indeed 85% of all pharmaceuticals. Caustic Soda too has many key, everyday applications, incl…

Carbon nanotube flame retardant A wide range of studies have shown that carbon nanotubes (CNTs) either single-walled (SWCNTs) or multi-walled (MWCNTs) are among the most promising alternatives for traditional flame retardants to be used in different polymers, such as, PP, PE, PLA, lignocellulose, epoxy resin.84-88 These studies have demonstrated that adding a small amount of well-dispersed CNTs (<5 wt%) to pol…

Bio based flame retardants In addition to inorganic fire retardants, certain plants have developed a defense mechanism against fire invasions due to their specific molecular structure. Bio based compounds in these plants owe their intrinsic fire retardancy to the formation of a thermally stable char layer when exposed to fire. A review of bio based flame retardants has been previously published by Costes …

Nanoclays flame retardant Nanoclays are ubiquitous nanofillers that are isolated from naturally occurring clays through energetic stirring, followed by centrifugation and freeze-drying, centrifugation and cross-flow filtration, or ultracentrifugation. Nanoclays are composed of stacked mineral silicates layers, forming complex clay crystallites. Three main mechanisms have been reported for fire retardancy…

Zinc oxide flame retardant Zinc oxide (ZnO) is one of the most popular photocatalyst metallic compounds because of its advantages, such as, cost efficiency, numerous active sites, high surface reactivity, and low environmental impacts. In fact, it is listed as safe by the US Food and Drug Administration given that zinc is an essential trace element. ZnO particles have high thermal conductivity as well as…

Nanosized fire retardants With the advent of nanotechnology in the past few decades, the prospects of nano scale fillers in polymer-based composites in the flame retardancy applications have progressed rapidly. Although nanofillers do not show excellent fire retardance inherently, incorporation of low amount of them in polymer composites tend to provide drastic improvement in thermal stability, smoke r…
