Representatives of various industries [17] have examined some smoke depressants and flame retardant resins introduced by various US Companies in relation to US legislation. These include smoke suppressed polyvinylchloride (PVC) (BE Goodrich) and polyurethane (PU) foams (Mobay Chemical), and smoke suppressant additives from Climax Molybdenum, and Sherwin-Williams (molybdenum compounds), Solem Industries, and Alcoa Chemicals (aluminium trihydrates, for polypropylene (PP) and PVC), Dover Chemical Corp., (aromatic bromine compound for PP), and US Borax (zinc borate). 

Aluminum trihydrate is available in a variety of grades that differ in particle size, color, and surface treatment. ATH finds use in such resins as polyesters, epoxies, and polyvinyl chloride (PVC). Commercial manufacturers of ATH include Akochan Corp. Alcoa Industrial Chemicals Pluess-Staufer International Inc. and Whittaker, Clark Daniels.
