This paper reviews three flexible PVC formulations using various types of alumina trihydrate (ATH) and magnesium hydroxide [Mg(OH) 2 ]. Smoke values are compared. In two of the formulations, Mg(OH) 2 has better smoke values than ATH; in a third formulation, ATH has better smoke values than Mg(OH) 2 . However, the third formulation uses an ATH with a very high surface area, which may indicate that smoke suppression may be a function of not only the type of flame retardants used but also surface area.
