Poly(vinyl chloride) (PVC), is basically plasticized by low molecular mass esters such as dioctyl phthalate (DOP), dioctyl sebacate (DOS), etc.
Industrial plasticizers dioctyl phthalate (DOP) and dioctyl sebacate (DOS) were commercial products of Suzran Industrial Co.
Ortho/para toluene sulfonamide and dioctyl sebacate plasticizers.
Series B is an optimization of the VA content, based on series A, with a simpler anti-aging package, the use of higher surface area aluminum hydroxide (ATH) and an elevated plasticizer level (a mixture of DOS, dioctyl sebacate and TOTM, trioctyl-mellitate).

Attempts to use conventional linear dibasic acid esters (such as dioctyl adipate, dioctyl sebacate and di-2-ethylhexyl sebacate) or phthalate esters (such as di-2-ethylhexyl phthalate) have also been unsuccessful, since such conventional ester plasticizers are either incompatible with the elastomer, resulting in exudation of the plasticizer, or are too volatile for many elastomer uses.
