Plasticizers for polymers are either liquids with low volatility or solids. According to 2017 data, the total global market for plasticizers was 7.5 million metric tonnes. In North America the 2017 volume was ~1.01 million metric tonnes and in Europe the figure was 1.35 million metric tonnes, split between various end-use applications with a chemical type trend moving to higher molecular weight (HMW) orthophthalates and alternative types following regulatory issues concerning lower molecular weight (LMW) orthophthalates.
Almost 90% of polymer plasticizers, most commonly phthalate esters, are used in PVC, giving this material improved flexibility and durability.[1] Other polymers which can contain high loadings of plasticizers include acrylates and cellulose-type plastics, such as cellulose acetate, nitrocellulose and cellulose acetate butyrate.
