Permanent discolorations of sheet flooring, and other appearance surfaces made from flexible PVC, are commonly called stains. Resistance to stains is imparted to such surfaces through a four part mechanism which relates directly to plasticizer composition. Benzoate esters of 2,2,4‐trimethyl‐1, 3‐pentanediol have traditionally been used as stain resistant plasticizers, but are available commercially only as complex mixtures with reaction by‐products. New products, which are high purity and chemically similar, are shown to have performance attributes. Stain resistance and volatility are improved by the use of high purity derviatives.
