  • Are phthalate esters a major class of PVC plasticizers?
  • Phthalate esters continue to represent the major class of PVC plasticizers as they have done for almost 70 years. The non-phthalate plasticizers are present in small amounts with very little distinction in market size among them. Table 28.2 includes an approximate distribution of global plasticizer consumption .
  • Which phosphate esters are used as plasticizers?
  • Today, the majority of the phosphate esters used as plasticizers are the alkyl diaryl phosphates, prepared with mixtures of various phenols and alcohols, often used in combination with GP plasticizers such as DINP or DIDP. Phosphate esters provide significant improvement in flame retarding properties and for some products, reduced smoke generation.
  • What are aliphatic dicarboxylic acid esters?
  • Aliphatic dicarboxylic acid esters are prepared by the esterification of diacids such as adipic or azelaic acid with C6 to C10 monohydric alcohols. This class of plasticizer is usually used to help extend the useful temperature range of plasticized PVC products, by providing increased flexibility at lower temperatures.
  • What is the Union Carbide retiree Corps?
  • The Carbide Retiree Corps, a retirement organization of former Union Carbide managers and scientists, compiled the materials from 1994 to 1999. The vast majority of this collection consists of narrative materials and photocopies of original documents that still exist within the Union Carbide Corporation archives Access restricted.
  • What percentage of plasticizers are phthalate esters?
  • Of perhaps more than 300 different plasticizers that went into some sort of commercial production or test marketing in the past 70 years, <20% were phthalate esters; the rest were non-phthalate plasticizers, a fact that is missed by many critics.
  • What was the first plasticizer used for PVC?
  • One of the very first plasticizers proposed for PVC was the phosphate ester, tricresyl phosphate. This plasticizer was later used for its flame-resistant properties in the first commercial PVC electrical wire insulation materials.
