  • What are phthalate plasticizers?
  • From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
  • What are phthalates and how do they work?
  • Phthalates are a large class of organic molecules of the family of plasticizers, agents that intercalate in the chemical structure of macromolecules such as PVC which give the material the typical properties of the plastic substances.
  • How to choose phthalate replacement?
  • The choice of phthalate replacement is usually based on several criteria like: Expected exposure conditions of finished product during its service life. These include compatibility, outdoor weatherability, low-temperature flexibility, etc. The type of plasticizers which can be used to overcome these issues are listed below.
  • What are the benefits and limitations of phthalate plasticizers?
  • Key benefits and limitations of phthalate plasticizers include: Di-2-ethylhexyl-phthalate (DEHP) is a low molecular weight ortho-phthalate. It has a chemical formula of C 6 H 4 (C 8 H 17 COO) 2. It is produced by the esterification of phthalic anhydride with 2-ethyl-hexanol.
  • Which phthalate is used as a plasticizer for PVC?
  • DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
  • What chemicals are used in tire production?
  • Several studies reported a variety of chemicals are used with tire production, including 2- [ (4-methylpentan-2-yl)amino]-5- (phenylamino)cyclohexa-2,5-diene-1,4-dione (6PPD-q), dimethyl phthalate (DMP), and diphenyl guanidine (DPG).
