DOTP (DIOCTYL TEREPHTHALATE)

Product description

Dioctyl terephthalate (DOTP) is a phthalate-free polyvinyl chloride plasticiser. DOTP-based end products meet the highest environmental requirements. Unlike phthalate plasticisers, DOTP has no adverse effects on human health.


Application areas:

  • Floor coverings (PVC linoleums)

  • Roofing membranes

  • Cable compounds

  • Vinyl wallpaper

  • Food films

  • Artificial leather

  • PVC compounds and plastisols for FMCG



Part of SIBUR-Khimprom, SIBUR's Perm site, the 100 ktpa DOTP facility is being built under the licence from Aekyung Petrochemical, the world’s leading placticiser manufacturer. The launch is scheduled for 2Q 2019. SIBUR will produce DOTP from its own feedstock, to ensure seamless supplies and consistently high product quality.
