DOTP (DIOCTYL TEREPHTHALATE)
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 kta DOTP facility is being built under the license from Aekyung Petrochemical, the world’s leading plasticizers manufacturer. The launch was made in May 2019. SIBUR produce DOTP from its own feedstock, to ensure seamless supplies and consistently high product quality.
