  Product Introduction(DOTP)

  Dioctyl terephthalate is an excellent primary plasticizer for PVC. The most popular replacement for DOP. It is colorless and odorless viscous liquid, soluble in oil but not in water.

   

  · 

  Has good compatibility, can be used as a plasticizer for PVC, acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc.

  · 

  · 

  Some of the applications where DOTP is used, include films& sheets, coated fabric, flooring, wall coverings, and wires and cables.

  · 

  · 

  Also can be used as synthetic rubber and artificial leather plasticizer, paints and coatings additive, precision instruments lubricant, lubricant additive, and paper and rubber softener.

  · 

  · 

  Can be safely used in toys and childcare articles, beverage packaging and medical devices since it does not contain phthalates.
