  • What is Diisobutyl phthalate (DIBP)?
  • Diisobutyl phthalate (DIBP) is a specialist plasticiser often used in combination with other high molecular weight phthalates. It is a fast fusing plasticiser which by itself it is too volatile for PVC applications. It is frequently used as a gelling aid in combination with other plasticisers.
  • What is Diisodecyl phthalate (DIDP)?
  • Diisodecyl phthalate (DIDP) is a common phthalate plasticiser, used primarily to soften Polyvinyl chloride (PVC). The typical content of DIDP in flexible PVC products is between 25 and 50% (w/w).
  • How is DEHP used in PVC manufacturing?
  • The main part of DEHP is added to PVC in different formulation and processing steps including calendering, extrusion, spread coating, and moulding. At EU level in total 341,000 tonnes was produced in 2007. A part of this was exported and around 291,000 tonnes DEHP was used for manufacturing processes in the EU in 2007.
  • How is DBP used in Denmark?
  • No detailed assessment of the use of DBP in Denmark exists. The use of DBP in chemical products (preparations) registered in the Danish product register is shown in Table 2.5. The total consumption of DBP in declared preparations has decreased from 320 tonnes/year in 2000 to 71 tonnes/year in 2004.
  • What is DIDP in flexible PVC?
  • The typical content of DIDP in flexible PVC products is between 25 and 50% (w/w). It has properties of volatility resistance, heat stability and electric insulation and is typically used as a plasticiser for heat-resistant electrical cords, leather for car interiors, and PVC flooring (ECPI, 2009).
  • What percentage of phthalate plasticisers were used in the 1990s?
  • In the early 1990s, DEHP represented about 51% of the total phthalate plasticiser market in Western Europe. Investigations of the historic use of phthalates in Denmark in different products shows that DEHP represented a major part of the phthalate use in the 1990's and was to a large extent replaced by DINP around 2000.
