Green moves in plasticisers
Wherever you look in the plastics industry today, materials and additive suppliers are developing next-generation products based on renewable or recycled materials. With such a focus on sustain- able development, it should be no surprise that many of the latest innovations in PVC plasticisers also have a ‘green’ tint to them too. Swedish chemical company Perstorp is a typical
example. In recent years, it has significantly expanded its portfolio of ‘Pro-Environment’ products made from renewable and/or recycled raw materials. “Perstorp is continuing on its path to become finite material neutral and sees an increas- ing demand for bio-attributed plasticisers in the construction and automotive segments,” says Martin Hansson, who is the company’s Business Manager for C10 Plasticisers. The latest Perstorp innovation is Emoltene 100
Pro — a durable DPHP plasticiser based on renew- able materials. The first grade, launched in May of this year, contains 14% renewable content. A second grade with 71% renewable content will be available in the near future, the company says (for both grades, renewable content is determined to the mass balance concept which applies physical

and chemical traceability). Like Perstorp’s other renewable plasticiser,
Pevalen Pro polyol ester (introduced two years ago), Emoltene 100 Pro is ISCC PLUS certified. “Being ISCC PLUS certified means that our sustainable raw materials are ISCC compliant in all parts of the value chain back to the point of origin. On top of this, Perstorp has chosen both physical and chemical traceability throughout the value chain and trans- parency by GHG calculations,” says Hansson. “With the ongoing transformation of the construction industry shifting to more sustainable building standards, traceability equals credibility. For example, it is essential to provide reliable GHG
