MATERIALS | PVC PLASTICISERS
late polyol ester plasticiser PETV (pentaerythritol tetravalerate) branded as Pevalen, is now preparing for the launch of Pevalen Pro, which is based on partly renewable raw materials. Pevalen Pro will be made available during Q4 2019. Jenny Klevås, Global Marketing & Product
Manager, says that while Emoltene is intended for outdoor applications exposed to tough conditions, including automotive exteriors, cables and roofing, Pevalen is suitable for close-to-human roles such as coated fabrics, flooring, food contact applications and gym products. “With Pevalen Pro we will be able to offer a superior non-phthalate plasticiser that can boost the environmental profile for flexible PVC, something that we truly believe is the right way forward,” she says. Pevalen Pro will be available with up to 40%
renewable content as a first step, based on the mass balanced production concept. This involves mixing fossil-based raw materials and renewables but keeping track of their quantities and allocating them to specific products. “We believe that using the mass balance concept is the best approach to be able to make the production economically feasible,” says Klevås. The product will be ISCC (
www.iscc-system. org) certified, guaranteeing that the bio-based input is sustainably sourced. The certification also includes carbon footprint calculations. Perstorp recently initiated a feasibility study

investigating the possibility to recycle methanol, one of the ingredients used for producing Pevalen. The project, partly funded by the Swedish Energy Agency, involves construction of a new plant, the integration of raw materials, fuel, energy and residual streams and new logistical solutions for the methanol. Proviron continues its focus on its phthalate-free bio-based products. “Over the last decade, Proviron noticed sufficiently diversified requests to justify the development of two general-purpose and two niche plasticisers,” says Koen Engelen. The company now offers a valerate plasticiser and what it calls an “upgraded epoxidised”

plasticiser. The valerate plasticiser is intended for applications where weatherability and hydrolytic stability are critical. The upgraded epoxidised plasticiser is pitched for indoor applications “where biobased sourcing is seen as a marketing tool and a way to secure the supply,” Engelen says. “In fact, besides being renewable, this epoxidised plasti- ciser delivers outstanding long-term stability and eases recycling.”
Regulatory update Alongside the new production introductions, the regulatory picture for the plasticiser industry also continues to develop. In July, the European Chemicals Agency (ECHA) confirmed industry expectations by announcing that it had submitted a recommendation to the European Commission to amend Authorisation List (Annex XIV of REACH) entries by adding endocrine disrupting properties of DEHP, BBP, DBP, and DIBP. Once the Commission decides on the amendment, some previously exempted uses (notably medical devices and food contact materials) will require authorisation. ECHA also recommends that the exemption for uses of DEHP in immediate packaging of medicinal products be removed from the Authorisation List. European Plasticisers, the trade association
representing plasticiser manufacturers in Europe, responded to the ECHA recommendations in mid-July. It said that: “consistent with better regulation, and in the interests of the circular economy, European Plasticisers calls on the
