Perstorp developed Pevalen (PETV or pentaerythritol tetravalerate) to provide uncompromising performance in close-to-consumer applications in flexible PVC.
It is already widely used for products such as coated fabrics, but approval for use in products made from flexible PVC that may come into contact with food — conveyor belts in food preparation for example — is ongoing owing to more strict testing requirements.
The recently completed test, done by the independent Research Toxicology Centre (RTC) in Pomezia, Italy, is a key requirement for approval by the US Food and Drug Administration.
The tests showed that Pevalen is non-toxic, even at the highest dosage that is required by standard protocols.
“This study is the latest and most detailed of several studies showing that Pevalen is non-toxic,” says Carina Fogelberg, Product Stewardship & Regulatory Affairs Specialist at Perstorp. “We are obviously very happy with the results, and we shall now move ahead to obtain full food contact approvals as soon as possible.”
At PVC Formulation 2017 in Düsseldorf, Germany, (Feb 28-Mar 1), Perstorp’s Technical Market Development Manager for Plasticizers, Anders Magnusson, will discuss the use of PETV, on the final day at 13.50.
Anders will also give a presentation on April 27 at 12.00 at the PVC 2017 conference in Brighton, UK (April 25-27). Several Perstorp colleagues will be on hand for discussions at both events.
