16 I 2015 - Doubts about co-polyesters replacing PC

On December 4, 2014 the peer-reviewed scientific journal Environmental Health published a new study assessing the release of chemicals with estrogenic activity (EA) from thermoplastic resins: http://www.ehjournal.net/content/13/1/103/abstract

 

The scientists report that four tested resins leached chemicals with EA, including one polystyrene (PS), and three Tritan™ resins, the latter labeled as EA-free. Therefore, the current study shows that it is possible to manufacture PC-replacement plastic products from EA-free resins, given that EA-free additives are chosen.

The first author of the study, George Bittner, has been previously involved in a law suit with Eastman Chemical concerning claims made about Tritan™ manufactured by the company (http://www.plasticstoday.com/articles/Eastman-Chemical-files-lawsuit-over-Tritan-estrogenic-activity-claims-0615201201).
