A research paper in Environmental Health Perspectives, a peer-reviewed journal published by the National Institute of Environmental Health Sciences, indicates from a study of most of the commonly used polymeric materials that nearly all showed estrogenic activity (EA) in as-fabricated form.
I don't have a link to the paper itself, but http://%3C/p%3E%3Cp%3Ehttp://www.plasticstoday.com/articles/study-says-bpa-free-plastics-still-show-estrogenic-activity-03042here's a link to a related news story.
EA is a substance characteristic that is known to be a promoter and perhaps also an initiator for estrogen-responding cancers, including breast cancer and others, affecting both men and women. EA also is implicated in various adverse developmental effects in utero, in progressively declining sperm counts and quality, and in various effects in other species including harmful mutations and decreased reproduction in fish, frogs and birds.
Prior studies have shown that many such polymers in pure resin form do not have EA. Apparently EA arises from thermal processing, material reactions, or post-fabrication stresses such as microwaving, UV exposure, etc.
BPA, a substance used in production of some polycarbonates and epoxies, is now widely recognized by consumers as having EA. Its use in body and food contact applications, especially for children and pregnant women, is quickly decreasing due to customer preference.
What will be the strategic impact on the medical device field if consumers and regulators follow the same course with other polymers that has been the case with BPA? Does your company have a no-plastics strategic plan?
