The new Acrovyn® 4000 wall and door protection line contains no PBTs (persistent bioacummulative toxins), is completely free of PVC and BPA (bisphenol A), and offers the same high-impact strength and UL Class 1 fire rating as original Acrovyn. Acrovyn 4000 has earned MBDC Cradle to Cradle: Silver Certification and meets California 01350 protocol for good indoor air quality. To enhance aesthetics, improve cleanability, and hide abrasions, Acrovyn 4000 also features a new contemporary texture. http://www.c-sgroup.com/
