As we reported in November and January, there is activity in blending polylactide (PLA) bioresins with engineering polymers for use in durable products such as laptops, cellphones, and auto parts. Now, polycarbonate/PLA blends are commercially available here from Bayer MaterialScience, Pittsburgh. New Makroblend BC250 and BC400 contain 25% and 40% PLA respectively. They are aimed at cellphones, portable electronics, furniture, sporting goods, toys, auto interiors, and housings/enclosures. Bayer says they do not readily decompose like straight PLA and retain good mechanical properties for users interested in durable materials derived from renewable resources. Meanwhile, Bayer also came out with two PC/ABS blends that contain post-consumer recycled (PCR) material. These are Bayer’s first PCR-content products. Of these, Bayblend FR610 GR is at least 10% PCR and at least 30% post-industrial recycle, for a total of at least 40% recycle content. It meets UL 94V-0 at 1.5 mm, 5VA at 3 mm. Bayblend FR630 GR is at least 30% PCR and total recycled content of at least 55%. It meets the same UL94 ratings as FR610 GR. Bayblend FR632 GR has the same PCR and recycled content as FR630 GR but meets UL 94V-0 at 1.2 mm. They are suitable for electrical lighting housings, business machines, and IT, telecom, and medical equipment. They reportedly can help OEMs gain one or two more points in the U.S. Government’s Electronic Product Environmental Assessment Tool (EPEAT) ratings. (800) 662-2927 • www.bayermaterialsciencenafta.com
