New Polycarbonate Blend Available

A new line of polycarbonate and ABS blends may be capable of replacing PC resins in certain applications at a lower cost. Bayer Corp. (Pittsburgh), plans to have the line of blends available before the end of this year and calls them a "new generation of flame-retardant blends that meet many of the needs for thin-wall molded parts for the medical market." According to Bayer, the Bayblend FR 3000 blends were developed in response to the shortage of PC resins and the abundance of ABS.

The new grades, FR 3000, FR 3010, and FR 3020, are free of antimony, bromine, and chlorine, and meet the requirements of the UL 94 standard for flammability. Bayer says the new blends are easy to process and have improved hydrolytic stability and reduced volatiles during processing. According to a Bayer spokesman, Kit Newton, the new resins' primary use in the device sector would be for molding medical equipment housings.
