Stat-Rite M-200 alloy, an opaque, static-dissipative polypropylene-based alloy from BFGoodrich Performance Materials, is designed to provide clean, permanent electrostatic discharge (ESD) protection in semiconductor and medical device packaging and electronic component handling applications. It is part of BFGoodrich?s new line of inherently dissipative polymer alloys, which are two orders of magnitude lower in surface resistivity than existing ESD control technologies. These Stat-Rite polymer alloys produce rapid, consistent, and predictable static decay times as the result of a surface resistivity level that remains intact from the polymerization stage through compounding and molding.

The new M-200 alloy utilizes the patented Stat-Rite C-2300 static dissipative polymer. Unlike plastics that contain conductive fillers or chemical antistats, the M-200 alloy provides humidity-independent, permanent ESD protection without the risk of particulate, ionic, or dynamic off-gassing contaminants. It exhibits a flexural modulus of 200,000 psi, combined with good strength. Its surface and volume resistivity measure 2 by 1011 ohms/sq and 6 by 1011 ohms-cm, respectively. (Surface resistivity will be improved by two orders of magnitude when yet another formula is introduced in the first quarter of 1999.) BFGoodrich says M-200 is easily injection moldable into complex containers. Prices range from $2.50/lb to $3.00/lb for truckload quantities.
