Material Notes:

Plaslok Corporation was purchased by Plastics Engineering Company (maker of Plenco brand materials) in March 2000. The Plaslok name is no longer in use.Plaslok 5440 is the replacement material for the former Union Carbide BMRS-5440. It is a two-stage, phenolic molding compound that has been successfully formulated to accommodate a very wide range of molding situations. Because of its balance of physical and electrical properties it has found use in a variety of applications including knobs, circuit breaker cases and wiring devices.Data provided by Plaslok Corporation.
