Protect your electronic components from typical electromagnetic interference (EMI), electrostatic, or induced fields with these conductive polypropylene bins. The conductive material provides a barrier which these fields cannot penetrate and prevents the build-up of electrostatic charge. Bins are permanently conductive and are unaffected by washing with normal cleaners. Molded from a carbon filled copolymer polypropylene material with an electrostatic decay rate at less than 0.1 second that meets conductivity standards as tested with ASTM-D257 methods. Its surface resistivity is less than 10? Ohms-per square.
