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 a electrostatic decay rate at less than 0.1 second that meets military specification Mil-B-81075B. Its surface resistivity is less than 10⁵ Ohms-per square. Be sure all units are properly grounded according to your use. Color is Black.
