Protect your electronic components from typical electromagnetic interference (EMI), electrostatic or induced fields with these molded, carbon-filled, copolymer polypropylene dividable grid containers. Surface resistivity is less than 105 Ohms-per square. The conductive material provides a barrier which these fields cannot penetrate and prevents the build-up of electrostatic charge. Containers, dividers and covers are permanently conductive and are unaffected by washing with normal cleaners. Containers have a load capacity of up to 100 lb.
