Conductive Polyurethane Foam
EC1002
Low density urethane, stiffened and unstiffened, is available for packaging of odd shaped parts for the transportation of printed circuits, computer chips, etc. Conductive Plastics also has high density and ultra high density conductive foam. The high density foams are specifically engineered for lead insertion and are designed to prevent degradation.
An outstanding advantage for using Conductive Plastics conductive foam is cleanliness. There is no sloughing. It's non-corrosive and does not particulate. Conductive foam is available in standard sheets, hot wired, die cut, convoluted and laminated to other substrates, such as pressure sensitive adhesive.
