ESD foams effectively protect electronic components from mechanical damage and electrostatic discharge. Flexible, lightweight polyethylene (PE) and polyurethane (PU) foams offer good shock absorption and cushioning. They are also resistant to chemicals and moisture. The materials are ideal for use as plug-in foam, interlayers, partitions in containers and as workplace underlays in ESD-protected areas. They therefore make a significant contribution to the safety and integrity of sensitive components.
