EM42 is a cream colored laminate available in a range of thicknesses from 0.8mm to 100mm and in sheet sizes 2400mm x 1220mm and 3000mm x 1220mm. Other sheet sizes are available on request.
EM42 exhibits both excellent reaction to fire and fire resistance. It is a flame retardant, low smoke and low toxic fume, material. It also has exceptional resistance to penetration when exposed to high power DC arcing.
EM42 can be drilled and machined easily and then converted to machined components and assemblies
Applications & Uses
- Applications
- Composites End Use
- General Applications
EM42 is suitable for use in electrical and mechanical applications specifically where there is a need for good reaction to fire, electrical performance or a high strength and impact resistant construction. EM42 is also an intrinsically fire resistant material and finds use in fire barrier/containment applications.

Safety & Health
- FIRE RESISTANCE
Fire resistance is a design/system property and not solely a material property. EM42 exhibits fire resistance both perpendicular to and parallel to, the laminate plane. At 12mm it has achieved in excess of 30 minutes integrity and 15 minutes insulation in an electrical bus-bar penetration of a fire partition and at 100mm it has achieved over 60 minutes integrity and 60 minutes insulation.
- DC POWER ARC RESISTANCE
DC power arc resistance is a design/system property and not solely a material property. EM42 exhibits high power arc resistance and has found application on several DC traction railway systems. It is a material selected by London Underground Ltd for arc resisting applications. A specific information sheet, available from MICAM, exists for this specialized area of use.
