Requirements for plastics in electrical engineering are
very stringent. The market is regulated by a multitude of
different standards, which means that very special,
flame-retardant-modified polymer materials must be available.
Composites are used in electrical applications where
high heat, mechanical stability and electrically isolative
conditions are needed. The strongest composite materials are
a combination of reinforcement, polymers and additives. They
can be designed to resist corrosion, chemicals, high
temperatures and fire; the mechanical properties can also be
Fibre composites combine high strength and low density
with excellent insulating properties. In addition, a high
resistance to chemicals, heat and fire can be obtained.
Composites are an evolving group of engineering materials
with large potential.
