This plastic is primarily used as an insulation material in panel construction and in the production of generators and large switches. Thanks to the combination of polyester resin and glass fibre filling the material is mechanically strong, has excellent electrical insulation property and is temperature resistant. The GPO-3 type is halogen-free, absorbs little moisture and is self-extinguishing. Extra advantages are the low electrical losses at high frequencies and the high tracking and arc resistance. With the right tools the material can be well machined and can be used to +155°C. Standard colours are red and white, other variants are available on request.
