Epoxy glass

Epoxy glass belongs to the group of laminar products obtained through several glass fabrics compaction in an increased temperature impregnated with an epoxy resin. They are used as structural components in electrical equipment. They are suitable for work in air and oil in high voltage installations. They have very good dielectric properties and mechanical properties and are characterized by low water absorption. There are available in the form of plates with dimensions of 1000 x 1000 mm (optional 1000 x 2000m), as well as in bars, rods and sleeves.
