Hard insulation materials

Glass fibre reinforced polyester panels. High chemical and temperature resistance are their characteristic features, have very good mechanical properties and high thermal and electrical insulation parameters.

Epoxy glass cloth panel – a laminate consisting of glass fabric saturated with epoxy resin may also be referred to as glass textolite or glass resotextile.

Electrical insulation moulders

We manufacture electro-insulating plastic components according to customer-supplied documentation.

Bakelite - phenolic paper panels and tubes

Bakelit jBakelite is a paper-phenolic laminate. It is manufactured from special electro-insulating paper saturated with phenolic resins. Bakelite is characterised by the stability of its mechanical properties over a wide temperature range. It can operate at temperatures up to 120°C.

Glass-epoxy profiles (tubes, dogbone profiles, etc.)

Glass-reinforced plastic profiles in the electrical industry are used primarily in the construction of transformers and electric motors. The range of products is substantial. We have virtually all existing sizes of insulation material on the market. Proprietary moulds...

Beech profiles and moulders

Components made of this wood are dent-resistant and can be subjected to heavy loads.
