Szkłoflex, also known as Izoflex, is an electrical insulation material made from fiberglass impregnated with special insulating resins. This material is used in the electrical industry as insulation for windings and conductive elements in electrical devices.

Due to its structure, szkłoflex exhibits very good mechanical resistance and high thermal stability. The material belongs to the temperature class F (155°C), allowing its use in devices operating at elevated temperatures.

Fiberglass materials are particularly valued in applications requiring durable electrical insulation and high resistance to temperature, moisture, and chemical factors. Therefore, szkłoflex is widely used in the electrical, energy, and electric machine manufacturing industries.

Szkłoflex is available in various thicknesses and widths, most commonly in the form of rolls, allowing the material to be tailored to specific technological applications.

FAQ – frequently asked questions

What is szkłoflex?

Szkłoflex is an electrical insulation material made from fiberglass impregnated with insulating resin. It is used in electrical devices as insulation for windings and conductive elements.

What is szkłoflex used for?

Szkłoflex is primarily used in electric motors, transformers, and generators. The material is used as slot insulation, insulating spacers, and protective elements for windings.

What working temperature can szkłoflex withstand?

Szkłoflex belongs to the temperature class F (155°C), allowing it to be used in devices operating at elevated temperatures.

In what form is szkłoflex available?

Szkłoflex is most commonly available in the form of rolls of various widths and thicknesses. Depending on the needs, the material can also be cut to specific dimensions.

How does szkłoflex differ from prespan?

Prespan is a material made from pressed cellulose fibers and is mainly used in transformers as rigid structural insulation. Szkłoflex, on the other hand, is made from fiberglass and has significantly greater temperature resistance and better mechanical strength.
