DyFlex® is a flexible insulator, formed by combining a non-woven fabric made of highly calendered short polyester fibres with a PET film. The non-woven material is laminated onto the film using appropriate adhesive substances, and the resulting laminate is then refined by soaking the non-woven material in synthetic resins. The result is a laminate with exceptional electrical insulation and mechanical properties.

‘DyFlex’ is available in saturated (SF and SDF models) and non-resin saturated (ISF and IDF models) variants. The non-resin-enriched variants are white in colour, while the resin-enriched ones are pink. DyFlex in other colours is available on request.

DyFlex laminates are used to insulate electric motors, transformers and electrical equipment in class F 155°C. In the case of electric motors or rotating machines in general, these laminates are used for slot and slot insulation gates as well as for phase separators on winding leads.


DyFlex® laminates are supplied on 910 mm wide rolls and with a core/insert diameter of 76 mm. DyFlex in different widths can be supplied on request - its minimum width is 10 mm.

GThe overall thickness tolerance is +/- 15% for film laminates in thicknesses up to 190μ and +/- 10% for 250 and 350μ film laminates. The weight and yield tolerance is +/- 12% (IEC 626).
