DyFlex®

Non woven fleece and polyester laminates

Coveme DyFlex® insulating products derive from the coupling of a polyester non woven fleece with a polyester plastic film. The non woven polyester fleece employed is made out of short fibers strongly calendered to the polyester film by appropriate adhesives. The main function of the fabric is to improve the thermal aging perfor­mance of polyester film.
Coveme DyFlex® laminates are available as two plies fleece/pet laminate (ISF and SF) and three plies version fleece/pet/fleece (IDF and SDF).
Further improvements in the overall performance of the laminate are achieved by saturating the non woven fleece with special synthetic resins (SF and SDF).
The unsaturated versions are natural white, the saturated ones are pink (other colours available upon request).
Coveme DyFlex® laminates are designed for the insulation of electric motors, trans­formers and electrical equipment of class B 130˚C or F 155˚C. In electrical motors or, in general, in rotating machines, these laminates are used in slot closure and insulation as well as to separate phases on the heads of the windings. In transformers and elec­trical static equipment DyFlex® is used as interlay insulator.
