Laminated Products

---

🔹 DM is derive from the coupling of a polyester non woven fleece with a polyester film. The non woven polyester fleece employed is made out of short fibers strongly calendered to the polyester film by appropriate adhesives.

DM is 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.

🔹 NM is produced by the a layer of aramid paper with polyester film. Aramid layer stick firmly to the plastic film by appropriate adhesives. Laminates area highly performing solution for the insulation of electric motors, transformers and electrical machines with working temperatures up to class F 155°C and H 180°C.

🔹 NK insulating product is produced by the coupling of aramid paper with polyimide. Aramid layer stick firmly to the polyimide by appropriate adhesives. NK is a highly performing solution for the insulation of electric machines with working temperatures up to 200°C. The presence of films enhances the mechanical, physical and dielectrical properties of the laminate. In rotating machines, NK is used in slot closure and insulation, as well as to separate phases on the heads of the windings. In transformers and electrical static equipments, NK is used as interlayer insulating material.

🔹 DMD is three plies version polyester fleece/pet/fleece. Further improvements in the overall performance of the laminate are achieved by saturating the non woven polyester fleece.

The saturated and unsaturated versions are available with natural white and pink colour.

Prepreg products are flexible insulating materials with a B-Stage (semi polymerized) resin. During coating process the resin is first applied onto the substrate then, by controlled heating, the polymerization is started bringing the resin to the so called B-Stage, where free to the touch, reasonably stable but not fully polymerized. The final product depends on the substrate used for the resin coating.

Available type of the prepregs; PET Prepreg, DMD Prepreg, NMN Prepreg.
The resin can be of natural or red brick colours, applied in various grammages, on one or both sides, and on the full surface.
B-Stage prepregs can be used by the manufacturer as any conventional insulating material. After the manufacturing operations the final equipment is exposed to heat. The resin will initially melt, creating a uniform distribution and filling any possible non uniformity, before polymerizing to its final solid stage cementing the prepreg products to the conductors to be insulated. Prepregs are used as electrical insulator in mainly in electrical transformers (dry, oil filled, or SF6 gas), generators and electrical motors. Depending on the substrate used Prepregs are suitable for working temperatures up to class H 180°C.

Multi Layer PET Products are made laminating several PET film layers, several PET film layers with both side non woven fleece and several PET film layers with both side aramid paper with a solvent glue at controlled reticulation, according to ASTM D1830 standard. 

The product is especially used for physical separation between primary and secondary winding of cast resin transformers in thermal class F 155°C or H 180°C. 

Available variants  thicknesses 0,5mm to 1,5mm.
