Nomex  Tape is an excellent insulator which offers good temperature resistance, dielectric strength, mechanical toughness, and flexibility. It is designed to opeElectrical Machine Phase / Slot Insulation Tapes

Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is an example of a meta variant of the aramids (Kevlar is a para aramid). Unlike Kevlar, Nomex strands cannot align during filament polymerization and have less strength: its ultimate tensile strength is 340 MPa (49,000 psi). However, it has excellent thermal, chemical, and radiation resistance for a polymer material. It can withstand temperatures of up to 370 °C (700 °F)..

Insulation tapes based on Nomex polyamide paper offer good temperature resistance, dielectric strength, mechanical toughness, flexibility, and flame retardancy. PPI self-adhesive tapes for electrical insulation encompass all insulation classes from Y to H in the working temperature range from -200°C to +400°C.

Heat-resistant thermoplastic adhesives possess good tack and adhesion but have limited resistance to solvents. Thermosetting adhesives cure when subjected to heat and in this way achieve excellent resistance to solvents, impregnating resins and cast resins. Heat-sealing adhesives, thermoplastic, as well as thermoset, can be initially activated by solvents or by heat and they all increase their level of adhesion with increases in pressure.

Applications:

Insulation for bar wound armature
Phase and Layer Insulation
Coil Banding and Wrapping
Polyimide based insulation tapes for very high temperatures

Applications:

Insulation for high-stress conditions in traction machine manufacturing, generator production
Outer wrap for transformers, toroidal coils, motor coils
Bundling of armature coils

Laminates for Transformers Shielding and Winding
Laminates for Transformers Shielding and Winding
yousan has developed an advanced range of film/foil laminates designed to assist with insulating coil windings.

Applications:

STATIC SHIELDS: Acting as an electromagnetic/electrostatic shield, the laminate is applied between the primary and secondary winding and also earthed.

DIRECT WINDING: Copper foil laminates are also used as replacements for copper wire in primary and secondary windings. Foil conductors have the advantage of a greater surface area for a given cross sectional area, when compared to wire conductors.

Capabilities:

Products available in a wide range of widths and thicknesses
Temperature Range – Heat Class B to Heat Class H
Bespoke design and specification upon customer request
Insulating Materials: Polyester, PEN Film, Polyimide, Nomex® & Others
Standard Foils: Copper, Tin-Clad Copper & Aluminium
Extended/cuffed/fringed/offset/single/double solder gap/multi-layer laminate options

FILM FOIL LAMINATE CONSTRUCTIONS AVAILABLE:

1. Laminates with two or more parallel strips of copper

2. Laminates with a wide range of film thicknesses and other insulating materials such as Nomex and Polyimide Film for classes F and H insulation

3. Metal foils with insulation laminated on one or both sides

4. Special shapes and die-cut pieces to customer design and specification

rate in the temperature range of 150°C to 220°C. It can operate at a continuous temperature of 220°C.
