Advantage:
NHN Polyimide film composite is one of the most exclusive electric insulation materials at present. It has excellent heat-resistant, dielectric property, and superior mechanical properties.
Application:
NHN Polyimide film composite can be used for slot insulation of H class motors and electrical appliances, inter-turn insulation, gasket insulation, and interlayer insulation of dry-type transformers.
Notice:
1. During slitting and use, edge gaps and cracks should be prevented to avoid tearing during operation and to avoid surface scratches, oil and dust pollution.
2. Store in an environment below 40℃, keep clean and dry, away from heat sources, and avoid direct sunlight.
3. The storage period is one year. If it exceeds the storage period, it can still be used if it passes the test according to the technical requirements.
