Advantage:
DM polyester film Polyester Fiber non-woven fabric composite material has good stiffness, excellent dielectric properties, heat resistance, mechanical strength and impregnation
Application:
DM polyester film Polyester Fiber non-woven fabric composite material is suitable for slot insulation, gasket insulation and turn-to-turn insulation ofmotors and appliances.
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.
