VOLTAFLEX® 6644 flexible insulating laminates are made by hot-melting a polyester film and a layer of polyester non-woven fabric impregnated with high-temperature resin. The polyester non-woven layer increases the polyester's resistance to thermal aging. The polyester film, by varying its thickness, allows for a wide range of laminates to be obtained.
Maximum operating temperature: Class B/F – 130/155°C (IEC 60216) Class F – 155°C (UL 1446)
Minimum operating temperature: Resin -60° / Polyester -60°C
Characteristics: insulating paper suitable for the insulation of transformers, in slots in motors and in all those electrical equipment that require:
excellent electrical insulation – excellent mechanical resistance – good thermal resistance.
