Polyimid-Film

The polyimide film adhesive tape have following excellent properties: 1. Good high temperature - resistance anddielectric propertiesand used in wide temperature range without changing in tensile strength or insulating property. 2. Good chemical stability and resistance to corrosion. 3. Excellent flame retardant property,good radio-resistance. As H-class insulation material ,It is suitable for electrical magnetic wire and electrical motor.
