Polyester Film/ Polyester Non-woven Fabric Combined Flexible Material
Product Description:
1. COMPOSITION AND PRESENTATION
FW-6630A is polyester film/polyester fiber non-woven fabric flexible laminate (DMD). It is a three-layer flexible laminate in which polyester fiber non-woven fabric (D) is bonded to the two side of polyester film (M).
2. PROPERTIES AND APPLICATIONS.
FW-6630A (DMD) shows excellent electric insulating properties, heat resistance, and mechanical strength and impregnated properties. It is suitable for slot insulation, interphase insulation and liner insulation in Y-series electrical motors and electric apparatus. Heat resistance is Class B. 6630A is more flexible than 6630, it is suitable for the process of hand-work inserting slot.
