Description
D283 Prepreg. of Nomex paper / polyester film flexible laminates (NMN). NMN is a B-stage material in which NMN is coated with special heat-resistant resin, then followed by baking process. It has the characteristics of short curing time and long storage life under room temperature. After being cured, D283 has excellent electrical properties, good adhesive and heat resistance.
Application
D283 is used in Class-H dry-type transformers as layer insulation of low-voltage copper/ aluminum foil windings, also as well as slot insulation and interturn insulation in Class F and H electric motors or electric appliances.
