Product Description
Dongfang is the leading manufacturer and exporter for electrical flexible lamiantes in China, even in Asia.
D279 is made from DMD and special heat resistant resin. It has the characteristics of long storage life,
low curing temperature and short curing time. After being cured, it has excellent electrical properties, good adhesion and heat resistance. The heat resistance is Class F. D279 is used as layer insulation or iner insulation of low-voltage copper/ aluminum foil winding in dry-type transformers as well as slot insulation and liner insulation in Class B and F electric motors and electric appliances. It passed the thermal ageing routine test fulfilled by Quality Supervision and Testing Center of China machinery industry for Electromechanical Materials. It also passed SGS test for toxic and hazardous substance detection.
