Product Description


Electrical Insulation Paper DMD Prepreg
Type:Insulation composite material, Insulation Materials
Application:High Voltage
Thickness:0.15/0.18/0.20/0.25/0.30(mm)
Width: 980(mm)(Customized Size)

Details:
Prepreg DMD is formed in the process of precuring the modified class F DMD with impregnation of high temperature resistant B-stage epoxy resin by baking. It is class F (155ºC) insulation and has good dielectric property and heat resistance.
It is widely used for turn insulation in dry type transformers and slot insulation, phase insulation in class F electric motors.
Normal Thickness: 0.18-0.40mm
Normal width: 1000mm 
Normal color: red, white


Properties
Prepreg DMD is formed in the process of precuring the modified F-class DMD with Impregnation of hi-temp resistant B-stage Epoxy resin by baking. With long shelf life at room temp, low precuring temp & time, excellent electrical insulation, bonding and heat-resistant properties. Its thermal Glass is F, widely used for liner insulation of copper foil (aluminum foil)-wrapped Low voltage coils in dry-type transformer and slot insulation & phase insulation in B~F class Motor & electrical appliances.
