Products Description

Composition:
DM 6630 is three-layer flexible insulation material consisting of PET film and non-woven polyester fabric.

Application:
DM 6630 is used as slot insulation and phase insulation for low voltage motor, as well as the interlayer insulation for transformers.

Performance:
DM 6630 insulation paper has excellent electrical and mechanical performance. The non-woven polyester fabric is porous and absorbs resin when impregnated.The smooth surface of the DM6644 insulation paper enables easy processing on automatic machines.

Storage:
Under normal conditions (20℃,50% relative humidity), can be stored indefinitely

Supply condition:
Cut in sheet, max. size: 1000*980mm
In Roll: 5~1000mm width
