Diamond Dotted Film (DDF)
Diamond Dotted Film features a special dot pattern that creates air gaps for improved heat dissipation while maintaining electrical insulation. The pattern allows for better resin impregnation in winding applications.
Used in motor and transformer winding insulation where enhanced cooling and resin flow are beneficial.
