Material Notes:

EMD is a glass mat reinforced polyester sheet designed primarily as a "slot wedge" material in large motors and generators. EMD has low weight loss at elevated temperatures and high flexural and shear strength; properties required in demanding "slot wedge" applications. Available thicknesses - .062" - 1.00". Standard color - Black.Information provided by Haysite
