Electrical Insulation
electrical-insulation
DMD 70 is uncoated.
DMD100 is coated and operates to 155C.
DMD180 is UL system recognized as rated to 180C.
Kraft Laminates have good temperature capabilities with improved dielectric strength, and very good mechanical properties as a result of the polyester film laminates. The laminate provides excellent cut-through resistance, good stiffness with improved resistance to tearing.
3M™ CeQUIN I and II Inorganic Insulating Papers have high inorganic content and are comprised of glass fibers, microfibers, and inorganic fillers with less than 10% organic binder content. It performs to temperature up to 250 ºC while UL systems recognized to Class 220(R) and CSA Component approved. CeQUIN possess excellent thermal conductivity, good varnish absorption, good retained dielectric and low moisture absorption.
CeQUIN I Thicknesses: ranges from 5 mils to 30 mils
CeQUIN II Thicknesses: range from 30 mil to 60 mil
CeQUINlaminates available in standard constructions
3M TufQUIN™ 120 Hybrid Insulating Paper is generically the same as TufQUIN™ 110 paper, with the exception that TufQUIN™ 120 paper is created through a modified manufacturing process that yields thicker constructions while maintaining conformability.
