27 Glass Cloth Electrical Tape - OEM Data Sheet 1. Product Description 2. Applications 3M 27 Glass Cloth Electrical Tape is a woven glass cloth Insulating electric and induction type furnace power tape designed to operate in 600-volt dry applications supply leads requiring high mechanical strength and resistance to high temperatures. The adhesive is a pressure-sensitive rubber Securing systems requiring high mechanical strength and thermosetting system. The glass cloth is specially treated and resistance to high temperatures prepared to provide corrosion free protection The glass cloth will not shrink, rot, or burn and has a high tensile strength. Splicing wire that is rated 130C Contains pressure-sensitive thermosetting adhesive which Insulating motor lead connections, switches and controls for furnaces and ovens performs at Class B temperature (130F/266C) Reinforcing insulation in electrical installations where Provides heat stable insulation for hot spot applications heavy loads cause high heat and breakdown of original UL Recognized Component listing for 150C (Guide insulation (e.g., motor leads and switches) OANZ2, File E17385) CSA Accepted Component 130C, File LR93411 Excellent tensile and dielectric strength Properties Typical Values* Color White 1 Total Thickness 7.0 mil (0,177 mm) 1 Tensile Strength 150 lb./in (262 N/10mm) 1 Ultimate Elongation 5% 1 Adhesion to Steel 30 oz/in (3.3 N/10mm) Electrical Properties Typical Values* 1 Dielectric Strength 3000 volts 2 Electrolytic Corrosion Factor 0.9 *These are typical values and should not be used for specification purposes.
