3M™ Filament Reinforced Electrical Tape 1139 is a 6.5 mil thick, acrylic adhesive, solvent resistant, electrical tape. This tape is suitable for oil and air filled transfer applications and reinforcements, as well as for holding and separating ground insulation. The tape is 600V rated and withstands a temperature range of 32 to 311 °F (0 to 155 °C).

3M™ Tape 1139 with polyester film/glass filament backing has a pressure sensitive, acrylic adhesive that offers firm adherence. This high break strength tape is designed for applications that require both dielectric strength and mechanical strength. Ideal for bundling motor coils and coil covering. UL Listed and RoHS 2011/65/EU Compliant.
