3M™ ThermaVolt Calendered Inorganic Insulating Paper Laminate is designed for insulating and protecting electrical equipment at high temperatures. It offers good thermal conductivity and coil bonding characteristics. 3M™ ThermaVolt Inorganic Insulating Paper Laminate is ideal for ground, layer and interwinding insulation. The conjunction of 3M ThermaVolt paper and polyester film make this laminate suitable for major high temperature applications. The calendering process exhibits optimized thermal conductivity and inorganic content offers long term voltage endurance. The tear resistant, polyester film reinforcement ensures enhanced mechanical strength to the paper.

It is suitable for Class 220(R) electrical insulation systems and 3M UL Recognized Insulation Systems may be found in UL File No. 65007. REACH Compliant and RoHS 2011/65/EU Compliant‎.
