Product Details

3M TufQUIN 120

TufQUIN products are a hybrid inorganic/organic paper based upon advanced manufacturing techniques. TufQUIN offers the high-temperature capabilities of inorganic materials combined with the high mechanical strength gained by the use of organic fiber. TufQUIN papers can be combined with polyester film to form a flexible laminate uniquely suited for high temperature electrical insulation applications. Generically the same as TufQUIN 110, TufQUIN 120 employs a modified manufacturing process that yields thicker constructions while maintaining conformability.

Operating Temparature: 200°C

Thickness: 7.5Mil to 20Mil
