Tufnol® 10G40

Tufnol® 10G40

Tufnol® 10G40 is an epoxy glass laminate. It is primarily used where high strength, rigidity, dimensional stability and electrical performance are key requirements. We offer G10 as an alternative to Tufnol® 10G40.


Common applications include insulation in large turbine generators, components for cryogenic super-conducting magnets, high strength bolt insulation in structures, jigs for electro-chemical machining and structural insulation for high performance electronic equipment. It is not ideal for use in wearing or bearing applications.
