Tufnol Grade 10G/41

Tufnol Grade 10G/41 is a high quality epoxy resin bonded glass fabric laminate. It offers very high mechanical strength and low moisture absorption, combined with excellent electrical properties, under both dry and humid conditions. They are rigid materials with good dimensional stability, controlled flammability and good resistance to a wide range of working environments.

What is Grade 10G/41 used for?
  • These high-performance materials are used for a very wIde variety of applications where high strength, rigidity dimensional stability and electrical performance are required.
  • Applications such as insulation in large turbine generators, components for cryogenic superconducting magnets, high-strength bolt insulation in structures, jigs for electro-chemical machining and structural insulation for high peformance electronic equipment, these are typical of the many uses to which this material is put.
  • However, due to the abrasive nature of the high glass fiber content, epoxy glass grades are not normally selected for wearing or bearing applications.
