- 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.
