Top quality materials for mechanical and electrical applications.
The TUFNOL range of high quality epoxy resin bonded glass fabric laminates offer 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 and good resistance to a wide range of working environments. Four standard grades are available:
• TUFNOL Grade 10G/40 - The most widely used grade, suitable for continuous use at temperatures up to approximately 130°C. (Class B).
• TUFNOL Grade 10G/41 - Similar to 10G/40, but with comtrolled f lammability
• TUFNOL Grade 10G/42 - Made with an epoxy resin which offers increased mechanical strength at higher temperatures. Suitable for uses up to 155 °C (Class F).
• TUFNOL Grade 10G/44 - Similar to Grade 10G/42, but with improved retention of strength after heat ageing.
What are TUFNOL epoxy glass fabric materials 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 performance 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 fibre content, epoxy glass grades are not normally selected for wearing or bearing applications.
