Esspee supply an extensive range of silicone & epoxy resin glass laminates. The family of materials offers high mechanical strength, low moisture absorption and excellent electrical properties.

Available in sheet rod and tube form, they have good dimensional stability and high wear resistance. Both Silicone and Epoxy glass products can be used in a wide range of applications where stability, strength, and electrical properties are all needed.

Silicone and epoxy based machined parts lend themselves particularly well as electrical insulation in turbine generators, cryogenic superconducting magnets and bolt isolation for structures.

Other benefits include:

  • Machinable
  • Good thermal conductivity
  • High flexural and compressive strength
  • Available in sheet, rod and tube
  • Good electrical resistance
  • Load bearing
