Alta-Glas HT

980 Series | Alta-Glas HT

Heat treated Fiberglas sleeving

  • Designed specifically for applications where temperatures as high as 500°C may be encountered
  • Maintains a round cross-section
  • Expands slightly providing some ease of installation
  • Flexibility allows for formation over tight radii in relatively close spacing
  • Available in standard wall thickness and can be made with a heavier wall for applications calling for ultimate protection
  • Often used over wires as durable, high temperature protection
  • Can be used as primary insulation over low voltage applications such as leads on some appliances and secondary insulation over primary extruded plastic and rubber insulated wire
  • Can be used as a high temperature gasketing material
