About this product

This sleeving is made of a special silicone rubber coated fibreglass braid. It gives both the benefits of an extruded silicone rubber as well as fibreglass sleeving, giving good strength and flexibility as well as excellent dielectric strength at high temperature. This sleeving peaks at 300°C.

  • Good dielectric strength
  • Halogen free
  • Self-extinguishing VW 1
  • Good mechanical resistance
  • Highly flexible
  • Flame retardant
  • Excellent chemical resistance to oils, fluids and aggressive chemical agents
  • Electrical insulation
  • Harnessing
  • Terminal protection
