The fiberglass insulating sleeve adopt the American scientific and
  advance chemical formula, all of the chemical formula, all of the chemical
  materials are imported for improving the property, it’s mainly replace the
  PVC as silicon resin. The performance of burn-proof, voltage-resisting,
  elasticity and insulation. It has good insulation performance, high
  intensity, old-proof, heat- proof and high temperature-resisting. It’s security
  and easy to using, widely used for the heat-resisting & insulation
  material of electron and electrical cable of electrical appliance in the
  scope of aerospace, aviation, petroleum, metallurgy, coal, communication. We
  can produce it of different specification (dia.0.5mm~16mm)
  and voltage-resisting (1KV~7KV).
