High Temperature insulation Sleeving


Braiding, not only an art, but also our core technology.

Before the boom of the electronics industry, Good Gi had already begun to study braiding tubes.

Owning more than 1,500 braiding machines, we can offer all braiding tubes you need. Good Gi provides the most complete insulation solution with its coating experience for more than 30 years.

Since1988, we have applied many kinds of material such as varnish, silicone, polyurethane, polyvinyl chloride for coating and curing on tubes.

With its properties of high temperature resistance and insulation protection, our Fiberglass Sleeving is widely used in motors, transformers, household appliances, special lamps, electric heating equipment, and wire harness protection for electronic instruments and motor vehicles.

  1. Protect Your Wires in Extreme Heat: High Temperature Insulation Sleeving Explained

    High Temperature insulation Sleeving are protective coverings made of various materials such as fiberglass, silicone, or acrylic, which are designed to withstand high temperatures and provide thermal insulation for wires, cables, and other components. They are commonly used in industries such as aerospace, automotive, and electrical, where high temperatures and thermal insulation are critical for proper functioning and safety. High Temperature insulation Sleeving can help prevent heat damage, electrical shorts, and other issues caused by high temperatures.
