Description
Material: fiberglass yarn coated with silicone rubber
Shrink ratio: non-shrinkable
Features:
◆ Fire-proof and flame resistance
◆ Excellent heat insulation
◆ Flexible for easy operation
◆ High temperature resistance
◆ Excellent mechanical and dielectric performance
Application:
Silicone coated high-temperature resistant insulation fireproof sleeve is made of special alkali-free glass fiber carbon fiber yarn woven into a tube, and then coated with silicone resin for high-temperature treatment. It is mainly used for cable insulation protection in high-temperature places such as steel mills, smelters, and glass factories
Specifications:
| Items | Specification | Test Method |
