Description
1
Product Introduction
Fireproof sleeves, also known as high-temperature-resistant sleeves, are made by weaving special alkali-free glass fiber yarn into a tubular structure. The tube is then coated with silicone rubber and treated at high temperatures.
The finished sleeve provides excellent high-temperature resistance, thermal insulation, flame retardancy, electrical insulation, aging resistance, and long-term durability. It is suitable for protecting cables, hoses, pipelines, and other equipment operating in harsh industrial environments.
