Silicone Rubber Fiberglass Sleeve
Silicone rubber fiberglass sleeving (English name: Silicone rubber fiberglass sleeving), also known as fire-resistant sleeving, high-temperature resistant sleeving, is made of high-purity alkali-free glass fiber woven into a tube, and then coated with organic silica gel on the outer wall of the tube after vulcanization treatment. to make. After vulcanization, it can be used for a long time in the temperature range of -65°C-260°C and maintain its soft and elastic properties.
performance
The synthesis of special high-temperature-resistant materials determines that high-temperature casing has many other similar materials that are difficult to replace: high-temperature performance, thermal insulation performance, flame-retardant performance, electrical insulation performance, chemical stability, weathering resistance, cold resistance, and water resistance , Oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., especially safety and environmental protection performance, is the best substitute for asbestos and other hazardous products.
species
Tubular casing
It is generally suitable for protecting short or straight pipelines, cable protection, automobile wiring harness, and generator sets. It is reliable after installation, not easy to disassemble, sealed, insulated, heat-insulated, and moisture-proof.
Wound casing
It is mainly used for high temperature protection of irregular protected objects such as valves and curved pipes. It is convenient to wind. It is also suitable for outdoor high-temperature pipelines, such as natural gas pipelines and heating pipelines. It plays a role in heat preservation and heat insulation and reduces heat loss.
Buckle sleeve

Its advantage is that it is easy to disassemble and assemble. There is no need to stop the equipment and disassemble the cables during installation. The fire-resistant and flame-retardant hook-and-loop fasteners are stitched inside, and the casing can be sealed and insulated only by bonding the casing from the middle. Affect equipment production and save installation time. It is commonly used in large-scale smelting equipment, and also used in metal high-temperature hoses.


Features and applications
1. Safety and environmental protection, protect the health of workers
The alkali-free glass fiber itself has extremely strong tensile force, will not be wrinkled and broken, is vulcanized, is smoke-free, halogen-free, non-toxic, pure oxygen, non-combustible, and has good insulation characteristics. After the organic silica gel is cured, its safety and environmental protection performance is strengthened, and its protection is effective. Workers are healthy and reduce the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to the human body and the environment.
2. Superior high temperature resistance
The silicone structure on the surface of the silicone rubber glass fiber sleeve contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it integrate the characteristics of organic matter and the function of inorganic matter. Compared with other polymer materials, its most prominent feature is its high temperature resistance. With silicon-oxygen (Si-O) bond as the main chain structure, the bond energy of C-C bond is 82.6 kcal/mole, and the bond energy of Si-O bond is 121 kcal/mole in organosilicon, so Its thermal stability is high, and the chemical bonds of molecules will not break or decompose under high temperature (or radiation exposure). Silicone is not only resistant to high temperatures, but also resistant to low temperatures, and can be used in a wide temperature range. Whether it is chemical properties or physical mechanical properties, the change with temperature is very small.
3. Splash-proof, multiple protection
In the smelting industry, the temperature of the medium in the electric furnace is extremely high, which is easy to form high-temperature splash (the same is true in the electric welding industry). After cooling and solidification, slag is formed on the pipe or cable, which will harden the rubber on the outer layer of the pipe or cable, and finally Embrittlement and cracking. Furthermore, unprotected equipment and cables are damaged. Multi-layer silicone coated fiberglass sleeves can achieve multiple safety protections. The maximum temperature can be as high as 1300 degrees Celsius, which can effectively prevent high-temperature melting such as molten iron, molten copper, and molten aluminum. Splashing of objects to prevent damage to surrounding cables and equipment.
4. Thermal insulation, energy saving and consumption reduction, radiation resistance
In high-temperature workshops, many pipes, valves or equipment have very high internal temperatures. If they are not covered with protective materials, it is easy to cause burns or heat loss. Baite silicone rubber fiberglass casing has better thermal stability than other polymer materials, as well as radiation resistance and thermal insulation, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipeline from being directly transferred to The surrounding environment makes the temperature of the workshop too high, saving the cost of cooling.
5. Anti-moisture, anti-oil, anti-climatic aging, anti-pollution, and prolong the service life of equipment
Silicone rubber fiberglass sleeve has strong chemical stability. The organic silicon does not react to oil, water, acid, alkali and other substances. It can be used for a long time without aging within 260°C. The service life under natural environment can reach dozens of Years, can maximize the protection of pipelines, cables and equipment in these occasions, greatly extending their service life.
