Product Description

Introduction to Silicone Fiberglass Sleeve:

Silicone glass fiber sleeve is made of high-purity alkali-free glass fiber woven into a tube, and then the outer wall of the tube is coated with organic silica gel and then vulcanized.

Silicon resin Fiberglass Sleeve


1. Safety and environmental protection, protect the health of workers

The alkali-free glass fiber in the silicone fiberglass sleeve has strong tensile strength, will not be wrinkled or broken, is resistant to vulcanization, is smoke-free, halogen-free, non-toxic, pure oxygen, non-combustible, and has good insulation characteristics. It will be strengthened after being cured by organic silica gel. Its safety and environmental performance can effectively protect the health of workers and reduce the incidence of occupational diseases. Unlike other 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 fiberglass 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 outstanding performance is high temperature resistance. With silicon-oxygen (Si-O) as the main chain structure, the energy of C-C is 82.6 kcal/mole, and the energy of Si-O in organic silicon is 121 kcal/mole, so its thermal stability is high , Under high temperature (or radiation exposure), the chemistry of molecules will not break or decompose. Silicone is not only resistant to high temperature, but also resistant to low temperature, 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. Flame retardant, reduce the incidence and spread of fire

If the pipeline conveys flammable or toxic media, it is easy to cause fire or casualties when leakage occurs; cables often burn due to local high temperatures; silicone fiberglass sleeves are woven with extremely high temperature resistant glass fibers, and the surface The silica gel is added with appropriate flame retardants and other special materials to make it have excellent flame retardancy. Even if a fire occurs, it can prevent the fire from spreading, and can still protect the internal pipelines from damage for a long time, providing sufficient time for the rescue of important information such as data and materials.

Application range of silicone fiberglass sleeving:

Wire harnesses, hot runners, heating area cables, fluid pipelines, rolling mill cables, oil pipes, sawing edge cables, generator sets, electrical voltage equipment, oxygen sensors, large buildings, hydraulic systems, automotive wiring harnesses, H&N class motors, household appliances , Insulation protection for electric heating equipment, special lamps, electronic instruments, etc.
