Xinmao insulation protective sleeve is made from high-quality E-glass fiber yarn woven into a tube, the silicone resin coated with organic heat through high temperature. Resistant protective sleeve has a fire-retardant insulation, insulation, thermal insulation, anti-electric, soft, and other properties. Insulation resistance, mainly used in cable insulation protective sleeve to protect steel mills, smelters, glass, fire-fighting equipment, large venues and other places of high temperature swing.

Xinmao insulation protective casing is widely used in high-temperature region in electric power, chemical, metallurgy, shipbuilding, machinery manufacturing and other industries; metallurgical enterprises heating zone cables, fluid lines, feed quick couplers, rolling area roller, mill cable, tubing; sawing surrounding cables, tubing and fittings; coated steel cable car so the field.

Product Features

Safety and environmental protection, protection of workers' health

E-glass fiber itself has an exceptionally strong rally, will not wrinkle break resistance, curing, smoking halogen-free non-toxic, non-flammable oxygen, good insulation properties, and then after the silicone cured, more to strengthen its safety and environmental performance, effective protection workers' health, reduce the incidence of occupational diseases. Unlike asbestos products such great harm to humans and the environment.

Superior high temperature performance

Xinmao insulation silicone protective sleeve surface structure contains both "organic group", also contain "inorganic structure", this particular composition and molecular structure of organic compounds and feature set make it inorganics-in-one. Compared with other polymer materials, the most prominent is the high temperature performance. Silicon - oxygen (Si-O) bond as the main chain structure, C-C bond energy of 82.6 kcal / mole, bond Si-O bond energy of 121 kcal / mol in the silicone, so Its high thermal stability at high temperatures (or radiation) molecular bond is not broken, do not break down. Silicone not only temperature but also low temperature, it can be used over a wide temperature range. Whether or chemical properties physical and mechanical properties, changes in temperature are very small.

Splash, multiple protection

In the smelting industry, medium temperature of the heating furnace are extremely easy to form a high temperature sputtering (welding industry for that matter), after cooling and solidification of slag formed in the pipe or cable, pipe or cable will make the outer rubber hardening, and finally brittle fracture. Further damage to unprotected devices and cables, through multi-channel silica-coated fire tube, to achieve multiple security, the highest temperature up to 1300 degrees Celsius, can effectively block the molten iron, molten copper, aluminum and other high-temperature melting melt splashing around the cable and prevent equipment from being damaged.

Insulation, energy saving, radiation-resistant

In the high-temperature workshop, a lot of pipes, valves or equipment, the internal temperature is very high, if not covering the protective material, likely causing burns or heat loss, etc. High temperature insulation fire protection sleeve, high temperature silicone fire tube, silicone sleeve has a better fire than other polymer materials, thermal stability and resistance to radiation and thermal insulation effect, prevent accidents, reduce energy consumption, can be prevented the heat medium in the pipe directly to ambient temperature leaving the shop, saving cooling costs small.

High-temperature fire casing species

1. Drum silicone tube fire tube, high temperature silicone fire tubes, glass fiber braided silicone tube fire

Generally suitable for the protection of shorter or less straight line, cable protection, automotive wiring harness, generators commonly used, after installing reliable, easy disassembly, sealing, insulation, heat, moisture is better.

2. The snap-on silicone fire tube, high temperature silicone fire tubes, glass fiber braided silicone tube fire

The advantage lies in easy accessibility, no disabled when installing the device, open the cable or the like, there is fire retardant internal suture of sticky tape, just to play a role in sealing the insulating sleeve from the intermediate bonding, not affecting equipment production and saves installation time. Commonly used in large-scale smelting equipment, high temperature metal hoses are also used.

3. fireproof silicone wound tube, high temperature silicone fire tubes, glass fiber braided silicone tube is mainly used for fire protection valve, pipe bending and other irregularities to be protected temperature protection, wrapped convenient, but also suitable for outdoor temperature pipeline, such as natural gas pipelines , heating pipes, etc., play the role of insulation, reducing heat loss.
