Product Description

Brief introduction of fiberglass acrylic casing:

Glass fiber acrylic sleeve, the product is made of glass fiber braided into a sleeve, then coated with acrylic resin and processed at high temperature. Polyurethane resin coating and high temperature treatment make it have good flexibility and elasticity, reliable mechanical properties, heat resistance, water resistance, good compressive strength, especially resistance to transformer oil.

Fiberglass Acrylic Sleeve


The synthesis of special high-temperature resistant materials for glass fiber acrylic casing determines that high-temperature casings have many other characteristics that are difficult to replace with other similar materials: high temperature resistance, thermal insulation, electrical insulation, chemical stability, weathering resistance, cold resistance, Water resistance, oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., especially safety and environmental protection performance, is a substitute for other hazardous products.


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

The alkali-free glass fiber in the glass fiber acrylic sleeve has strong tensile strength, will not be wrinkled or broken, is resistant to vulcanization, is smokeless, halogen-free, non-toxic, and has good insulation characteristics. After the organic silicone is cured, its safety and environmental protection performance is enhanced. 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 glass fiber acrylic 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. Splash-proof, multiple protection

In the smelting industry, the temperature of the medium in the electric furnace is extremely high, and it 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. Ultimately embrittlement and crack. Furthermore, unprotected equipment and cables are damaged. Multi-layer silicone coated glass fiber acrylic sleeves can achieve multiple safety protections. The temperature resistance can be as high as 200 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 pipelines, 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. In particular, 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

The glass fiber acrylic sleeve has strong chemical stability. The organic silicon does not react to oil, water, acid and alkali. It can be used for a long time without aging within 200 ℃, and the service life under natural environment can reach several decades. , Can greatly protect the pipelines, cables and equipment in these occasions, and greatly extend their service life.

6. Ozone resistance, voltage resistance, arc resistance and corona resistance

Because the outer surface of the glass fiber acrylic sleeve is coated with organic silica gel, its main chain is -Si-O-, which exists, so it is not easy to be decomposed by ultraviolet light and ozone. High temperature bushings have good electrical insulation properties. Their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. The impact is small. Therefore, they are a kind of stable electrical insulating materials, which are widely used in the electronics and electrical industries.

7. 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; the cable often burns due to local high temperature; the glass fiber acrylic sleeve is woven with extremely high temperature resistant glass fiber, and the surface is silica gel Special raw materials such as appropriate flame retardants are added 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.
