Fiberglass Sleeve

What is fiberglass Sleeve?

 
As the name implies, fiberglass sleeve is a kind of tubular insulating material made of alkali-free glass fibers woven or wound, coated with special resins and then heated and cured. It combines the high strength of glass fibers with the insulation of resins to form a product with excellent electrical insulation, high temperature resistance, flame retardancy, and strong chemical stability.
Classification of fiberglass sleeves
 
Fiberglass sleeve, as a high-quality insulating protective material, has been widely used in many industries due to its excellent electrical insulation, high temperature resistance and chemical stability. Fiberglass sleeves are available in a variety of materials and types to meet the needs of different application scenarios.
According to the coated material, fiberglass sleeves are mainly divided into the following categories.fiberglass sleeves of different materials and structures have their own characteristics and are suitable for different application scenarios. As a senior fiberglass sleeve product expert, we are always committed to providing customers with the most suitable insulation protection solutions to meet various needs and ensure the safe operation of equipment.
Silicone rubber coated fiberglass sleeve
This type of fiberglass sleeve is made of alkali-free glass fiber woven into a tube, coated with silicone rubber on the outer layer of the tube, and then cured. It has good high temperature resistance and can be used for a long time in the temperature range of -60℃ to 200℃. Silicone rubber fiberglass sleeve is soft, wear-resistant and aging-resistant, suitable for insulation protection of various wire harnesses and cables.
PVC fiberglass Sleeve
PVC fiberglass Sleeve is made of polyvinyl chloride (PVC) and glass fiber, with excellent chemical resistance, corrosion resistance and electrical insulation. The temperature resistance of PVC fiberglass sleeve is usually between 70℃ and 80℃, which is suitable for insulation protection in general industrial environments.

Applications

Acrylic fiberglass Sleeve
Acrylic fiberglass sleeve is an insulating material composited with acrylic resin and glass fiber. This type of fiberglass sleeve has reliable heat resistance, good softness and elasticity, and electrical insulation performance. The temperature resistance of acrylic fiberglass sleeve is usually around 100℃, which is suitable for insulation protection of electronic and electrical products.
Polyurethane fiberglass Sleeve
Polyurethane fiberglass Sleeve has high mechanical strength and wear resistance, and is suitable for insulation environments with higher requirements. Its temperature resistance is slightly lower than that of silicone coated fiberglass sleeve, but it has advantages in certain specific areas.
 
cold shrink tube Telecommunications
New Energy Vehicles Industry
In the rapid development and innovation of new energy vehicles, the insulation protection of motor harnesses has become a crucial link. Volsun fiberglass sleeve, with its unique softness, excellent high temperature resistance and excellent flame retardant properties, has become the preferred material for insulation protection of motor harnesses of new energy vehicles.
The excellent flexibility enables it to easily adapt to the bending and twisting of various complex harnesses, ensuring that the harness is not affected by external factors during the operation of the vehicle and maintains a stable insulation state. In addition, even in a temperature environment of up to 200°C, the fiberglass sleeve can still maintain structural integrity and insulation performance without degradation, effectively protecting the harness from high temperature damage.
cold shrink tube Electric Power
Rail Transit Industry
In the field of special vehicles and rail transit, circuit insulation protection is crucial, which is not only related to the stable operation of the equipment, but also the key to ensuring the safety of passengers. Volsun fiberglass sleeve, with its extraordinary high dielectric strength, excellent flexibility, excellent heat aging resistance, high-efficiency flame retardancy, and temperature resistance up to 200°C, has become an ideal choice for circuit insulation protection in these fields.
The high dielectric strength of volsun fiberglass sleeve ensures that the circuit can withstand the impact of high voltage under complex and changeable working conditions, effectively prevent insulation breakdown, and ensure the safety and reliability of the circuit system. Its good flexibility enables the fiberglass tube to flexibly adapt to various bending and compression environments, perfectly fit the complex wiring harness layout of special vehicles and rail transit, and does not affect the normal operation of the equipment.
cold shrink Photovoltaic Industry
Insulation Protection of Circuit Harness
In terms of precision wire harness protection in the field of electronics and electrical, Volsun fiberglass sleeves have set new industry standards with their unique combination of properties. This product combines high dielectric strength, excellent flexibility, long-lasting heat aging resistance, efficient flame retardancy, and the ability to withstand high temperatures of 200°C, providing solid insulation protection for wire harnesses in a variety of electronic and electrical industries.
Excellent high temperature resistance enables it to maintain its performance unchanged in high temperature environments, effectively resist thermal decay, extend the service life of the wire harness, and reduce maintenance and replacement costs caused by temperature changes.
Volsun fiberglass sleeves have proven their value in a wide range of applications in the electronics and electrical industry. Whether it is home appliances, industrial control equipment or new energy vehicles, our fiberglass sleeves can be found.

How to produce fiberglass sleeves?

Do you know how to produce fiberglass sleeves? The main processes are braiding, coating, winding, cutting etc. Through the following specific process details, you will know the produce process of fiberglass sleeves.

Firstly, Raw material preparation
Select high-quality alkali-free glass fiber and high-quality silicone rubber that meet national standards to ensure stable product performance.

Secondly, Braided embryonal tube

Pre-treat the alkali-free glass fiber to improve the flexibility of the fiber, and use a high-speed braiding machine to weave the alkali-free glass fiber into an embryonal tube to ensure that the embryonal tube structure is tight and uniform.

Thirdly, Surface treatment of embryonal tube

After the embryonal tube is woven, the surface burr is treated to remove excess fiber heads to ensure that the surface of the embryonal tube is smooth.

Next, Passing the embryonal tube

Pass the treated embryonal tube through a special embryonal tube passing equipment to ensure that the embryonal tube is unobstructed. If there is any abnormality, adjust it in time.

Then, Coating

Use a special coating equipment to evenly apply silicone rubber on the surface of the embryo tube.
Control the coating thickness to ensure that the silicone rubber fully covers the glass fiber and improve the insulation performance of the product.

The last step, Winding and packaging

Finally, the glass fiber sleeve is wound, and it can also be cut according to customer needs.
Strict quality inspection is carried out at every stage of the production process to ensure that the product is qualified.
Sampling inspection is carried out before leaving the factory to ensure that product performance meets national standards.
Through the above production process, the glass fiber sleeve that we produced has excellent heat resistance, cold resistance, and insulation performance, and is widely used in various electrical equipment, aerospace, automobile and other fields.
