Fiberglass Insulation

Glass fiber insulation is a kind of inorganic nonmetallic material with excellent performance. It has been widely used in many fields because of its excellent insulation, heat resistance, corrosion resistance and high strength. The following is a detailed introduction to glass fiber insulation products.

 

 

Glass fiber insulation materials are mainly made of glass balls or waste glass as raw materials, through high temperature melting, wire drawing, yarn winding, weaving and other processes. The diameter of its monofilament is usually between a few microns to more than twenty microns, equivalent to 1/20-1/5 of a human hair, and each bundle of fiber fibril consists of hundreds or even thousands of monofilaments.

 

 

 

1.Excellent insulation:

• Glass fiber is a good electrical insulator, by adjusting the proportion of its components, can effectively improve the dielectric properties, so that it has relatively high dielectric strength and low dielectric constant.
• Glass fiber insulation material is widely used in the field of circuit board, wire and cable, which can effectively prevent current leakage and short circuit.

 

2.Good heat resistance:

• Glass fiber has a low coefficient of thermal expansion and a high coefficient of thermal conductivity, thermal stability is not easily affected by the external ambient temperature, and still maintains good performance in the thermal environment.
• It is suitable for insulation and insulation materials in high temperature environment, such as industrial furnace, high temperature pipeline, etc.

 

3.Excellent corrosion resistance:

• Glass fiber has good resistance to most of the chemical corrosion of the outside world and the pollution of pests and bacteria.
• It is suitable for filtration materials and anti-corrosion materials in chemical industry.

 

4.High strength:

• Glass fiber has high tensile strength and elastic modulus, and can withstand large external forces.
• It is often used for reinforcing materials in composite materials, such as glass fiber reinforced plastic and so on.

 

5.No moisture absorption:

• Glass fiber will not decompose or occur other physical and chemical reactions due to water in a humid environment, and can maintain high mechanical properties in a humid environment.
• Suitable for insulation and insulation materials in humid environments, such as basements, bathrooms, etc.

 

 

 

There are many kinds of glass fiber insulation materials, which can be divided into continuous fiber, fixed length fiber and glass wool according to shape and length; According to the glass composition can be divided into alkali free, chemical resistance, high alkali, medium alkali, high strength, high elastic modulus and alkali resistant glass fiber.

 

1.Grade E glass fiber:

• Also known as alkali-free glass fiber, it has good electrical insulation and mechanical properties, and is widely used in the production of electrical insulation glass fiber and glass fiber for glass steel.
• However, it is easily eroded by inorganic acid and is not suitable for use in acidic environment.

 

2.Grade C glass fiber:

• Also known as medium alkali glass fiber, chemical resistance, especially acid resistance, is better than alkali-free glass, but the electrical performance is poor, and the mechanical strength is lower than that of alkali-free glass fiber.
• Commonly used in the production of corrosion resistant glass fiber products, such as glass fiber surface felt.

 

3.High strength glass fiber:

• With high strength and high modulus, the tensile strength of single fiber is about 25% higher than that of non-alkali glass fiber, and the elastic modulus is high.
• Used in military, space, bulletproof armor and sports equipment and other fields.

 

4.AR glass fiber:

Alkali resistant glass fiber, mainly used to strengthen cement.

 

 

 

Glass fiber insulation materials have been widely used in many fields because of their excellent properties:

 

1.Construction field:

• It is used for building external wall insulation system to improve the energy efficiency of buildings and reduce energy consumption.
• Used to strengthen concrete, improve compressive strength and crack resistance.

 

2.Transportation field:

• In the automotive industry, it is used to manufacture body structure parts and interior trim parts to reduce vehicle weight and improve fuel efficiency.
• In the field of aircraft manufacturing, because of its high performance and reliability, it has become one of the key materials.

 

3.Electronic and electrical fields:

• Used for the production of printed circuit board (PCB), with good insulation and mechanical properties.
• It is used to manufacture high-performance wire and cable with fast transmission speed and small signal loss.

 

4.Environmental protection and Sustainable Development:

• Glass fiber has good recyclability and reusability, reducing resource consumption and environmental pollution.
• Used in the field of water treatment, the filter material is made to remove impurities and pollutants in water.

 

 

 

China is currently the largest producer of glass fiber and the largest market for global glass fiber industry demand and application. With the continuous improvement of glass fiber penetration in emerging fields such as transportation, electronics, and wind power, the upgrading of its industry demand structure will further expand the development space. In the future, the development trend of the glass fiber industry will be high-end and intelligent, and enterprises with industry-leading technology, superior product structure, excellent quality and service will be more competitive.
