    In modern industry and high-tech fields, the choice of insulation materials is crucial. Whether it is power transmission, electronic equipment or building structures, high-quality insulation materials can ensure the safety and stability of the system. As a high-performance insulation material, glass fiber spun yarn has shown excellent performance in many application scenarios due to its excellent physical and chemical properties. This article will explore the characteristics of glass fiber spun yarn, its importance in insulation materials, specific application cases, and explain in detail why niumaterial’s spun yarn is your best choice.

    Do you know about glass fiber yarn?

    Fiberglass yarn is a filament drawn from molten glass through a high-speed rotating nozzle. These filaments are usually between a few microns and tens of microns in diameter, and have the characteristics of high strength, corrosion resistance, high temperature resistance and good electrical insulation. Glass fiber yarn is widely used in many industries due to its excellent performance, such as building materials, aerospace, electronic equipment and composite materials. Especially in the field of insulation materials, glass fiber spun yarn has become an ideal choice with its unique properties.

    Importance of glass fiber yarn in insulation materials

    High electrical insulation

    Glass fiber yarn has excellent electrical insulation performance, can maintain stable insulation effect in high voltage environment, and prevent current leakage.

    High temperature resistance

    Glass fiber yarn can maintain its mechanical properties in high temperature environment, and is suitable for application scenarios that require long-term high temperature resistance.

    Corrosion resistance

    Glass fiber yarn has good tolerance to most acid and alkali solutions, is not easily corroded by chemicals, and prolongs its service life.

    Lightweight and high strength

    Glass fiber yarn has low density and light weight, but high strength, which is easy to transport and install, and reduces the load on the structure.

    Strong processability

    Glass fiber yarn can be used in combination with other materials to make composite materials with different forms and functions to meet diverse application needs.

    Materials used for yarn and its role in insulation materials

    The main raw material of fiberglass yarn is glass, usually alkali-free glass (E-glass) or medium alkali glass (C-glass). These glasses are made into yarns through melting, drawing and other processes, and have the following characteristics:

    Alkali-free glass (E-glass)

    • Composition: The main components are silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), calcium oxide (CaO) and a small amount of boron oxide (B₂O₃).
    • Advantages: It has high mechanical strength, excellent electrical insulation and chemical corrosion resistance, and is suitable for most insulating materials.

     

    Medium alkali glass (C-glass):

    • Composition: It contains a high proportion of sodium oxide (Na₂O) and calcium oxide (CaO), and the other components are similar to alkali-free glass.
    • Advantages: It has good acid resistance and is suitable for insulating materials in acidic environments.

    The role of glass fiber yarn in insulating materials is mainly reflected in the following aspects:

    • Enhance mechanical properties: Fiberglass yarn can significantly improve the mechanical strength and toughness of composite materials, making them more durable.
    • Improve electrical insulation: Glass fiber yarn has excellent electrical insulation properties, which can effectively prevent current leakage and ensure the safe operation of electrical equipment.
    • Improve thermal stability: Glass fiber yarn can maintain its mechanical properties in high temperature environment, ensuring the stability and reliability of insulation materials under high temperature conditions.
    • Increase durability: Glass fiber yarn has good tolerance to most chemicals, extending the service life of insulation materials.

    Specific application cases of yarn in insulation materials

    Power transmission equipment

    • Cable sheath: Glass fiber yarn is often used to make cable sheath, providing additional mechanical protection and electrical insulation layer to ensure the safe operation of cables under high voltage environment.
    • Transformer insulation material: Glass fiber yarn is used as the insulation material inside the transformer, which can withstand high temperature and high pressure to prevent short circuit and leakage accidents.

    Electronic equipment

    • Printed circuit board (PCB): Glass fiber yarn is compounded with epoxy resin to make high-performance printed circuit board substrate, which has excellent electrical insulation and mechanical strength, and is suitable for high-frequency electronic equipment.
    • Radiator insulation gasket: Insulation gasket made of glass fiber yarn is used to isolate the radiator from electronic components, ensuring effective heat conduction without affecting electrical insulation performance.

    Building structures

    • Fireproof and heat-insulating materials: Fireproof and heat-insulating materials made of glass fiber yarn are widely used in building exterior walls and roofs, providing efficient fire protection and heat insulation performance, ensuring the safety and comfort of buildings.
    • Waterproof rolls: Waterproof rolls reinforced with glass fiber yarn have excellent tear strength and weather resistance, and are suitable for waterproofing projects in various complex environments.

    Aerospace

    • Aircraft insulation materials: As the insulation material inside the aircraft, glass fiber yarn can withstand extreme temperature changes and mechanical stress to ensure the safety and reliability of the aircraft.
    • Satellite antenna cover: Composite materials reinforced with glass fiber yarn are used to manufacture satellite antenna covers, which have excellent wave transmittance and electrical insulation, ensuring the stable transmission of communication signals.

    How to choose the right glass fiber for your insulation material

    Choosing the right glass fiber yarn is crucial to ensuring the performance of the insulation material. Here are a few key factors:

    • Application scenario: Choose the right type of glass fiber according to the specific application scenario. For example, alkali-free glass fiber (E-glass) is suitable for most insulation materials, while medium-alkali glass fiber (C-glass) is more suitable for applications in acidic environments.
    • Mechanical performance requirements: Consider the mechanical strength and toughness required by the insulation material, and select glass fiber spun yarn with corresponding characteristics. Generally, high-strength and high-toughness spun yarn is more suitable for high-load environments.
    • Electrical insulation performance: Evaluate the specific electrical insulation requirements of the insulation material and select glass fiber spun yarn with good electrical insulation. Alkali-free glass fiber (E-glass) is particularly outstanding in this regard.
    • Temperature resistance: According to the temperature range of the application environment, select glass fiber spun yarn that can maintain stable performance under high temperature conditions. Glass fiber spun yarn can usually work in a temperature range of -100°C to +450°C.
    • Supplier reputation: Choose suppliers with good reputation and rich experience to ensure product quality and after-sales service. Niumaterial has become the first choice of customers with many years of production experience and strict quality control system.
