Glass fiber performance characteristics

Label film

The performance characteristics of glass fiber mainly include the following aspects:

1. Physical properties
   Lightweight and high strength:
   Glass fiber has an extremely low density, but its strength is comparable to that of steel, while its weight is only 1/4 to 1/5 of that of steel. This gives glass fiber a unique advantage in application scenarios that require lightweight but high strength.
   Dimensional stability:
   Glass fiber products have good dimensional stability, are not easily affected by changes in temperature and humidity, and can maintain a stable shape and size.
2. Thermal properties
   High temperature resistance:
   Glass fiber has good thermal stability and can work for a long time in a high temperature environment without deformation or damage. It has a high melting point, and it is generally believed that the softening point is between 500 and 750°C, and the boiling point is about 1000°C.
   Low thermal conductivity:
   Glass fiber has a low thermal conductivity, so it has good thermal insulation performance and is suitable for occasions that require thermal insulation.
3. Chemical properties
   Corrosion resistance:
   Glass fiber has good resistance to chemical corrosive media such as acids and alkalis, so it is suitable for engineering construction in corrosive environments such as chemical industry and sewage treatment.
   Chemical stability:
   The chemical stability of glass fiber depends on its chemical composition, medium properties, temperature and pressure, etc. It is stable to most inorganic compounds and is almost unaffected by organic solvents.
4. Electrical properties
   Good insulation:
   Glass fiber is a non-conductive material with good insulation properties. It is suitable for insulation and support structures of electrical and electronic equipment.
5. Mechanical properties
   High strength:
   Glass fiber has a high tensile strength, which can reach 6.36.9g/d under standard conditions and 5.45.8g/d under wet conditions. This makes it an ideal reinforcing material for reinforcing composite materials such as plastics and rubber.
   Good elasticity:
   Glass fiber has a large elongation within the elastic limit and high tensile strength, so it can absorb large impact energy and has good impact resistance.
6. Other properties
   Low hygroscopicity:
   Glass fiber has low water absorption, which is 1/20~1/10 of natural and synthetic fibers. This helps to keep the product dry and stable.
   Good processability:
   Glass fiber can be processed into products in different forms such as strands, bundles, felts, and woven fabrics, which are easy to select and process according to needs.
   Transparency:
   Glass fiber is transparent and can transmit light, and is suitable for occasions where light transmission is required.
   Good bonding with resin:
   Glass fiber has good bonding with resin and can form a strong composite material structure.
   Environmentally friendly and recyclable:
   Glass fiber is an inorganic non-metallic material that does not release toxic substances and can be recycled, which is beneficial to environmental protection.
   In summary, glass fiber has multiple performance characteristics such as light weight and high strength, high temperature resistance, corrosion resistance, good insulation, high strength, good elasticity, low hygroscopicity, good processability, transparency, and good bonding with resin. These characteristics make glass fiber have broad application prospects in many fields.
