For products with complex shapes, difficult molding and small quantities, it can better reflect its process advantages, which can effectively reduce production costs and improve production efficiency 3. • Good dimensional stability: The linear expansion coefficient is small, and its size changes little under different temperature environments, and it can maintain good stability. This is very important for some application scenarios with high requirements on dimensional accuracy, such as components of precision instruments and equipment, brackets for optical instruments, etc. 1. • Good shock absorption performance: It has a high shock absorption frequency, can absorb and consume a certain amount of vibration energy, has good shock absorption and seismic resistance, and can be used to manufacture some equipment components or structures that require shock absorption and noise reduction, such as vehicle body parts, shock-absorbing supports for bridges, etc.

1. • Rich colors: The surface can be coated with various coatings to make products of various colors to adapt to different use environments and aesthetic needs. It can be used in architectural decoration, landscape design and other fields that have requirements on appearance color. 1. Scope of application • Construction industry: It can be used to manufacture doors and windows, partitions, curtain walls, beams, columns, roof panels, ceilings, stairs,
handrails, balcony railings, shading systems, ventilation ducts, etc. When used in building structures, it can reduce the building's deadweight and improve its earthquake resistance. When used in doors and windows, it has good sealing, thermal insulation, and sound insulation properties, which can improve the building's comfort and energy-saving effects. 1 2 8. • Chemical industry: widely used in the manufacture of equipment such as storage tanks, reactors, pipelines, and fan blades. It can resist corrosion from various chemical media, ensure the safe and stable operation of the chemical production process, and improve the reliability and service life of the equipment. 2 4. • Transportation: suitable for the manufacture of fiberglass boats, bridges, tunnels, automobile body parts, and interior parts of rail transit vehicles. Its light weight, high strength, corrosion resistance, and insulation properties can meet the high-performance requirements of transportation vehicles for materials, reduce deadweight, and improve transportation efficiency and safety. 2 4. • Sewage treatment: can be used to make septic tanks, sewage treatment tanks, sewage pipes, etc. Because of its corrosion resistance, wear resistance, and no secondary pollution, it can be used stably for a long time in harsh sewage environments to ensure the normal operation of the sewage treatment system. 4. • Electrical communication field: As an excellent insulating material, it can be used to manufacture electric poles, cable bridges, antenna covers of communication base stations, etc., to ensure the safe operation of electrical equipment and communication systems, and prevent accidents such as leakage and short circuit. 1 3 6. • Energy field: In wind power generation, it can be used to manufacture blades of wind turbines; in solar photovoltaic power generation, it can be used to manufacture support structures of solar panels, etc., using its advantages of light weight, high strength, and good weather resistance to improve the performance and service life of energy equipment. • Food and beverage industry: Because FRP profiles are non-toxic, odorless, and corrosion-resistant, they meet food hygiene standards and can be used to manufacture equipment parts, storage containers, and transportation pipelines in food processing plants. • Sports and leisure field: It can be used to manufacture seats, fitness equipment, amusement facilities, etc. in stadiums. Its high strength, good weather resistance, and rich colors can meet the needs of different places and users.
