Fiberglass reinforced plastic (FRP) profiles are made from glass fiber and resin as core raw materials through a pultrusion molding process. They possess the following significant performance characteristics:
• High strength-to-weight ratio: Tensile strength reaches 300-500 MPa, density is only 1/4 that of steel, and weight is reduced by 60%-70% for the same strength, facilitating transportation and installation.
• Excellent corrosion resistance: Excellent performance against corrosive media such as acids, alkalis, salts, and organic solvents. Service life in harsh environments such as chemical plants, marine environments, and wastewater treatment plants is 5-10 times that of traditional metal materials.
• Excellent insulation performance: Volume resistivity > 10¹⁴ Ω·cm, dielectric strength > 20kV/mm, suitable for high-voltage power equipment and electronic insulation applications.
• Outstanding thermal stability: Operating temperature range -50℃ to 120℃, coefficient of thermal expansion is only 1/2 that of steel, exhibiting superior stability in environments with drastic temperature changes compared to metal materials.
