Polyurethane Pultrusion Fiberglass Solar Panels Mounting Bracket Solar Structure
Polyurethane pultruded composite profile photovoltaic support has high strength, corrosion resistance and good insulation performance. Using it as a solar support can provide a strong guarantee for the safety of photovoltaic power generation and the application of harsh environments.
It is suitable for the installation of photovoltaic support, power station power generation, wind power, thermal power, photovoltaic fields, construction sandalwood, electromechanical and other related equipment.
1. Corrosion resistance
Polyurethane composite materials have good corrosion resistance, and can withstand the corrosion of various gas and liquid media such as acids, alkalis, organic solvents and salts to varying degrees.
2. Lightweight, high strength, good toughness, can hold nails
Since the photovoltaic bracket of polyurethane composite material is produced by pultrusion process, the fiber content can reach about 80%, so whether it is composited with other resins or with other resins Compared with metallic materials, the longitudinal strength is quite high.
3. Good aging resistance and long service life
Thanks to the high fiber content and the characteristics of polyurethane itself, the polyurethane composite material photovoltaic support has excellent anti-aging performance and greatly prolongs the service life.
4. Good flame retardant performance
Polyurethane photovoltaic support has good flame retardant performance, and its oxygen index can reach more than 32%, which greatly reduces the risk of fire.
Advantages of Polyurethane vs Polyester Resins
1. Increased Strength
2. Improved Transverse properties
3. Highest fiber volume
4. Higher specific strength and stiffness
5. Reduced wall thickness (weight savings)
6. Stronger profiles spanning greater distances
7. Excellent impact resistance (Polyester has poor impact resistance in comparison)
8. Excellent abrasion resistance
9. Easy fabrication
10. Excellent screw pull out strength (compared to traditional polyester pultrusion
11. Much lower smoke generation than Polyester or Vinyl Ester
12. Excellent corrosion resistance
13. No Styrene emissions, no peroxides, NO VOCs
