For a long time, photovoltaic power stations have been using traditional metal frame components. However, under the long-term action of high voltage, PID (Potential Induced Degradation) effect occurs in these components, leading to fatal power attenuation and a sharp decline in power generation, causing significant economic losses. Therefore, there have been rounds of attempts within the industry to develop solutions to reduce the risk of PID effects. Non-metal frames may be a very good solution.

     Jufa New Materials' aliphatic polyurethane resin, through material innovation, has addressed the problems of traditional resins, such as "weather resistance relying on post-treatment" and "difficult to balance mechanical properties", providing more efficient and sustainable solutions for outdoor high-load scenarios like photovoltaics and marine engineering.

1.Advantages of UV resistance and no need for painting

Traditional aromatic resins are not resistant to ultraviolet rays and thus require a protective layer to be sprayed later (such as polyurethane paint) to extend their lifespan, which increases the complexity of the process and the cost. However, the aliphatic polyurethane pultrusion resin from Polyflex New Materials has passed TUV-SUD certification. Its molecular structure possesses natural UV resistance, and it can maintain stable physical and chemical properties even when exposed to ultraviolet rays, humidity, salt spray, and temperature cycling for a long time. Its weather resistance directly matches that of polyurethane paint, eliminating the need for spraying, reducing processing costs while ensuring long-term aesthetics and functional integrity in outdoor scenarios.

2. Mechanical properties and high load-bearing compatibility

This resin not only breaks through the bottleneck of weather resistance, but also has core mechanical indicators such as tensile strength, bending strength and impact resistance that are comparable to those of aromatic polyurethanes. The bending strength can reach 800 to 1200 MPa, meeting the rigidity requirements of high-load scenarios such as photovoltaic frames and offshore wind turbine components. Moreover, it does not compromise mechanical properties due to weather resistance, achieving a dual balance of "strength - durability".

3. Enhancement of economic performance throughout the entire life cycle

  Cost reduction and efficiency improvement: The no-spraying process shortens the production process, reduces processing energy consumption and labor costs.

Long-lasting maintenance-free: The anti-aging property extends the service life of the components (estimated to increase by more than 30%), reducing the costs of replacement and maintenance due to corrosion and cracking.

Environmental compliance: Avoid VOC emissions during the spraying process, in line with green manufacturing standards.

Polyurethane pultrusion process - Polyurethane energy-saving doors and windows

      The traditional window and door profiles consume a large amount of energy during application and have poor fire resistance, which no longer meets the requirements of green buildings. The polyurethane composite material pultrusion profiles represent the inevitable trend for the development of energy-saving window and door profiles in the future.

Glass Fiber Reinforced Polyurethane (abbreviated as GRPU) is a high-performance composite material. It is produced through injection, impregnation and extrusion processes. Due to its fiber reinforcement, its compressive, tensile and bending strength are all very high.

Ultra-low heat conduction - Super energy efficiency

This system does not require any breakaway joints or steel liners. The thermal conductivity of its profiles is excellent: when the entire window design has a K value of 2.0, the energy-saving performance of this system's double-glazed glass exceeds that of the triple-glazed glass made of aluminum alloy. When combined with three layers of glass, it can meet the standard of a passive house with a K value of 0.9W/m2•k.

2. Reliable low-temperature resistance capability

The glass fiber reinforced polyurethane pultrusion profiles have passed the physical performance comparison test of being frozen and thawed 100 times at -40℃, ensuring their mechanical properties in extremely low temperatures.

3. Excellent mechanical properties

      Continuous fibers significantly enhance the strength, hardness and elastic modulus (bending modulus can reach 51 GPa) of polyurethane profiles. Without the need to insert reinforcing steel, stable hollow glass bearing can be achieved.

    The use of polyurethane winding composite material technology to manufacture electric poles and 5G communication towers has the advantages of being lightweight (convenient for installation and transportation), high strength (long lifespan), corrosion resistance (less maintenance), low product cost, and environmentally friendly manufacturing process. It solves problems such as heavy weight of metal towers, difficulty in installation and transportation, large occupied area during installation, need for annual maintenance due to corrosion, and environmental pollution during production. It reduces system costs and improves product quality.
