With excellent performance, lower price, low-carbon environmental protection and many other advantages, composite frame has a very broad application prospect in the photovoltaic industry.

Photovoltaic frame is an important part of the module, which is mainly used to fix and seal the frame structure material of the photovoltaic module, which has a great impact on the life of the module and has high requirements for weather resistance.

Through the material and molding process of polyurethane pultruded frame, composite frame with stronger mechanical properties, lighter weight, better insulation, higher stability and other excellent characteristics can be provided. At the same time, in response to different climate and environmental challenges, the composite polyurethane material also has excellent salt spray resistance, PID resistance, panel sealing, wind pressure/snow pressure resistance, etc., escorting a variety of outdoor applications. In particular, polyurethane composites can significantly reduce the carbon emissions of photovoltaic frames throughout their life cycle compared to traditional aluminum alloy frame materials.

At present, the demand for polyurethane composite frames in the international photovoltaic market is growing at an annual rate of 20%, and the frame market is expected to reach 100 billion yuan in 2028. If all use polyurethane composites, 1 million tons of polyurethane per year will be used.
