Polyurethane PU PV module frames offer a bunch of advantages over traditional aluminium and metal PV module frames.Polyurethane(PU) composites material have excellent mechanical properties, with axial tensile strengths more than seven times that of traditional aluminium alloys.Strong resistance to salt spray and chemical corrosion. Possessing a high volume resistivity, the encapsulation of PV modules with polyurethane frame greatly reduces the possibility of forming leakage circuits, which helps to reduce the generation of PID potential-induced attenuation phenomena. Improves the power generation efficiency of the panel. Polyurethane frames can also be used in conjunction with waterborne polyurethane coatings, greatly increasing the weather resistance of the frame with very low VOC emissions.

GWELL combines advanced pultrusion technology local and abroad to independently develop and launch hydraulic type pultrusion production lines and caterpillar type pultrusion production lines.It uses well-known domestic and foreign brand components to provide customers with stable and reliable quality,easy operation,and  highly efficient double outputs PU PV specialized frame pultrusion production line.
