LG Chem develops PC/ASA material to replace metal in solar panel frames
Source:Adsale Plastics Network    Editor:JK    Date:08.Nov.2021

LG Chem has developed a plastic material that can replace the metal in solar panel frames for the first time in Korea and starts full-scale market penetration. LUPOY EU5201, a PC/ASA flame retardant material that maintains the material shape even during temperature changes due to its low thermal expansion levels, using their proprietary technology and manufacturing method.


Heat resistance and strong durability against corrosion are required as the materials are exposed outside for a long time, such as on exterior walls or the roof where there is direct sunlight. Solar panel frames account for about 10% of solar panels, and are mainly made of aluminum alloy.


LG Chem has developed an engineering plastic that can replace the metal in solar panel frames.

LUPOY EU5201 is a high-performance engineering plastic material that supplements the mechanical properties of general plastics by adding glass fiber to polycarbonate compounds. It has the same level of durability as existing aluminum, but is half the weight.


Also, it has good dimensional stability that maintains its shape even in temperature changes, so it is not easily deteriorated or deformed by the external environment. The chemical decomposition caused by ultraviolet rays exposure has been reduced, which has significantly improved the lifespan of the product compared to general plastics, and the color remains the same even after long-term exposure to ultraviolet rays.


LG Chem has secured mass production capability during the first half of this year and started selling products in full-scale in the third quarter. Starting with the supply for solar panel frames, the Company plans to expand the application of materials to interior and exterior materials of automobiles in the future.


Steven Kim, Leader of the Engineering Materials Division at LG Chem, stated, "Solar panel frames made of plastic have many advantages that differentiate them from existing frames, such as ease of installation, and therefore has great market potential."
