When Midea, a leading electrical appliance company, is developing air conditioning panels, it needs an acrylic sheet with high transparency and high toughness, and the impact resistance and transparency of the highly transparent acrylic sheet on the market can not meet customer requirements, so it found us Donghua Optoelectronics, hoping to solve their problems. Solution: Due to the low toughness of the conventional acrylic plate, the tensile degree of the panel is weak and easy to break, and the transparency will be reduced when the toughness is increased. We have modified the acrylic raw materials and extrusion process for many times, enhancing its toughness without reducing its transparency, and finally reaching the customer's standards.
