Polycarbonate has better impact strength while lighter, particularly excellent in transparency, it is widely used for products that require optical performance. However, UV-cut property is lowered, yellowing of Polycarbonate occurs by UV, fell infrared cut ability, it is difficult to cut off the heat in the summer, there is a difficult disadvantage to maintain the internal radiant heat in the winter. The improved optical performance polycarbonate has UV cut resistance or infrared cut capacity has developed in order to supplement such disadvantages.
