Sumika PC Uptical raw materials
The Sumitomo Group of Japan and the Dow Chemical Company of the United States even produced PC raw materials many years ago. After that, they exclusively obtained the authorization of the manufacturing technology formula and merged and established Sumitomo Chemical Polycarbonate Corporation to supply high-quality raw materials for the global PC product manufacturers. At the beginning of its establishment, Li Hao was authorized by Japan's Sumitomo Chemical Polycarbonate Co., Ltd. to sell optical-grade PC raw materials in Asia. Its market is mainly for the manufacture and use of optical-grade safety lenses and other related industries in Asia at home and abroad. Because of its high yield rate, stable quality and reasonable market price, it is highly praised by PC customers worldwide.
