Company introduction

Boram Chemetal Co., Ltd. has been developed rather than depressed under the IMF, through technical development & acceleration employment. The word of Chemetal is combined chemistry with metal.

Concerning environment with especially developed the technology of recycling wastes, and localization of optical coating material is increasing the competitiveness in glasses industry. The technology of Fused Silica was able to localized raw materials of the fireproof nozzle, including foreign currency saving & supporting national competitiveness.

As these results, we were designated as promising small& medium industry company(1999.9), certificated the venture company(1999.11), founded the central research institute(2000.7) and also designated company with promising advanced technology(2000.12) We will continue to research and develope basic materials, is related with glass industry.
