Carbonate additives

HANKANG has been focusing on the production and sales of VC and FEC for more than 20 years. The newly invested Jiangsu HANKANG Electronic Materials Co., Ltd. adopts a new generation of automated, continuous distillation and melt crystallisation combination process to efficiently produce extremely high purity VC and FEC, and continues to provide customers with high quality products and services. The company develops, produces and sells other carbonate additives: vinyl ester ethylene carbonate (VEC), ethylene bicarbonate (EBC) and difluorinated ethylene carbonate (DFEC), which have been delivered to customers in bulk. The company plans to continue to develop new carbonate additives and provide customised services to customers.
