  In 1996,in order to improve the product quality of thiourea dioxide,our company has developed pure deionized water with Jinlin Institute of Chemical Technology, which has strengthened the stability of thiourea dioxide, has avoided the danger in transport. In the same year, our company received ISO9002n quality system certification.
