Superiority
Jiangsu Dongkai Chemical Co.,Ltd. was set up in AUG., 2016, with registered capital of 10,000,000.00 RMB.It's a comprehensive company engaging in outsourcing, distributing and trading chemical raw materials.The annual sales turnover is more than 30,000,000.00 RMB.
In past 5 years, we have enlarged our business scope to a full range of basic materials which is mainly used in synthetic resins, painting, coating, and other chemical raw material, like Trimethylolpropane, Epichlorohydrin, etc. Therefore we have much experence and huge suppliers in this field in China.
As to Di-Trimethylolpropane, we have high quality of Di-Trimethylolpropane and the output is more than 10,000 MT per year so there is no problem of supplying.
By the way, since the company is near Shanghai Port, the biggest port in China, transportation is very convenient.
