There are around 200 employees, of whom 40 people got the college education, we have passed the certificate of ISO9001:2008 Certificates .

Our strong main products as follows :

1) 1,5,2,4-Dioxadithiane 2,2,4,4-tetraoxide (MMDS)
2) Methanedisulfonic acid, Methanedisulfonic acid disodium salt , Methanedisulfonic acid dipotassium Salt
3) 2-Chlorobenzaldehyde,P-Chlorobenzaldehyde,3-Aminophenol and 4-Hydroxybenzaldehyde
4) Methyl 2-Fluoroacrylate and Lawesson’s Reagent


We are the first industrial factory which produce 1 ,5,2,4-Dioxadithiane 2,2,4,4-tetraoxide (MMDS) on MT or Bulk quantity in China, our yearly production capacity will arrive 200MT in the following two years in our plan, our factory start to produce 1,5,2,4-Dioxadithiane 2,2,4,4-tetraoxide (MMDS) in 2016 , we have owned MMDS core production technology with our own Patent ,MMDS is a new type of electrolyte additives for lithium ion batteries, in the production of lithium-ion battery electrolytes, 1,5,2,4-Dioxadithiane 2,2,4,4-tetraoxide (MMDS) can completely replace 1,3-Propanesulfonate (1,3-PS, CAS number: 1120-71-4) ,the battery that add MMDS can greatly improve high temperature cycling performance of lithium-ion batteries, it can also greatly extend the life of lithium batteries ,Applies to batteries, in particular lithium manganese oxide as cathode materials for batteries, MMDS can melt under high temperature of Mn adsorbed on the electrode surface, inhibited the impedance increases, improved cycle characteristics .
