Trans-1,2-Dichloroethylene, Next generation solvent for precision cleaning industry. To help the user to escape from the continuous price increasing of n-Propyl Bromide, Unistar is working on a new project to remove or increase the flash point of 1,2-Trans. Candidates include Methylene Chloride, HFC products. We have been successfully increase the flash point to 50 degree C. Our goal is to create a affordable, steady supplying product to cleaning industry.

Hot News
n-PB price keep jumping.
Because of the shortage on bromine element, price of n-PB keep going up. It breaks $2.00/lb recently. n-PB is losing its price advantage.
Unistar will expand its 1,2-trans production capacity to 5000MT/year. In the new plant, a new production line of PERC will be setup simultaneously. the expected production capacity of PERC will be 10000MT/year

EPA SNAP Approved solvent in Aerosol, Electronic, Metal and Precision Cleaning and some of Foam Blowing Formulation.
