Dichloromethane Packaging Information:
250kg*80drums,20ton/FCL;
270kg*80drums,21.6ton/FCL;
26ton/ISO TANK.
Dichloromethane /methylene chloride applications:
Dichloromethane's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes.
In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings.
Used for grain fumigation and refrigeration of low pressure freezer and air conditioning unit,like Refrigerant-30; Freon-30; R-30.
Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams.
