Industrial Grade 99% Dichloromethane DCM Methylene Chloride CAS 75-09-2 Bulk Wholesale

Industrial Grade Dichloromethane, also known as Methylene Chloride and shorted as DCM, is a widely applied halogenated organic solvent with fixed CAS number 75-09-2. It is produced through methane chlorination reaction followed by multiple precise rectification and impurity removal procedures. Our factory strictly controls rectification temperature, fraction separation and post-treatment processes to guarantee stable purity above 99%, which can fully meet the mass production demands of pharmaceutical extraction, coating, metal cleaning, polyurethane foaming, adhesive manufacturing and printing ink industries around the world.

The finished product is colorless transparent volatile liquid with a faint ether smell. Its core advantage lies in powerful universal solvency. It can rapidly dissolve all kinds of synthetic and natural resins, mechanical grease, printing ink, old paint layers, polyurethane raw materials and rubber particles. Different from flammable solvents such as acetone, ethyl acetate and methanol, DCM has no flash point under normal temperature and pressure, which greatly reduces fire hazards in closed factories and becomes the preferred safe solvent for large-scale industrial cleaning and extraction processes.

With a low boiling point around 40℃, DCM volatilizes quickly at room temperature and leaves no trace on the surface of workpieces after evaporation. In pharmaceutical production, it serves as an ideal extraction solvent for active pharmaceutical ingredients and plant extracts. After extraction, it can be easily separated from target products via mild heating evaporation without damaging product activity. In coating and printing industries, it is the key raw material of high-efficiency paint remover and ink diluent, accelerating film forming speed and upgrading the smoothness of finished coatings. For precision hardware, optical lenses and circuit board processing factories, DCM is used for degreasing to thoroughly remove soldering flux, lubricating oil and wax contaminants without causing corrosion to workpiece surfaces. Besides, it acts as an important foaming auxiliary agent for rigid polyurethane thermal insulation foam materials.

We implement full-process strict quality testing for each batch, detecting purity, water content, free acid and non-volatile residues to eliminate equipment corrosion and defective finished goods triggered by excessive impurities. All packages pass UN dangerous goods certification, including sealed 250kg galvanized steel drums, 1000L IBC intermediate bulk containers and ISO tank containers for ultra-large bulk orders. Every shipment is equipped with official COA test report, MSDS safety data sheet and dangerous goods transport certificate to support customs clearance in all countries.

During storage and operation, operators must wear chemical-resistant gloves and gas masks to avoid long-term inhalation of volatile vapor. The warehouse needs to keep low temperature and good ventilation, far away from high-temperature heat sources, strong oxidants and alkaline chemicals to prevent unexpected chemical reactions. We provide small 25L drum trial samples for customer formula testing, as well as stable long-term bulk wholesale with sufficient spot inventory and direct factory competitive pricing to serve global chemical purchasers.
