Methylene Chloride (CH₂Cl₂), also known as Dichloromethane (DCM), is a versatile industrial solvent valued for its powerful dissolving properties and fast evaporation rate. In the polyurethane industry, it is commonly used as a physical blowing agent and processing aid in the manufacture of flexible polyurethane foam, helping to control foam density and improve processing characteristics.
Beyond polyurethane applications, methylene chloride is widely used in adhesive formulations, paint and coating removal, pharmaceutical processing, metal degreasing, aerosol products, and chemical manufacturing. Its excellent solvency allows it to dissolve a broad range of resins, waxes, oils, and polymers while leaving minimal residue after evaporation.
Due to its effectiveness and versatility, methylene chloride is an important raw material across many industrial sectors. However, because it is a hazardous chemical, it should only be handled by trained personnel using appropriate safety precautions.

How to Use
Methylene Chloride should be used according to the specific formulation or industrial process. In polyurethane foam production, it is incorporated in controlled quantities as part of the formulation. Due to its volatility and health hazards, it should only be used in well-ventilated industrial environments with suitable engineering controls and personal protective equipment (PPE).
Storage & Handling
Store in tightly sealed containers in a cool, dry, and well-ventilated area away from heat and direct sunlight. Avoid inhalation of vapors and prevent contact with skin and eyes. Always wear appropriate PPE, including chemical-resistant gloves, eye protection, and respiratory protection where required. Refer to the Safety Data Sheet (SDS) before handling or use.
