Raw Material: Dichloromethane (Methylene Chloride) Dichloromethane, also known as DCM, methylene chloride, or methylene bichloride, is an organic compound commonly used as a solvent in various industrial applications. Chemical Properties: Chemical Formula: CHCl CAS Number: 75-09-2 Appearance: Colorless, transparent liquid Odor: Irritating ether-like odor with a sweet, chloroform-like scent Solubility: Dichloromethane is slightly soluble in water and fully soluble in ethanol and ether. It exhibits low polarity and is miscible with many organic solvents, making it versatile for various applications. Physical Properties: Under normal usage conditions, dichloromethane is a non-flammable, low-boiling solvent. It serves as an effective replacement for flammable solvents such as petroleum ether and ether, particularly in environments where safety is a concern. However, caution is advised when vapor concentrations become elevated, especially in high-temperature air.
HFC-245fa, or 1,1,1,3,3-pentafluoropropane, is a third-generation alternative blowing agent designed to replace chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) in various applications. It is primarily utilized as a blowing agent for rigid polyurethane (PU) foam, which is extensively used in refrigerators, cold storage, and building boards. Additionally, HFC-245fa serves as a refrigerant, effectively replacing R-123 and R-22 refrigerants in central air conditioning systems (chillers). Quality Index: Purity: 99.8% Moisture (% w/w): 0.0020 Acidity (as HCl, ppm w/w): 0.0001 Evaporation Residue: 0.01 Color: Colorless liquid HFC-245fa's high purity and low moisture content make it suitable for a wide range of industrial applications, ensuring optimal performance and reliability.
