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: â?¥99.8% Moisture (% w/w): â?¤0.0020 Acidity (as HCl, ppm w/w): â?¤0.0001 Evaporation Residue: â?¤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.
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: CHâ??Clâ?? 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.
Perchloroethylene, commonly known as PERC or tetrachloroethylene, is a versatile solvent widely utilized across multiple industries. It is particularly renowned for its applications in dry cleaning operations and metal manufacturing, where it serves as an effective cleaner and degreaser. Chemical Properties: Other Names: PERC, PCE, and tetrachloroethylene CAS Number: 127-18-4 Chemical Formula: C2Cl4 Appearance: Colorless, non-flammable liquid Odor: Sweet, ether-like aroma Key Applications: Dry Cleaning Clothes: PERC is primarily used as a solvent in the dry cleaning industry, effectively removing stains and dirt from fabrics. Degreasing and Cleaning Metal Parts: In metal manufacturing, perchloroethylene is employed to degrease and clean metal components, ensuring optimal performance and quality. Finishing Product for Textiles: It is used as a finishing agent in the textile industry, enhancing the appearance and durability of fabrics. Oil and Fat Extraction: PERC is also utilized in the extraction of oils and fats, making it valuable in various food processing applications. Intermediate in Synthesis: Perchloroethylene serves as an intermediate in chemical synthesis, playing a crucial role in the production of various chemical compounds.
ABC Dry Powder Fire Extinguishers utilize mono ammonium phosphate-based dry chemical powders, designed for multipurpose use on Class A, B, and C fires. Available in concentrations of 40% and 90%, these extinguishing agents are SABS approved, ensuring reliability and effectiveness. Applications: Class A Fires: The dry chemical powder insulates Class A fires by melting at approximately 350-400 degrees Fahrenheit. Class A fires typically involve common combustible materials such as wood, paper, or trash. Class B Fires: For Class B fires, the powder effectively interrupts the chain reaction by forming a coating on the burning surface. Class B fires involve flammable liquids or gases, including gasoline, oil, propane, and natural gas. Class C Fires: ABC dry powder is safe and effective for Class C fires, as it is a non-conductor of electricity. Class C fires typically involve live electrical equipment, which requires extinguishing agents that do not conduct electricity, unlike water. It's important to note that electricity can also cause Class A and B fires. Inappropriate Uses: ABC dry chemical powder should not be used on chlorine or oxidizer fires, as the resulting chemical reaction can lead to explosions or the release of toxic gases. Water is recommended for these situations. Additionally, it is ineffective for certain metal fires (Class D) and cooking oil fires (Class K). Due to the corrosive nature of ABC dry chemical powder, it is not advisable to use it around aircraft or sensitive equipment.
