Import Blowing Agents Hfc-245fa Pentafluoropropane — Buy in Bulk from Supplier in China

HFC-245fa pentafluoropropane is a hydrofluorocarbon blowing agent with the chemical formula CF3CH2CHF2 and a molecular weight of 134.05 g/mol, supplied by Hangzhou Sidewalks Chemical Co., Ltd. from their location in Quzhou, Zhejiang Province, China. The product operates with a boiling point of 15.3 degrees Celsius and a vapour pressure of 123.5 kPa at 25 degrees Celsius, making it suitable for low-temperature foaming processes. Its ozone depletion potential is zero, and its global warming potential of 1,020 (GWP100) positions it as a transitional option in refrigerant and insulation applications.

The material is a colourless liquid at room temperature with a mild ethereal odour, classified as non-flammable with an ASHRAE safety classification of A1. HFC-245fa contains no chlorine or bromine atoms, which eliminates ozone layer depletion concerns associated with earlier HCFC blowing agents. Typical commercial grades achieve purity levels of 99.5 per cent or higher, with moisture content controlled below 50 ppm to prevent hydrolysis during foam production. Acid content, measured as HF equivalent, is typically maintained below 1 ppm to protect catalyst systems and metal surfaces in processing equipment.

Primary applications include rigid polyurethane foam for construction insulation panels, spray foam systems, and appliance insulation where thermal conductivity values of 0.020 to 0.025 W/mK are achieved in the finished foam. The automotive sector uses HFC-245fa in dashboard and seating foam formulations, while the HVAC industry employs it in commercial refrigeration and air conditioning systems. Buyers should confirm with Hangzhou Sidewalks Chemical Co., Ltd. the exact packaging specifications, typical MOQ, and available Incoterms, as these details are not stated in the listing. The supplier's trust tier is registered as harbor, and their response rate is currently showing zero per cent, so direct communication is advisable to establish lead times and sample availability.

Hangzhou Sidewalks Chemical Co., Ltd. is located at Room 2006, Building A, Yigao Square, Quzhou, Zhejiang Province, 324000, China, placing the company in a region with established chemical manufacturing infrastructure approximately 250 kilometres southwest of Hangzhou. The supplier holds a harbor trust tier designation on the platform, with a response rate currently recorded at 0.00 per cent and an average response time of zero hours, indicating no recent engagement through the platform messaging system. The company specialises in chemical products including blowing agents, though the listing provides no additional information about their manufacturing capabilities, certifications held, years in operation, or client base.

The source description positions the company as offering HFC-245fa for refrigeration and foaming applications, but does not specify whether they are a manufacturer, distributor, or trading company. No information is provided about production capacity, warehouse facilities, quality control procedures, or export experience. Buyers should verify directly with Hangzhou Sidewalks Chemical Co., Ltd. whether they hold ISO certification, their standard export packaging for hazardous materials, and their experience with international shipping documentation for fluorinated gas products. The absence of response data suggests potential challenges in communication, making direct email or telephone contact a priority for serious enquiries.
