Difluoromethane Uses
Difluoromethane (HFC-32) is a refrigerant with zero ozone depletion potential (ODP).
It forms an azeotropic mixture with pentafluoroethane (known as R-410A), serving as a replacement for chlorofluorocarbons (CFCs, e.g., Freon) in new cooling systems, particularly as an alternative to HCFC-22 (R-22). This blend is widely used in medium- and low-temperature mixed refrigerant applications.
Although it has zero ODP, difluoromethane has a high global warming potential (GWP)—approximately 550 times that of carbon dioxide over a 100-year timeframe.
What are the primary applications of Difluoromethane (HFC-32)?
Difluoromethane (HFC-32) is a refrigerant with zero ozone depletion potential (ODP). It is commonly mixed with pentafluoroethane to form R-410A, which serves as a replacement for older CFCs like Freon, specifically as an alternative to HCFC-22 (R-22) in medium- and low-temperature mixed cooling systems.
Where are your strategic inventory hubs located?
Strategic inventory hubs are maintained at Qingdao, Tianjin, and Longkou port warehouses. Over 1,000 metric tons of stock are consistently kept available to ensure rapid and reliable shipment fulfillment.
What certifications back your quality and compliance standards?
The processes and supply chain operations are triple-certified under REACH, ISO 9001, and FMQS standards. This ensures strict compliance with global hygiene regulations and guarantees high customs clearance success rates, such as 100% success for Russian imports.
What flexible payment terms do you offer for chemical purchases?
We support multiple payment solutions including LC (sight/term) and TT (20% advance + 80% upon shipment). Specialized payment schemes are also available, such as a 90-day LC for South American markets and a 30% deposit + BL payment plan for the Middle East.
How does your supply chain minimize logistics costs and manage custom packaging?
We utilize Flexitank technology to achieve a 12% cost reduction for products like ethylene glycol compared to traditional drum packaging. For construction-grade calcium formate, we utilize moisture-resistant 25kg woven PP bags. Direct liquid chemical shipments are managed via dedicated ISO TANK solutions.
What risk mitigation and after-sales support protocols do you provide?
We provide real-time GPS tracking for all container shipments alongside third-party inspection services at destination ports. Furthermore, customers benefit from a 30-day quality guarantee with replacement or refund options, and complimentary temperature monitoring loggers for reefer container shipments.
