R134a, chemically known as 1,1,1,2-Tetrafluoroethane (CAS No: 811-97-2), is a hydrofluorocarbon (HFC) refrigerant that has played a pivotal role in modern cooling technologies. Its widespread adoption stems from its favorable properties, including being non-toxic, non-flammable, and a non-ozone-depleting substance, making it a safer alternative to earlier CFC refrigerants like R-12.

As a chemical intermediate and a primary refrigerant, R134a finds extensive use in a variety of applications. Its most prominent application is in automotive air conditioning (AC) systems, where it efficiently provides cooling for vehicle interiors. Beyond vehicles, R134a is a common choice for medium and high-temperature refrigeration systems, including domestic refrigerators, commercial display cases, and industrial chillers. Its chemical formula, CH2FCF3, and molecular weight of 102.03 g/mol contribute to its specific thermodynamic characteristics that are well-suited for these cooling tasks.

When considering the purchase of R134a refrigerant gas, understanding its purity and packaging is crucial. High-purity R134a, typically 99.99%, ensures optimal system performance and longevity. It is commonly supplied in disposable cylinders of various sizes, such as the popular 13.6kg (30lb) cylinder, which is convenient for both professional technicians and bulk buyers. If you are looking to buy R134a refrigerant, sourcing from a reliable manufacturer and supplier in China can offer competitive pricing and assurance of product quality.

Safety in handling R134a refrigerant gas is paramount. While non-flammable under normal conditions, it is still a gas that requires careful handling to avoid inhalation of high concentrations, which can cause dizziness or asphyxiation. It is also important to avoid exposing cylinders to excessive heat or open flames. Always ensure adequate ventilation when working with R134a and use appropriate personal protective equipment (PPE). When searching for R134a refrigerant price, remember to factor in the quality, packaging, and the supplier's reputation. For businesses in need of a consistent supply, partnering with a chemical manufacturer that specializes in refrigerants like R134a can provide significant advantages in terms of cost and availability.

As the industry evolves, R134a faces scrutiny due to its Global Warming Potential (GWP). While it is a significant improvement over CFCs and HCFCs, its GWP is still considerable. This has led to regulations and a market shift towards lower-GWP alternatives in some regions. However, for many existing applications, R134a remains a vital and accessible refrigerant. For procurement managers sourcing this essential chemical, understanding its properties, applications, and responsible handling practices from a trusted supplier is key.
