What are the concerns regarding purity of hfc 134a?

Concerns regarding the purity of HFC-134a (tetrafluoroethane) primarily stem from the presence of impurities that can affect its performance and environmental impact. Impurities can arise from manufacturing processes or degradation over time, potentially leading to reduced efficiency in refrigeration systems and increased emissions of harmful substances. Additionally, lower purity levels can cause compatibility issues with lubricants and other system components, risking system failure. Ensuring high purity is crucial for optimizing system performance and minimizing environmental harm.
