Are there any restrictions on using HFC-134a for foam blowing?
To date, HFC-134a has been SNAP approved for all markets where its applicability is known. However, Arkema suggests that the current lists be consulted (at www.epa.gov/ozone) since these do change frequently, with either additions or deletions. We would be happy to assist a determination in a specific market or assist preparation of a new SNAP petition, if necessary.
