Blowing Agent - We Can Meet Your Application and Performance Requirements

Blowing Agent Products

A-Gas supply two of the standard blends used to expand foam and provide insulating capability. With an ozone depleting potential of zero and a boiling point similar to HCFC 141b, 365/227 (87:13) and 365/227 (93:07) are ideal foam blowing agents. 365mfc can be supplied in its pure state, however it is typically blended with R227ea to ensure a non-flammable mixture. We can offer customised blends to meet your application and performance requirements.
