Honeywell HFO-1234ze blowing agent is fully compliant with the EU F-Gas regulation. As a gas material at room temperature, this molecule has diverse applications including as a blowing agent for polyurethanes, polystyrene and other polymers; as well as an aerosol propellant.
What are the flame limits of Honeywell HFO-1234ze?
Honeywell HFO-1234ze blowing agent exhibits narrow vapour flame limits at elevated temperatures (>28°C). At 30°C, Honeywell HFO-1234ze blowing agent exhibits flame limits LEL/UEL at 7.0/9.5 volume percent in air.
What is the difference between CFC-12 and HFO-1234ze?
• Based on blowing potential at equimolecular com- parison, HFO-1234ze requires almost the same mass as CFC-12 but 15% more than HCFC-142b and HFC-134a and 70% more than HFC-152a.
How is HFO-1234ze blended with DME?
For cost and processing reasons, HFO-1234ze has been blended by the sup- plier with DME. At a later stage DME has been di- rectly injected as a co-blowing agent; and • Trials/Testing – Before the trials, the host company installed an air powered booster pump to support the trials.
