R1234ze(E) (trans-1,3,3,3-Tetrafluoropropene, CAS 29118-24-9) is an HFO with zero ODP and a GWP of less than 1. Its slightly higher boiling point vs R1234yf makes it ideal for medium-temperature chillers, high-temperature heat pumps, XPS/PU foam blowing, and low-GWP aerosols.
As a China-based refrigerant exporter with 37 years of experience, Dalian Tongtai (TCoolGas) supplies R1234ze(E) to 50+ countries with full SDS / TDS / COA per batch. We support mixed-SKU container consolidation and provide third-party re-test reports within 24 hours on request.
Centrifugal chillers, especially HFC-134a retrofits.
XPS/PU insulation foam.
Low-GWP technical aerosol propellant.
High-temperature industrial heat pumps.
