HCFO-1233zd(Z) (CAS 99728-16-2), chemically known as (Z)-1-Chloro-3,3,3-trifluoropropene, is a next-generation precision cleaning agent developed for the semiconductor, electronics, and aerospace industries. As global regulations tighten on HCFCs (like 141B) and HFCs, this product stands out with its Zero Ozone Depletion Potential (ODP) and Ultra-low Global Warming Potential (GWP < 1). With a moderate boiling point of 39.0°C and a KB value of 34, it provides powerful solvency while ensuring rapid, streak-free drying.
Features Zero ODP and GWP < 1, fully compliant with the Montreal Protocol and F-gas regulations.
Benefit: Future-proofs production against carbon mandates and chemical bans.Non-flammable (No Flash Point) with a balanced KB value effective against oils, fluxes, and particulates.
Benefit: Safe for operators; excellent compatibility with metals and polymers.Extremely low residue (≤ 0.01%) and minimal moisture content (≤ 0.002%).
Benefit: Eliminates secondary rinsing, increasing yield rates for wafers/PCBs.| CAS Number | 99728-16-2 |

Q: What is the difference between 1233zd(Z) and 1233zd(E)?
A: 1233zd(E) boils at ~19°C (gas at room temp), while the Z-isomer boils at 39°C. This makes the Z-isomer a stable liquid at room temperature, ideal for immersion cleaning and vapor degreasing.
Q: Is it compatible with sensitive plastics?
A: It is compatible with most materials like PTFE, PP, and PE. For sensitive resins like Polycarbonate (PC) or ABS, we recommend a small-scale compatibility test before full implementation.
Q: Why is it the best 141B replacement?
A: It matches the cleaning power (solvency) of 141B while being non-flammable and having near-zero impact on the ozone layer and global warming.
