Tired of polycondensation headaches in your polymer lab? 🧪
Unstable vacuum, inconsistent parameters, messy wall sticking and hard‑to‑clean reactors can slow down your polyester & polymer R&D progress.
Huotong’s 1000mL esterification‑polycondensation reaction unit is built to fix these pain points all at once:
🔹 Mirror polished reactor interior: no material adhesion & residual buildup
🔹 Electric lift reactor body design: feeding, sampling and maintenance without removing the reactor lid
🔹 Combined stirring impeller + torque sensor: track reaction state live
🔹 Electric heating + internal cooling coils + mercury vacuum gauge: stable temperature and high vacuum for polycondensation
🔹 PLC touchscreen control: monitor all key parameters, record and trace experimental data
One complete piece of equipment covers the full esterification and polycondensation process. Perfect for polymer and petrochemical labs working on process development and small batch trials.

Another win in our polymer lab!

Our PA‑elastomer (hard‑segment 910) is successfully discharged during 29L Esterification and Polycondensation Reactor testing!
We use PTMG block polycondensation for this formulation, plus sodium hypophosphite as auxiliary to improve thermal anti‑oxidation performance and avoid polymer degradation.
Better heat stability = more reliable performance for elastomer‑related projects.
Feel free to reach out if you want to know more about this PA elastomer grade.
