Protect reaction stability
Control moisture to reduce variability in transesterification and downstream polymerization.
PBT APPLICATION
DMT for stable PBT production
PBT performance depends on more than headline purity. Moisture, acid value, color and trace impurities influence process stability and final resin quality.
OVERVIEW
Qualification priorities
Translate polymerization risks into measurable feedstock controls.
Monitor hydrolysis-related risk
Use acid value with moisture and storage history, rather than as an isolated metric.
Protect color and performance
Evaluate ash, metals and organic trace impurities against resin requirements.
Validate across batches
Compare representative samples and shipment COA data before recurring supply.
