Why More PET Factories Switch from Antimony Acetate to ATG Catalyst
Why More PET Factories Switch from Antimony Acetate to ATG Catalyst For PET and polyester producers, catalyst selection is no longer a small raw-material decision. It affects esterification stability, polycondensation rate, color tone, acetaldehyde formation, chip quality, filter life, maintenance frequency, and ultimately the cost per ton of polymer. As PET plants run larger continuous […]
Ethylene Glycol Antimony (ATG): High Performance Catalyst for PET Polycondensation
Ethylene Glycol Antimony (ATG): High Performance Catalyst for PET Polycondensation PET producers are under constant pressure to increase throughput, reduce color drift, control acetaldehyde, and maintain stable intrinsic viscosity while processing larger volumes of bottle-grade, film-grade, fiber-grade, and engineering polyester resin. In continuous PET lines, even small variations in catalyst purity, solubility, dosing stability, and […]
