Using TGA for Batch-to-Batch Consistency in Polymer Blends
Using TGA for Batch-to-Batch Consistency in Polymer Blends
Consistent product quality starts with reliable thermal analysis. Thermogravimetric analysis (TGA) helps QA/QC teams compare polymer batches by monitoring three key parameters:
✅ Decomposition temperatures — identify changes in thermal stability.
✅ Mass loss at specific temperature stages — detect variations in polymer, additive, and filler content.
✅ High-temperature residue — evaluate consistency in inorganic fillers and ash content.
For meaningful batch comparisons, standardize sample mass, crucible type, atmosphere, gas flow, heating rate, and temperature program. Under consistent test conditions, TGA curves can help identify moisture, formulation variations, and unexpected residue.
Reliable results start with reliable consumables.
CeramXpert supplies compatible thermal analysis consumables, including aluminum pans and lids, alumina crucibles, and sample pans for leading thermal analysis platforms.
