Potentiometric titration of carboxyl end groups quantifies thermal hydrolytic history in rPET lots, revealing latent processing damage and driving lot pricing.
Non-aqueous titration kinetics validate acidic volatile counts in recycled polymers, preventing extrusion screw corrosion and processing degradation.
High temperature non-aqueous titration strips volatile carboxylic acids from hot PE melt into organic media to quantify corrosion risks and thermal stability.
Thermal desorption titration quantifies non-aqueous volatiles in rPET down to 2.5 ppm when cryogenic milling eliminates diffusion limits and baseline drift is corrected.
Expertise is a utility, not a secret. sentiention™ publishes its working knowledge as open reference: intelligence layer covering the materials it sources, the markets it enters, and the reference that serves both.
