Polymer & Resin Analysis

Accurate analysis of polymers, resins, and adhesives is essential for maintaining product quality, process consistency, and regulatory compliance.

From acid value and hydroxyl number to moisture content and isocyanate determination, modern analytical methods ensure precise control of critical material properties.

Automated titration and Karl Fischer techniques provide reliable, repeatable results for demanding industrial quality control applications.
