COA vs SDS: what your polymer buyer actually needs
By PolyTro Team ·
Short answer: A COA (Certificate of Analysis) proves that a specific batch meets its specification, so it changes with every lot. An SDS (Safety Data Sheet) explains the hazards and safe handling of the product in general, so it changes only when the manufacturer revises it.
