What documents help confirm the processing-aid effect of PPA Masterbatch?

PPA review usually starts with available TDS, SDS/MSDS, COA and the resin or extrusion condition you want to improve. Processing-aid effect should be reviewed by grade, resin and line condition before reliance. Document availability and suitability depend on exact product grade, application, destination and manual review. One document should not be treated as full-series compliance.
