Influence of Talc in Polypropylene on Total Fluorine Measurements Used as an Indicator of Per- and Polyfluoroalkyl Substances (PFAS).

ABSTRACT:

Background

Increasing restrictions for chemicals of concern in plastic packaging materials have created an urgent need to accurately detect and quantify these chemicals. Total fluorine measurements have been utilized to screen for highly scrutinized per- and polyfluorinated substances (PFAS) in food packaging materials. Inorganic contributions to the total fluorine signal can result in false positive signals exceeding regulatory limits.

Objective

The purpose of this study is to develop a method for determining the contribution of talc inorganic filler to the total fluorine signal.

Method

The influence of talc on total fluorine measurements of plastics was evaluated by compounding talc with virgin polypropylene (PP) and then measuring the total fluorine concentration u
