Frequently Asked Questions

ASTM D1239 determines extractable components from plastic films using solvent extraction. It helps evaluate chemical residues, additives, and contaminants that may affect performance, safety, or compatibility in various applications.

Key parameters include solvent type, extraction time, temperature, and sample thickness. Controlled conditions ensure consistent removal of extractable substances from plastic films for accurate analysis.

The test measures amount of extractable material, typically reported as percentage or mass. Results indicate presence of additives, plasticizers, or impurities within the film.

ASTM D1239 is used for plastic films such as polyethylene, polypropylene, and other polymer films used in packaging, medical, and industrial applications.

ASTM D1239 depends on solvent selection and extraction conditions. Results may vary with method parameters and may not represent all possible extractable substances under different service environments.
