GB/T 44825-2024
ActiveTest method for determination of total fluorine in biodegradable materials and plastics
生物基材料与降解塑料中总氟含量测定试验方法
Application Summary AI generated
This standard specifies a test method for determining the total fluorine content in biodegradable materials and plastics, including biobased polymers and compostable plastics. It is applied in quality control and environmental testing within the plastics industry, particularly for verifying compliance with fluorine-free or low-fluorine requirements in packaging, agricultural films, and disposable products. The method supports regulatory assessments and material certification by detecting fluorine from additives or processing residues.
