ActiveOptical functional films—Polyethylene terephthalate（PET) film—Determination of extraction rate
光学功能薄膜 聚对苯二甲酸乙二醇酯（PET）薄膜 萃取率测定方法
Application Summary AI generated
This standard specifies a method for determining the extraction rate of polyethylene terephthalate (PET) films used in optical functional applications, such as display screens and lighting components. It is applied in quality control and material testing within the electronics and optical film manufacturing industries to assess the purity and stability of PET films by measuring the amount of low-molecular-weight substances that can be extracted under defined solvent conditions. The test ensures that the film meets performance and reliability requirements for use in sensitive optical environments.
