PET PTFE Filter Cartridge 1. PTFE membrane is a microporous surface-filtration layer that can be laminated to polyester PET spunbond filter media. 2. The membrane is bonded to the PET substrate through a thermal lamination process. It supports surface dust capture and improved dust release during pulse-jet cleaning. 3. The fine microporous membrane can capture small dust particles while maintaining airflow. Filtration efficiency must be confirmed by the relevant test report and applicable test standard. 4. Polyester filter media offers good mechanical strength and can be selected for suitable industrial dust applications. Chemical compatibility must be confirmed according to the actual gas composition, temperature and chemical concentration.
