Do you know about Filter Media Substrate？

The filter media substrate is the foundational support material used in the production of filtration materials. It forms the core part of the filter media, determining its mechanical strength and durability while providing a carrier for additional functional filtering materials (such as coatings or functional fibers).

The performance of the filter media substrate directly impacts the final effectiveness of the filtration material, as reflected in the following aspects:

1. Filtration Efficiency: The porosity and structure of the substrate directly affect its ability to capture particles.
2. Mechanical Properties: Including tensile strength, pressure resistance, and wear resistance, which determine the lifespan and stability of the filter media during use.
3. Application Scenarios: Different substrates offer varying levels of temperature resistance and chemical corrosion resistance, making them suitable for various industrial or civilian environments.

Common filter media substrates include:

• Spunbond or meltblown nonwoven fabric: Widely used for air or liquid filtration.
• Glass fibers: High-temperature resistant and suitable for industrial applications, such as flue gas filtration.
• Metal mesh: Provides additional structural support, ideal for high-strength environments.
• Polymeric materials (e.g., polyester fibers): Chemically stable and widely used for water filtration or dust removal applications.
