Hot melt adhesives are widely used in the manufacturing of filters due to their excellent bonding properties, quick set times, and resistance to various conditions. While the exact number of hot melt adhesives used can vary depending on the specific requirements of the filter, there are several common types that are frequently used in this industry.

1. Ethylene-vinyl Acetate (EVA)

EVA-based hot melt adhesives are commonly used due to their versatility, excellent adhesion, and good resistance to heat and chemicals. They are often used in automotive filters, air filters, and water filters.

2. Polyolefin

Polyolefin-based hot melt adhesives are known for their excellent heat resistance, making them suitable for applications that require high-temperature resistance. They are often used in oil filters and high-performance air filters.

3. Polyamide

Polyamide hot melt adhesives offer excellent resistance to a wide range of chemicals, oils, and solvents, making them ideal for use in fuel filters and other filters exposed to harsh conditions.

4. Polyester

Polyester hot melt adhesives are known for their strong adhesion and excellent resistance to heat and chemicals. They are often used in high-efficiency particulate air (HEPA) filters and other high-performance filters.

5. Pressure Sensitive Adhesives (PSA)

PSA hot melt adhesives remain tacky even after cooling, allowing for repositioning and adjustment during the assembly process. They are often used in air filters and other filters where flexibility is required.

Please note that the selection of the adhesive depends on the specific requirements of the filter, including the materials used, the operating conditions, and the required performance characteristics. Therefore, it's always important to work with an adhesive expert or supplier to select the right adhesive for your specific application.
