Complete Guide to Hot Melt Adhesives for Filter Assembly and Manufacturing

Effective filtration is becoming increasingly important in today's world. Whether it's the air inside your house, the drinking water in an urban metropolis or the fuel in a heavy-duty vehicle - filters are being asked to do more. In turn, filter manufacturers turn to Hotmelt.com when they need to accomplish more with their filter adhesives.  

Air filters in vehicles and buildings are high-performance products. They ensure a constant supply of fresh and clean air. Filters are very diverse and are frequently composed of different materials. Powerful hot melt adhesives for the manufacture of filters are not only characterized by a broad range of adhesion to the different materials but also facilitate superior products and efficient manufacturing processes. 

How are hot melt adhesives used in filter assembly?

Hot melt or water-based adhesives are used in the final stages of air, oil, water and HVAC filter manufacturing. They laminate multiple layers of media together, improving the filter's efficiency, filter adhesives are selected based on the following criteria: 

  • Substrate type
  • Fluid being filtered (hot air, fuels, lubricants, etc.)
  • Service temperature range
  • Adhesive application method

In the air filter manufacturing industry, there are many applications where hot melt adhesives are used. Hot melt adhesives are resistant to high and low temperatures and offer fast set times and so they are widely used in the manufacture of the air filters. 

Hot melt adhesives with fast set times are often the best choice when manufacturing air filters; because of the fast-running filter machines. Hot melt seals the filter frames, laminates the filter media and carefully closes the separators. 

EVA Hot Melt and APAO based hot melt adhesives that are flexible in cold temperatures, are good options for this application, these adhesives show excellent bond strength and machining characteristics. Check out our overview and Guide to (EVA) Ethylene-Vinyl Acetate Adhesives.

Polyamide based and polyester-based (PET) hot melts adhesives are also used for air filters in industrial or car ventilation systems that have to withstand high temperatures. These hot melts are highly chemical and heat resistant - and offer stronger adhesion to paper and non-woven fabrics. Depending on the application, hot melt dotting, bead, roll coating or spray application can be used.
