Filter Adhesive Uses, Applications and Technologies

In a recent blog, we discussed the future of the filtration market and what it means for filter manufacturers. These changes and challenges within the market include the fracking boom, automotive weight reduction, increased environmental regulations and water scarcity.

Now, let’s take a look at adhesives’ role in the filtration market, the applications, technologies and products that can help manufacturers meet these changes and challenges.

How Adhesives are Used in Filters:

Adhesives are used to construct the final assembly in air, oil, water and HVAC filters. They laminate multiple layers of media together, improving the filter’s efficiency. viavisolutions.com 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

Key Applications for Filter Adhesives:

Filter adhesives can be used in several applications including:

  • Pleating/Stabilization: Adhesives keep the pleats separated to ensure uniform flow of the fluid and maximize efficiency and capacity. Spiral beads of adhesives are applied to stabilize the media during use.
  • Frame Assembly/End Cap Bonding: Adhesives are used to bond the filter media to the frame assembly. This includes:
    • Metal or nylon end caps for oil, fuel and water filters
    • Plastic or metal frames for high efficiency air filters
    • Cardboard frame for HVAC filters
  • Gasketing: Adhesives are used to bond rubber gaskets to the end caps, or a foam-in-place adhesive can be the gasket itself. A recent blog discusses foam-in-place gasketing and sealing.
