Functions Comparison

Filter adhesives are often used to fabricate numerous filter components, to assemble the filter media itself, to bond the filter media into a frame or end cap or install the gasket and the main functions of each filter adhesive are as follows.

  • PU Adhesive
    Frame Molding. PU adhesives are often used to be molded to form PU air filter frames to replace the traditional metal end caps. It can be used as the air filter frames of both heavy trucks and cars as below.

  • Hot Melt Glue
    • Stabilization. The glue is often used to 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.
    • Spiral Warp Bonding. The glue is often applied to filter media or the outer support for spiral wrap bonding to stabilize the media or the filter during use.
    • Pleating. Radial pleating is when the filter media is wrapped into a cylindrical form. The glue is often used to bond the two ends of the cylindrical form together to stabilize the media during use.
    • Edge Bonding. The glue is often used to bond the filter media to the filter edge. It is commonly used in cardboard edge for HVAC filters.
    The hot melt glue is used to stabilize the middle line of the air filter.

    For air filters

    The hot melt glue is applied to the filter media for spiral wrap bonding.

    For air filters
