Foam-in-Place Gasketing and Sealing

Manufacturers in the automotive, electronics, construction and appliances markets often use gaskets to provide a tight seal between two surfaces to prevent leakage. These gaskets serve as a complete barrier and have gap-filling properties.

Rather than manually applying gaskets to seal two surfaces, manufacturers can use a foam-in-place gasketing and sealing system to automate the process.

What is Foam-in-Place Gasketing and Sealing?

Foam-in-place gasketing and sealing is an adhesive dispensing equipment system that works well in a range of applications. Some of these include:

  • Automotive: door handles, audio systems and filters
  • Electronics: dust sealing and cushioning applications
  • Construction: window and door and HVAC
  • Appliance: insulation assemblies and general purpose

What Benefits Does Foam-in-Place Gasketing and Sealing Offer?

Manufacturers reported that the foam-in-place gasketing and sealing system enabled them to:

  • Reduce direct labor costs by around 80% and indirect by upwards of 50%
  • Eliminate scrap and rework by about 50%
  • Reduce in-process inventory by as much as 35%
  • Reduce material costs by close to 25%
  • Eliminate warranty and field service by about 15%*

What Factors Need to Be Considered When Choosing a Foam-in-Place System?

Before choosing a foam-in-place system, you must consider the following:

  • Type of bond required
    • Sealing
    • Barrier
    • Gap-filling
    • Non-skid (high coefficient of friction)
  • Materials to be bonded
    • Helps determine the appropriate type of adhesive technology
  • Dispensing equipment
  • Automation selection and peripheral equipment

Types of Adhesive Technologies for Foam-in-Place Gasketing and Sealing:

Bostik offers a range of adhesive products designed specifically for foam-in-place gasketing and sealing systems. They include:

  • Hot melt thermoplastic sealers
  • Single-component polyurethanes
  • Silyl-modified polymers

While the technologies vary, all of Bostik’s foam-in-place adhesives enable the gasket to be built exactly in the place desired. As a result, there is no waste and lower cost in use. These adhesives also offer customized foam density and bead dimensions.
