Hot melt pressure sensitive adhesive

 

Our HMPSA adhesives provide exceptional performance and efficiency for industrial applications

From bonding diapers to aircraft interiors, our hot melt pressure sensitive adhesives are hugely popular systems for industrial manufacturing.

Hot melt pressure sensitive adhesives are a unique class of bonding materials used in a wide range of industrial applications and consumer products. While solid at room temperature, these adhesives melt readily, providing free-flowing liquids which can be dispensed to the target bonding site in a precisely-controlled manner. Upon cooling, hot melts solidify to rapidly form strong bonds between two substrates.

Not only do HMPSAs possess exceptional tack capabilities, they also enable significantly faster setup times than solvent-based, water-based and curable adhesive systems. 

The rapid and precise application of Bostik hot melts makes them a staple within high-speed manufacturing processes, such as automotive assembly.

At Bostik, we design our HMPSA systems to meet your specific performance requirements.  Where stickiness of an exposed adhesive is undesirable, for example with porous nonwovens, our hot melt systems can be tailored to possess lower tack as solids. Conversely, for applications like labelling, systems can be designed to display pressure sensitivity, allowing solid adhesive to form bonds with minimal force. Strength, tack and failure mode can all be adapted for the unique demands of your industry application. Our hot melts also come in a variety of physical forms, including granulates, pastilles, sticks, or molten bulk.

Smart Innovation

Our expertise in hot melt pressure sensitive adhesives has led to many smart innovations:

  • Food packaging: our HMPSA systems can be used for various forms of food packaging, from re-sealable meat and cheese packaging to yogurt lidding. More on flexible packaging solutions.
  • Baby diapers: we formulated a wetness indicator using specialized hot melt technology. This innovation is now adhered to the back sheets of approximately 80 billion diapers produced every year. More on our solutions for disposable hygiene.
  • Aerospace components: our economic and versatile hot melt web adhesives are frequently used for skin to core composite structures in airplanes and other airborne vehicles. Their excellent fire-retardancy and lack of VOC emissions exceed the stringent regulations of the aerospace industry. More on our solutions for aerospace.
