Polyolefin hot melts are a unique combination of base resins and tackifiers.  This hot melt technology provides superior adhesion to polypropylene, a good barrier against moisture and water vapor, and excellent chemical resistance against polar solvents and solutions including acids, bases, and alcohols. 

  When compared with EVA and polyamide hot melt adhesives, polyolefins offer extended open times for positioning of parts.
 
  In the appliance industry, the use of polyolefins is expected to continue growing based on their ability to resist moisture and chemicals.   These adhesives offer new solutions for appliance makers in difficult-to-bond plastics applications such as bonding plastic hoses to inlets or bonding felt to dryer drums.
