Top 5 Uses of Polyurethane Adhesives and How They Improve Product Durability

Polyurethane products have become an indispensable part of every individual’s life what with a huge number of such products present around you in every part of your house. Polyurethane is a revolutionary material that has superlative attributes like high impact strength, toughness, machinability, top resistance to fatigue and thermal aging and these attributes make it a top favorite in several industrial applications.  

Five top areas where polyurethane adhesives are a must have include areas like construction, footwear, woodworking, automotive and packaging. What are their attributes that help to improve product durability in these industrial spheres? 

  • High flexibility 

  • Top-rated bonding strength 

  • Fatigue resistance 

  • Resistance to environmental factors 

  • Lightweight 

Following brief explains how these attributes go a long way in improving product durability in the above mentioned five areas. 

Let’s start with packaging.  

Packaging: PU adhesives bond easily with varied packaging substances like foil, paper, and plastic. They are resistant to oil and water and this factor is very vital to enhance product integrity. Leakage and damage is prevented and the product remains packed in the original condition for as long as needed. Regularity requirements are also fulfilled by polyurethane adhesives and this makes it a highly useful item in the packaging industry.  

Construction: Polyurethane adhesives help to bond structural items such as panels of walls, floor insulation, door and window installations. Weather and fatigue resistance, a quality attributed to PU adhesives ensures product durability in applications that come under the construction industry. Some other qualities that make it a hot material in the construction industry include its insulation attributes, strength to weight ratio, versatility and durability. Structures remain long-lasting and are not affected by moisture and fluctuations in temperature. 

Woodworking: Moisture resistance, an attribute that is vital for enhancing the life of furniture items is offered by PU adhesives. It is used as a coating layer that helps to protect wooden furniture from dampness and moisture. Alongside, its capacity to bond strongly with varied surfaces helps to enhance durability of joints and lamination that is so needed in woodworking. Several sofa cores and cushions for bay windows go for PU adhesives. 

Automotive: The high bonding capacity of polyurethane adhesives makes it a favorite in the automotive industry. It is widely used in the assembly of varied vehicle components ranging from body panels and windows to the interiors of the vehicle. PU adhesives have the capacity to bond materials that are dissimilar and this helps in production of automotive that gives better performance and has higher fuel efficiency. 

Footwear: Tough bonding of soles is essential for enhancing durability of your footwear especially your athletic footwear. Polyurethane adhesives are highly resistant to abrasion and coupled with their flexibility; they offer support, comfort and long life to your wide ranging footwear. Its usage in the midsole enables flexibility of foot movement and since it doesn’t melt, helps to wash your footwear in the washing machine. Your footwear lasts for long periods in spite of continuous wear and tear. 

On a summarizing note 

Polyurethane adhesive is a dependable and versatile substance that improves product durability in whichever application it is used. No wonder, it is a top favorite among the manufacturers!
