Polyamide hot melt adhesives are the adhesive of choice when standard EVA hot melts cannot meet the demands of the application. Offering outstanding heat resistance, excellent adhesion to metals and engineering plastics, and exceptional resistance to oils and chemicals, they are widely used across automotive, electronics, filtration, aerospace and industrial manufacturing. This guide explains where polyamide adhesives are used, why they’re chosen, and how to select the right grade for your application.
For many manufacturing applications, a standard EVA hot melt adhesive provides an excellent balance of performance and cost. However, when operating conditions become more demanding, manufacturers often turn to polyamide hot melt adhesives for their superior strength, heat resistance and long-term durability.
Polyamide hot melt adhesives are engineered for applications where reliability is critical. They are widely used across the automotive, electronics, filtration, aerospace and industrial manufacturing sectors because they continue to perform in environments where conventional hot melt adhesives may not.
At Kenyon Group, we supply a comprehensive range of polyamide hot melt adhesives, backed by extensive UK stock holdings, resilient supply chains and decades of technical expertise to help customers select the right adhesive for every application.
What Are Polyamide Hot Melt Adhesives?
Polyamide hot melt adhesives are high-performance thermoplastic adhesives designed for demanding industrial applications.
Unlike standard EVA hot melts, polyamide adhesives offer significantly improved resistance to:
- High temperatures
- Oils and greases
- Chemicals
- Mechanical impact
- Long-term environmental exposure
Although they typically command a higher purchase price than EVA adhesives, they frequently reduce overall manufacturing costs by delivering stronger, more durable bonds and reducing product failures.
When performance matters more than purchase price, polyamide is often the preferred solution.
Why Choose Polyamide Instead of EVA?
While EVA adhesives remain the workhorse of many packaging and assembly operations, polyamide adhesives are selected where higher performance is required.
Key Advantages
- Excellent heat resistance, typically up to 120°C to 150°C depending on grade
- Outstanding adhesion to metals
- Excellent oil and grease resistance
- Superior chemical resistance
- High flexibility without sacrificing bond strength
- Excellent impact resistance
- Fast setting speeds
- Reliable performance at low temperatures
- Long-lasting, durable bonds
These characteristics make polyamide adhesives ideal for demanding industrial environments where reliability is essential.
