The Differences Between Hot Melt Polyamide Adhesives and Other Adhesives

When it comes to adhesives, hot melt polyamides adhesives (HMPAs) stand out with their impressive range of advantages. These high-performance adhesives offer exceptional properties that make them a top choice for various applications. 

Let's delve into the features that make HMPAs a go-to solution for bonding needs.

Exceptional Temperature Resistance: 

With remarkable thermal stability, HMPAs can withstand elevated temperatures of up to 170°C. This characteristic ensures reliable bonding even in demanding environments where heat is a factor.

Unmatched Chemical Resistance: 

HMPAs exhibit superior resistance to corrosion, acids, alkalis, oils, petroleum, gasoline, plasticizers, hydraulic fluids, and more. This makes them suitable for applications requiring resistance to harsh chemical substances.

Reliable Solvent Resistance: 

These adhesives offer exceptional resistance to solvents, including water, alcohol, and a wide range of solvents commonly encountered in industrial and commercial settings.

Versatile Bonding Capabilities: 

HMPAs excel at bonding non-polar substrates, including non-polar plastics like PP and PTFE, as well as weakly polar plastics such as PS and ABS. This versatility expands their application potential across various material types.

Thriving in Low Temperatures: 

With impressive low-temperature performance down to -40°C, HMPAs ensure reliable bonding even in cold environments, providing exceptional strength and durability.

User-Friendly Processing: 

HMPAs are known for their ease of processing, particularly through low-pressure molding techniques. This characteristic streamlines manufacturing processes, saving time and effort while maintaining adhesive performance.

PVC Plasticizer Compatibility: 

One notable advantage of HMPAs is their resistance to PVC plasticizers. This property ensures stable bonding when working with materials that contain plasticizers.

Sustainable and Green Strength: 

As environmentally conscious solutions, HMPAs are often made from renewable resources. This not only offers sustainable options for adhesive applications but also contributes to reducing the environmental footprint.

Controlled Open Time: 

HMPAs provide flexibility in application with a controllable open time ranging from less than 2 seconds up to 40 seconds, allowing for efficient bonding processes tailored to specific needs.

Wide Range of Adhesion: 

HMPAs offer broad adhesion capabilities, including bonding to porous substrates such as paper, wood, metal, plastic (including plasticized PVC), and permeable materials. This versatility opens up a multitude of possibilities for various industries.

Exceptional Strength: 

With high strength properties, HMPAs deliver reliable bonds that can withstand demanding applications. Boasting a tensile strength of 2000 psi (13.8 MPa), they ensure long-lasting and durable adhesion.
