Hot melts are a popular type of adhesive because they include such a diverse selection of products. Polyamides are one such example that offer superior bond strength, and Power Adhesives is one brand that makes a great collection of these adhesives. Our experts review these adhesives as a whole as well as highlight a few polyamide-based hot melt adhesives from Power Adhesives that may be suitable for your application.
What Are Polyamide Adhesives?
Polyamide adhesives are a type of hot melt known for their high bonding performance and durability in challenging environments. Along with having great tensile strength, they have a high resistance to heat, low temperatures, chemicals, and impact, so they are usable in harsh bonding environments where other hot melts may fail.
Because of their combination of strength and flexibility, they are a great fit for many industrial applications. Polyamides are commonly used with electronics, woodworking, textiles, and automotive assembly.
Benefits
Some of the most notable benefits of polyamides include:
- Compatibility with various substrates
- Excellent bond strength
- High heat resistance
- Chemical resistance
- Great durability
- Flexibility
All of these great qualities can come at a price. Some polyamides are more expensive than other types of hot melt adhesives and can have shorter shelf lives.
