Overview – What Are Polyamide Hot Melts (PA / Nylon)
Polyamide hot melts are thermoplastic adhesive systems produced from dimerized fatty acids, diamines and nylon-based polymers. They are known for high heat resistance, chemical durability, excellent adhesion to difficult substrates, and superior toughness compared to EVA or APAO hot melts.
PA hot melts are widely used in industrial assembly, electronics, automotive, filter manufacturing, textile, woodworking, and packaging applications.
Meaning & Definition
Polyamide hot melts (PA / Nylon) are solid adhesives at room temperature, melted and applied in molten form, and solidified upon cooling to create a fast-setting, strong adhesive bond.
They show high softening points (often 130–200°C), making them suitable for high-temperature environments.
