PUR hot melt adhesive, also known as polyurethane reactive hot melt adhesive, is a high-performance adhesive used for bonding a wide range of industrial materials. It combines the fast processing characteristics of hot melt adhesives with the durable bonding performance of polyurethane.
Unlike conventional hot melt adhesives, PUR hot melt adhesive continues to react with moisture after application and gradually forms a crosslinked structure. This post-curing process gives the adhesive excellent resistance to heat, moisture, and environmental conditions.
PUR hot melt adhesives are widely selected for applications requiring durable and reliable bonding.
Typical properties include:
The actual performance depends on the PUR grade, substrate, coating weight, processing conditions, and curing environment.
PUR hot melt adhesive is widely used in industrial lamination and assembly applications, including:
PUR hot melt adhesive is normally heated until it reaches its suitable processing temperature and then applied to one of the bonding surfaces.
The materials are subsequently laminated under controlled pressure. After bonding, the adhesive reacts with moisture in the environment and gradually cures, increasing the final bond strength.
Processing parameters such as melting temperature, coating weight, open time, pressure, bonding speed, and curing conditions should be selected according to the adhesive grade and application.
There is no single PUR hot melt adhesive suitable for every application. The right grade should be selected according to the substrates, production equipment, processing temperature, required open time, and final performance requirements.
Tianyang New Materials provides PUR hot melt adhesive solutions for automotive, textile, footwear, and other industrial bonding applications, with technical support based on individual customer requirements.
