What is Polyurethane PUR Hot Melt?
Reactive polyurethane, referred as PUR, is utilized in manufacturing of hot melt adhesive. Due to its superior strength, water and heat resistance, PUR is increasingly popular in variety of applications, specifically edge-banding, profile wrapping and laminaition, in manufacturing of woodworking furnitures.
Unlike traditional and economical EVA, and Polyolefin (APAO) materials, Polyurethane reacts with moisture in the air, gradually forms irreversable bond, in a "cross-linking" chemical process. The bonding continues to strengthen, typically within 48 hours. Once the PUR is completely cured, the bonding is permanet, and would not re-melt in the heat. This irreversible reaction guarantee its resistance against water and heat. In addtion, PUR requires less glue usage, to achieve good bonding, thus offers good finish with minimal visible glue-line.
