PUR has a highly flexible and strong adhesion, and suitable for a wide range of climates. With that extraordinary feature, PUR adhesive has become standard adhesive for hard-to-find materials.PUR adhesive, also called Polyurethane Reactive (PUR) Hot Melt Glues, is 100% solid content, isocyanate (NCO) capped adhesive. PUR will contact the moisture in the air, and allow it to form stronger bonds after the curing process is completed.
What is the reaction process of PUR Adhesive?
It is truly environment-friendly, and non-toxic adhesive.Therefore, the long drying tunnel is unnecessary when using PUR.As the solvent-free adhesive, PUR will not volatilize and emissions any solvent during the whole compound process.
Is PUR Adhesive an environment-friendly adhesive?
With the awareness of environmental protection, many governments improve the regulations of environmental inspection. Since 2010, solvent-free laminating technology in Europe and the American market has occupied an important place; also the demand for PUR is also increasing every year.
Is PUR Adhesive easy to transport?
YES.Instead of dangerous goods, it can be transported as general cargo. This means that the clients can place the order in a small amount with Container Freight Station(CFS).Comparing with another solvent adhesive, PUR has no explosion, fire, or other safety concerns.
Is PUR Adhesive high production efficiency?
When it comes to laminate the substrate in the same square, the consumption of PUR is lower than the solvent adhesive.The speed for Solvent-free composite machine production is ranged from 20 ~ 30M/min or faster up to 30~40M/min, in which the efficiency is double than dryer composite machine.
Application Of PUR Adhesive
Compared with acrylic adhesive, polyurethane (also called PU) adhesive provides extremely strong adhesion, isolation, and flexibility. The applications of PUR include Medical Products, Military Supplies, Various Films Lamination, Outdoor Functional Apparel, Electronic, Car Assembly, Woodworking Lamination, Biomedical Material Adhesive, and Fabric Lamination Adhesive.
