PUR hot melt adhesive (Polyurethane Reactive), namely moisture curing reaction polyurethane hot melt adhesive, is a kind of adhesive industry has an important position. It is famous for its excellent adhesive strength, heat resistance, chemical corrosion resistance and aging resistance, and is widely used in packaging, wood processing, automobile, textile, electromechanical, aerospace and other national economic fields.
The main applications for PUR hotmelts include:
1. Automotive industry: Used for bonding automotive structures and components, such as windshield seals and lamp assembly.
2. Textiles and footwear: Used for fabric seam bonding and sole bonding, and has the advantages of water resistance, softness and comfort.
3. Wireless Book Binding: The rubber layer is flexible, improving the flatness of turning over and preventing the bookbinding from forming grooves or books closing suddenly.
4. Food packaging industry: can withstand the high and low temperature disinfection treatment of food hygiene regulations.
5. Woodworking and Furniture Industry: The glue layer has good water resistance and aging resistance, and does not pollute and corrode wood.
6. Electronics and electrical appliances: The adhesive layer is fast solidified, and the curing shrinkage rate is small, which is suitable for bonding precision components.
In addition,PUR hot melt adhesive also has good environmental protection performance, does not use solvents and harmful chemical substances, reduces the pollution to the environment and the harm to the health of staff. At the same time, it has high strength, flexibility and versatility, and can maintain tensile strength in a variety of environments, especially at high temperature, humidity or low temperature.
In the field of electronic products,The PUR hot melt adhesive also meets the development requirements of modern intelligent equipment due to its strong adhesiveness after curing, high strength and easy control of the thickness of the glue. It is widely used in bonding, sealing, stacking, connecting, insulating, electronic protection and assembly of products such as smart phones, tablets, and wearable electronic devices.
Overall,PUR hot melt adhesive because of its excellent comprehensive performance, has become an indispensable adhesive material in many industries.
