Main features of PUR
1. High bonding strength
PUR has extremely strong bonding ability and is suitable for a variety of materials such as metal, plastic, wood, glass, etc. It can maintain stable adhesion even in extreme environments such as vibration and impact.
2. Fast curing
Curing through moisture, no high-temperature baking is required, energy-saving and efficient, suitable for automated production lines.
3. Excellent physical properties
- Wear and oil resistance: Suitable for high wear environments such as automotive parts, conveyor belts, etc.
- High and low temperature resistance: Can maintain performance in the range of -50℃ to +90℃, suitable for extreme climates.
- Chemical corrosion resistance: Good resistance to oils, solvents, acids and alkalis.
4. Environmental protection
Does not contain organic solvents, solid content 100%, in line with green environmental protection standards.
5. Good processing performance
Easy to automate, high production efficiency, suitable for large-scale manufacturing.
Specific applications of PUR
1. Automotive industry
- Used to manufacture interior and exterior trims such as bumpers, dashboards, seats, steering wheels, etc., with strong impact resistance and weather resistance.
- Lightweight design, can replace traditional metal parts and reduce the weight of the whole vehicle.
2. Construction industry
- As waterproof, heat-insulating and sound-insulating materials, used for roof, wall, pipe insulation, etc.
- Used for sealants and adhesives to improve the durability of buildings.
3. Electronics and home appliances
- Used for wire and cable sheaths and electrical insulation layers, with good electrical insulation.
- Insulation materials for refrigerators and air conditioners.
4. Packaging and binding
- Used for wireless binding of books, with strong bonding and folding resistance.
- Composite bonding of food packaging, safe and non-toxic.
5. Shoe materials and furniture
- Soles and insoles, wear-resistant and comfortable.
- Foam filling for sofas and mattresses, providing good support.
6. Medical and Aerospace
- Used in medical materials such as artificial blood vessels and catheters, with good biocompatibility.
- Aircraft parts, reducing weight and improving strength.
