Product type
Polyurethane resin is a versatile thermosetting polymer known for its durability and flexibility. It is created through the reaction of polyols and isocyanates, resulting in a material that can be formulated to achieve various hardness levels and properties. This resin is commonly used in applications requiring strong adhesives, coatings, and foams due to its excellent mechanical properties and resistance to chemicals and abrasion.
| Chemical composition | Polyols and isocyanates |
| Hardness range | Shore A 10 to Shore D 80 |
| Curing time | 1 to 24 hours depending on formulation |
| Temperature resistance | -40°C to 120°C |
| Density | 500 to 1500 kg/m³ |
When selecting polyurethane resin, consider the specific application requirements such as hardness, curing time, and temperature resistance. It is important to specify the desired chemical properties, including flexibility and adhesion strength, as well as any necessary certifications for safety and environmental compliance. Quantities should be determined based on project scale and usage rates.
