Introduction to Cast Polyurethane Elastomers
Cast polyurethane elastomers (PUs) are a versatile group of materials formed by the polymerization of polyols and isocyanates. They are known for their exceptional mechanical properties, flexibility, and resilience. The casting process allows for precise control over the material's properties, enabling tailored solutions for various applications. Cast PUs can be produced in a wide range of hardness levels and can be customized with additives to enhance specific characteristics, such as flame retardancy, UV stability, and abrasion resistance.
Key Properties:
- High tensile strength and elongation.
- Excellent abrasion resistance and tear strength.
- Good chemical resistance to oils, solvents, and fuels.
- Wide temperature range performance.
- Elasticity and flexibility, making them suitable for dynamic applications.
