Cast Polyurethane

Cast polyurethane is similar to injection molding. CPU is a viscous liquid before processing, so it is called "liquid rubber". Polyurethane prepolymer refers to a reactive intermediate containing carbamate groups in the skeleton obtained from the reaction of polyisocyanate and polyol. The product can be used as an intermediate in the production of various polyurethane elastomer products. It is widely used in the fields of biomedicine and industry, and is suitable for desertification control, slope ecological protection, and soil erosion prevention and control. The so-called elastomer refers to a polymer material with glass transition temperature lower than room temperature, elongation at break > 50%, and better recovery after external force is removed. The polymer material whose glass transition temperature is higher than room temperature is called plastic. Among elastomers, those with higher elongation at break (>200%), smaller 100% modulus stress, and better elasticity can be called rubber. Therefore, elastomers are a wider class of polymer materials than rubber.

Cast polyurethane prepolymer, as the name implies, "casting type" refers to a chemical processing method in which the material system of the product is liquid before molding, which can be poured, reacted and solidified to directly form the product. In principle, the material system does not contain volatile liquids. Compared with metal materials, its characteristics are: 1. Light weight; 2. Low noise; 3. Wear resistance; 4. Low processing cost; 5. Strong corrosion resistance. Compared with plastic, it is characterized by: 1. Not brittle; 2. Elastic memory; 3. Good wear resistance. Compared with rubber, its characteristics are: 1. More excellent wear resistance; 2. More resistant to cutting and tearing; 3. Higher carrying capacity; 4. Can be transparent or translucent; 5. Better chemical resistance and weather resistance; 6. Wider range of hardness; 7. Various processing methods, lower mold and processing costs; 8. More environmentally friendly, healthier and more energy efficient.

Cast Polyurethane has excellent comprehensive properties, so it is widely used in various fields. Polyurethane rubber rollers, rubber wheels, sieve plates, seals, etc. are still important products of cast polyurethane elastomers. The quality of CPU products is improving, the varieties are increasing, and the application fields are expanding. This is the development trend. Polyurethane elastomers such as flame-retardant, heat-resistant, damping, and low-friction have broad market space and development prospects, and have attracted great attention from the industry.
