We are committed to creating value for society, innovating science and technology, and bringing more choices of products and services to consumers around the world. The company has strong technical force, and has always adhered to people-oriented technological innovation.
Quazi MDI Three componment casting PU
1. Characteristics of MDI raw materials
The same raw materials can be produced with different hardness by adjusting the A/B/C component ratio, and the raw materials need not be replaced in the hardness switching process.Because MDI has excellent symmetry and two benzene rings in molecular structure, MDI products can endow products with better comprehensive physical properties. At the same time, because of chemical reaction factors, the product characteristics are also different from TDI.
(1) Higher resiliency
(2) Higher shrinkage rate
(3) Aging resistance and improved color stability
(4) Decreasd temperature resistance
2. MDI three-component feedstock belongs to semi-prepolymer, and the reaction rate of-0H is less than that of-NH2. In order to obtain better physical properties and production efficiency, catalyst is needed.
3. Environmental protection
The vapor pressure of MDI is much lower than that of TDI, and it has aromatic odor and little toxicity in the production process, so MDI is a new material that meets the needs of environmental protection.
