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.

4. Storage conditions of raw materials

Storage requirements	Raw materials	Time	Storage condition	Shelf life
	HJ33M-A	May 1-October 1 (spring and summer)	Below 30 ℃, keep away from light and dry, and it is recommended to store it in cold storage	6 months after receipt > 30 ℃ storage time < 1 month
	HJ33M-A	October 1-May 1 (autumn and winter)	Under 30 ℃, keep away from light and dry, without other special requirements	6 months after receipt of the goods
	HJ33M-B	Year-round	Store at room temperature, away from light and dry	2 years after receipt of goods
	HJ33M-C	Year-round	Store at room temperature, away from light and dry	2 years after receipt of goods
	Catalyst	Year-round	Store at room temperature, away from light and dry	2 years after receipt of goods
