Product Uses
Production of Polyurethane Materials: It is an important raw material for the production of polyurethane, widely used in the manufacture of polyurethane foams, elastomers, coatings, adhesives, etc. In the production of polyurethane foams, it reacts with polyols to form foam materials with different properties, which are used in the fields of thermal insulation, sound insulation, and cushioning. When used in elastomers, it can be used to manufacture rubber products with high elasticity, wear resistance, and aging resistance. When used in coatings and adhesives, it can provide good adhesion, chemical resistance, and mechanical properties.
Other Fields: It can also be used in the synthesis of some special materials. For example, it is used as a cross - linking agent in the production of some high - performance fibers to improve the strength and heat resistance of the fibers.
Packaging and Storage
Packaging: It is usually packaged in galvanized iron drums or steel drums, with a net weight of generally 250 kg per drum. There are also IBC tote - bin packages to meet the needs of different users.
Storage: It should be stored in a cool, dry, and well - ventilated warehouse, away from fire and heat sources. Avoid contact with water, alcohols, amines, and other substances, because MDI will react with these substances. The storage temperature is generally controlled at 5 - 25ºC to prevent the product from solidifying or deteriorating.
Safety Information
4,4'-Methylenebis(phenyl isocyanate) has a strong irritating effect on the skin, eyes, and respiratory tract. Inhalation or contact with its vapor or dust may cause allergic reactions, respiratory inflammation, and even pulmonary edema and other health problems. During use, appropriate protective equipment such as safety glasses, gloves, and respirators must be worn.
This substance is flammable and has a risk of combustion and explosion when exposed to open fire, high heat, or in contact with oxidants. Therefore, corresponding fire - fighting equipment should be equipped in the storage and use places, and fireworks are strictly prohibited. At the same time, its leakage into the environment should be avoided, because it may cause pollution to water bodies and soil.
