Application:
1. The primary product of this product is widely used in polyurethane coatings. In addition, it is also used in waterproof materials, sealing materials, pottery materials, etc.; polyurethane foam made of this product is used as parts for thermal insulation (cold), building materials, vehicles, and ships. ; Refined products can be made into car bumpers, buffers, synthetic leather, non-plastic polyurethane, polyurethane elastic fiber, non-plastic elastic fiber, film, adhesive, etc.
2.MDI is the general name for 4,4’diphenylmethane diisocyanate (pure MDI), a mixture containing a certain proportion of pure MDI and polyphenylpolymethylene polyisocyanate (polymerized MDI), and modified products of pure MDI and polymerized MDI. , is the most important raw material for the production of polyurethane. A small amount of MDI is used in other aspects besides polyurethane. Polyurethane has the elasticity of rubber, the strength and excellent processing properties of plastic, especially in terms of heat insulation, sound insulation, wear resistance, oil resistance, elasticity, etc. It has advantages that other synthetic materials cannot match. The sixth largest plastic after ethylene, polypropylene, polystyrene and ABS (now surpassing ABS to become the fifth largest plastic), it has been widely used in national defense, aerospace, light industry, chemical industry, petroleum, textile, transportation, automobile, medical, etc. fields, becoming an indispensable emerging material for economic development and people’s lives.
MDI and TDI are substitutes for each other and are both raw materials for the production of polyurethane. The price of MDI is slightly lower and its toxicity is lower than that of TDI. However, when producing foam, the density is higher than that of the TDI system. The moldability of polyurethane products formed by MDI is relatively good.

Application
Functional solvents are versatile substances that find application in various industries and processes. Here are some common applications of functional solvents:
01. Industrial Cleaning
Functional solvents are widely used in industrial cleaning applications, especially for removing oils, greases, dirt, and other contaminants from machinery, equipment, and parts. They help dissolve and remove stubborn residues, ensuring efficient and effective cleaning.
02. Paints and Coatings
Functional solvents play a crucial role in the formulation of paints, varnishes, and coatings. They are used to dissolve and disperse the main ingredients, such as resins, pigments, and additives, creating a homogeneous mixture. They also control the viscosity, drying time, and application properties of the final coating.
03. Adhesives and Sealants
Functional solvents are utilized in the production of adhesives and sealants. They help dissolve or disperse the adhesive components, allowing for easy application and uniform coverage. Solvents can also contribute to the adhesive’s curing process by evaporating and facilitating bonding.
04. Pharmaceuticals and Personal Care Products
Functional solvents have applications in the pharmaceutical and personal care industries. They are used in the formulation of drugs, cosmetics, and other personal care products. Solvents help dissolve active ingredients, enhance stability, and ensure proper consistency and texture of the final product.
05. Printing Inks
Functional solvents are essential components in printing inks. Solvents help dissolve pigment particles, binders, and additives, making them suitable for various printing techniques. They contribute to ink viscosity, drying time, and print quality.
06. Chemical Reactions and Extractions
Functional solvents serve as reaction media or extraction agents in chemical processes. They facilitate the dissolution, reaction, or extraction of specific compounds, enabling purification, separation, or synthesis of desired products.
07. Electronics and Semiconductor
Functional solvents are used in the production, cleaning, and testing of electronic components and semiconductors. They aid in the removal of impurities, residues, and contaminants from surfaces, ensuring optimal performance and reliability.
08. Metal Cleaning and Degreasing
Functional solvents are employed for cleaning and degreasing metal surfaces, such as in automotive and industrial applications. They effectively dissolve oils, greases, and contaminants, preparing the surface for further treatment or coating.
09. Fragrance and Flavors
Functional solvents are utilized in fragrance and flavor industries. They help dissolve and carry fragrant or flavoring compounds, allowing them to be mixed, blended, and applied in various products such as perfumes, colognes, food, and beverages.
10. Energy Sector
Functional solvents are utilized in the energy sector for various purposes. One of the notable applications is in oil and gas production. Solvents are used in processes such as well stimulation, where they help dissolve and remove formation damage, improving the productivity of the well.
It’s important to note that the choice of functional solvent depends on the specific application requirements, including compatibility with materials, environmental considerations, health and safety concerns, and regulations. Each industry and application might have its own set of recommended solvents or solvent blends. Therefore, it’s best to consult experts or professionals in the specific field or industry to ensure proper solvent selection and usage.
