Performance characteristics
High chemical activity: The molecular structure contains active double bonds at the α and β positions, which can react with compounds containing active hydrogen such as olefins, hydrogen, nitriles, thiols, amines, ammonia, etc. by addition and amidation. It can participate in a variety of chemical reactions and synthesize compounds with different properties.
Good compatibility: It has good compatibility with a variety of polymer materials such as polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polystyrene, polymethyl methacrylate, etc., and can be evenly dispersed in these polymers to synergistically improve the properties of polymers.
High plasticizing efficiency: When used as a plasticizer, it can effectively reduce the glass transition temperature of the polymer, increase the flexibility and mobility of the polymer molecular chain, make the product have better softness, elasticity and cold resistance, and still maintain good physical properties at lower temperatures.
Low volatility: The molecular structure is relatively stable, the volatility is low at room temperature, the durability in the polymer is good, and the plasticizing effect can be maintained for a long time, reducing the performance degradation and environmental pollution caused by volatilization.
Strong stability: It has good light stability and thermal stability. During processing and use, it can resist the influence of factors such as light and heat, and is not easy to decompose or discolor, which can ensure the long-term performance of the product.
High flash point and not easy to self-polymerize: The flash point is high, and it is not easy to cause combustion or explosion due to open flames or high temperatures. The storage and use process is relatively safe. And it is extremely difficult to self-polymerize, which is convenient for long-term storage and long-distance transportation.
Mild odor: It will not produce pungent or unpleasant odors, and has little impact on the respiratory tract and working environment of operators during use.
Application field
Synthetic resin: It is one of the important raw materials for synthetic resins. It can be copolymerized with monomers such as vinyl chloride, (methyl) acrylate, styrene, and vinyl acetate to produce resins with internal plasticization. These resins have good flexibility, water resistance and weather resistance, and are widely used in plastics, rubber, coatings and other fields.
Coatings: Used in coatings, it can improve the flexibility, gloss and adhesion of coatings. Copolymers with vinyl acetate can be used as coatings. The paint film formed has good elasticity and weather resistance, which can effectively prevent the coating from cracking and falling off, and extend the service life of the coating.
Petroleum industry: It can be used as a lubricant, dispersant, etc. As a lubricant, it can reduce the friction coefficient between equipment, reduce wear, and improve the operating efficiency and service life of equipment; as a dispersant, it can evenly disperse impurities and additives in petroleum, prevent precipitation and agglomeration, and ensure the quality and performance of petroleum products.
Fabric: As an impregnating agent for fabrics, it gives fabrics a soft and smooth feel, while also improving the waterproof and anti-fouling properties of fabrics, making fabrics more durable and easy to care for.
Papermaking industry: Used as an impregnating agent and lubricant in the papermaking industry, it can improve the flexibility, strength and gloss of paper, and improve the printing adaptability and writing performance of paper.
Other fields: It can also be used as a gelation promoter, adhesive, gas chromatography stationary liquid, preservative additive, insecticide, fungicide, synthetic photosensitive latex, and surfactant, etc., and plays an important role in the fields of chemical industry, medicine, pesticides, etc.
Applications
Copolymerization: Copolymerization with other monomers is one of the main applications of diisooctyl maleate. By adjusting the type, proportion and reaction conditions of the copolymer monomers, polymers with different properties and uses can be synthesized. For example, when copolymerizing with vinyl chloride, the amount of diisooctyl maleate added can be controlled as needed to obtain polyvinyl chloride copolymers with different softness and mechanical properties.
As an additive: It can be directly added to various products as an additive to improve their performance. In coatings, it can be used as an additive for plasticizers and solvents to improve the performance of coatings; in plastics, it can be used as an internal plasticizer to enhance the flexibility and processing properties of plastics; in adhesives, it can be used as a plasticizer and viscosity regulator to improve the viscosity and flexibility of adhesives.
