Dioctyl Maleate, with the CAS number 2915 - 53 - 9, is a chemical compound widely recognized in the industrial field. It is an ester formed by the reaction of maleic acid and 2 - ethylhexanol. This product is typically presented as a clear, colorless to pale - yellow liquid.
Some of its key physical and chemical parameters are as follows: Molecular formula: C20H36O4; Molecular weight: approximately 340.5 g/mol; Density: around 0.94 g/cm³ at 20 °C; Boiling point: about 280 - 290 °C; Flash point: 138 °C (closed - cup). It is insoluble in water but soluble in most organic solvents such as ethanol, acetone, and benzene.
Dioctyl Maleate has a wide range of applications. In the polymer industry, it serves as a plasticizer. When added to polymers like polyvinyl chloride (PVC), it can enhance the flexibility, softness, and processability of the polymers. By reducing the glass - transition temperature of PVC, it makes the material more suitable for a variety of applications, from flexible tubing to soft toys.
It is also used in the production of adhesives and sealants. Dioctyl Maleate can improve the adhesion strength and flexibility of adhesives, making them better able to bond different materials together. In the coating industry, it can be used as a reactive diluent, which helps to reduce the viscosity of coatings while maintaining or even improving their performance.
When using Dioctyl Maleate, proper safety precautions should be taken. Always wear appropriate personal protective equipment, such as gloves and safety goggles, to prevent skin and eye contact. In a well - ventilated area, measure out the required amount of the product accurately. If it is being used as a plasticizer in PVC production, it should be mixed evenly with the PVC resin during the compounding process. The mixing temperature and time should be controlled according to the specific process requirements to ensure the uniform distribution of the plasticizer in the polymer matrix.
For use in adhesives or coatings, it should be added to the formulation at the appropriate stage of the production process. Stir well to ensure complete dissolution and homogeneous mixing. After use, the product should be stored in a cool, dry place, away from direct sunlight and sources of heat.
1. PVC Flooring Production: A flooring manufacturer incorporated Dioctyl Maleate as a plasticizer in their PVC flooring production. By adding an appropriate amount of Dioctyl Maleate, they were able to produce flooring with excellent flexibility and resilience. The flooring could be easily installed in various spaces, and it maintained its softness and durability even under heavy foot traffic. The product passed all the relevant quality and safety tests, meeting the high - end market demand.
2. Adhesive for Woodworking: A woodworking company used Dioctyl Maleate in their adhesive formulation. The resulting adhesive had significantly improved bonding strength and flexibility. It could bond different types of wood together firmly, even in environments with temperature and humidity variations. The furniture produced using this adhesive had a longer service life and better quality, which helped the company gain a competitive edge in the market.
