Product Traits & Physical Properties
DOP (Dioctyl Phthalate) is a colorless transparent oily liquid at normal temperature, with a slight special odor. It boasts outstanding compatibility with most synthetic resins and rubber materials. This chemical substance is insoluble in water, and easily soluble in organic solvents such as ethanol, ether and mineral oil. It features low volatility, excellent cold resistance, heat resistance and electrical insulation performance. Stable under conventional storage and transportation environments, the product meets international industrial production and export standards, and holds complete REACH certification qualifications.
Product Applications
DOP serves as a primary plasticizer applied extensively in the plastic and polymer processing industry. It can effectively improve the flexibility, ductility and processability of PVC resin, synthetic rubber, cellulose resin and other materials. Common application scenarios include PVC soft products such as plastic films, hoses, wires and cables insulation, artificial leather, plastic toys and architectural decoration materials.
In addition, Dioctyl Phthalate can be used as a lubricant, softener and dispersant in rubber, coating and adhesive industries, providing stable product performance for downstream industrial manufacturing. Complete document support including MSDS download is available for global commercial trading and safety assessment.
