This product is a colorless or light yellow transparent oily liquid. It is odorless, highly stable, not easy to volatilize, and has good plasticizing flame retardancy, oil resistance, electrical insulation, and easy processing. It is insoluble in water, but soluble in organic solvents such as benzene, alcohols, ethers, vegetable oils, and mineral oils. This product is an important plasticizer for vinyl resins and nitrocellulose. It can increase the flexibility of the paint film when used in paints. It has excellent compatibility and is a flame retardant for synthetic rubber, polyvinyl chloride, polyester, polyolefin, and soft polyurethane foam plastics. It can also be used in polyurethane electronic potting glue. This product can give polymers good wear resistance, weather resistance, mildew resistance, radiation resistance, and electrical properties. This product is improved using a new process and is an environmentally friendly product. There is basically no three wastes generated during the production process, and the product is low in toxicity.
