Chemical Properties

Colorless, odorless oily liquid. Insoluble in water, soluble in most organic solvents. Compatible with a variety of cellulose, vinyl resins, chlorinated rubber, etc. Partially compatible with cellulose acetate and butyl acetate.


The product is a non-toxic, tasteless and safe plasticizer with excellent heat resistance, cold resistance, light resistance and water resistance. Suitable for food packaging, children's toys, medical products and other fields. Approved by the U.S. F.D.A. for meat food packaging materials and toys. Due to the excellent performance of this product, it is widely used in the packaging of fresh meat and its products, dairy product packaging, PVC medical products, chewing gum, etc. After plasticized by this product, the resin exhibits good transparency and low-temperature flexural properties, and has low volatility and extraction rate in different media. It is thermally stable during sealing and does not change color. It is used for non-toxic PVC granulation, films, sheets, cellulose coatings and other products; it can be used as a plasticizer for polyvinyl chloride, cellulose resin and synthetic rubber; it can also be used as a stabilizer for polyvinylidene chloride.
