TCC's NatureFlexx 509 (Acetyl Tri-n-Butyl Citrate) plasticizer is a nontoxic, innocuous, tributyl ester that affords a wide range of benefits when used as a plasticizer in aqueous and solvent-based polymers. These polymers include acrylic, methacrylic, ethylcellulose, hydroxymethyl cellulose, nitro cellulose, vinyl acetate, vinyl chloride, vinylpyrrolidone vinylide chloride and urethane polymer formulations.

NatureFlexx 509 plasticizer is a colorless, transparent oily liquid that is soluble in most organic solvents. This low volatility compound is compatible with a wide variety of resins, and has a good plasticization effect. The product's resistance to cold temperatures and light exposure is similar to that of tributyl citrate, and water resistance is better.
