Tributyl Citrate(TBC) is the butyl ester of citric acid, a colorless oily liquid, soluble in most organic solvents. Besides, TBC is easily soluble in resin, and has low volatility, high plasticizing efficiency. So this ester is a non-toxic plasticizer that can be used as a plasticizer in non-toxic PVC granulation, food packaging. Furthermore, TBC plasticizer can increase the low temperature resistance, water resistance, and mildew resistance of the product. In addition, offered here at Integratechem, one of the leading and professional China manufacturers and suppliers. Furthermore, tributyl citrate factory produces it use citric acid and butyl alcohol.

4. Application & Advantages
Tributyl Citrate(TBC) is a colorless oily liquid, soluble in most organic solvents, has low volatility as well as high plasticizing efficiency, and is easily soluble in resin. Further more, tributyl citrate plasticizer can increase the low temperature resistance, water resistance, and mildew resistance of the product. So TBC is a non-toxic plasticizer that can be used as a plasticizer in non-toxic PVC granulation, food packaging, children’s toys, medical supplies, polyvinyl chloride, and vinyl chloride copolymer production. In addition, manufacturers and factories produce Acetyl Tributyl Citrate by acetylation of Tributyl Citrate(TBC).
