2 Product description Triacetin is a clear, colourless acetate ester used for example in the manufacture of cigarette filters. Triacetin is also used for plasticising NBR and cellulose derivatives. Storage stability Under suitable conditions, Triacetin can be stored for one year. Triacetin can be stored in a stainless steel tank (V4A;

material no. 1.4571 [AISI 316Ti]). Solubility Triacetin is readily soluble in aromatic hydrocarbons and most organic solvents. It is insoluble in aliphatic hydrocarbons, mineral oils, and vegetable and animal oils. Solubility in water is low. Packaging Road tankers

230 kg drums General properties The major features of Triacetin are : ? excellent suitability for the solidification of acetyl cellulose fibres for the manufacture of cigarette filters ? very good dissolving power for a number of organic substances ? good plasticising effect for various plastics such as celluloseacetates or celluloseacetobutyrates ? good plasticising effect for cellulose-based paints ? good compatibility with natural and synthetic rubber ? good light resistance Applications Triacetin is used for the solidification of acetyl cellulose fibres in the manufacture of cigarette filters. The water content must be kept constant to achieve constant solidification. Triacetin is also used as a support for flavourings and essences in the food industry and as a plasticiser for chewing gum. In technical applications, Triacetin is used for example as a core sand binder in the metal foundry sector. Another application is inks and printing inks. Triacetin is used as a highly- effective plasticiser for cellulose-based plastics. The above formulation is intended solely as a guide for our business partners and others interested in our products.
