2,2,4-Trimethyl-1,3-pentanediol isobutyrate (Cat No.:R070940) is a branched diol ester with the molecular formula C12H24O3. It is a clear, low-viscosity liquid commonly used as a non-phthalate plasticizer in flexible PVC and other polymer formulations. TXIB imparts softness, low-temperature flexibility, and excellent workability to coatings, adhesives, sealants, and elastomers. Its low volatility and minimal contribution to film tackiness make it particularly valuable in water-based systems. Additionally, TXIB enhances flow and leveling properties, making it ideal for applications such as wall coverings, flooring, inks, and automotive interiors where performance and safety are critical.
