What is dibutyl phthalate?
Dibutyl phthalate is an important general-purpose plasticizer, mainly used in the processing of polyvinyl chloride resin, but also in the processing of chemical fiber resin, acetic acid resin, ABS resin and rubber and other high polymers.
Function of dibutyl phthalate
Colorless transparent oily liquid, slightly with fragrance, Molecular formula C16H22O4, Molecular weight 278.35, Relative Density (d2520) 1.045, with a strong ability to dissolve. have excellent compatibility with most organic solvents and hydrocarbons nitrocellulose, polystyrene and others , cellulose resin and PVC primary plasticizer. .
Application of dibutyl phthalate
Especially suitable for nitrocellulose coating with excellent solubility, dispersion, adhesion, flexibility and stability of the film are good; good compatibility with pigments for the coloration of the film, artificial leather and other plastic products; also For PVC, alkyd resins, ethyl cellulose and neoprene as plasticizer and softener in order to improve the resilience of the article.
