    Polyol Esters Market Global Industry Analysis, Size

    Polyol Esters Market: Overview. Polyol esters are a form of esters formed by the esterification of fatty acids. The term ’polyol esters’ is an acronym for neopentyl polyol esters, which are obtained by the reaction of monobasic acids such as HNO 3 and HCl along with polyhedric alcohols which have neopentyl structure. Polyol esters are named after the alcohol which is utilized as its
