AdtecTM133 (Iso 46) and 300 (Iso 68) are trimethylolpropane trioleate or known as TMPTO, having very high Flash and Fire Points over 300o C vs. mineral oils, 230o C, Max.  Since they are also biodegradable, many companies use them as a base oil for Hydraulics for mining, construction and forest equipment.  Both TMPTO esters can be used as an additive and as a lubricity additive or boundary lubricant, which is a must component in formulating metalworking fluids or industrial oils.  We have more polyol or regular esters that can be found under the heading of the Advance Technologies.”
