Applications
With excellent high/low temperature property, good compatibility with additives, low volatility and low deposit formulation, TMT-1,-2,-3,-4,-5 are ideal synthetic ester basic fluid for high temperature chain oil, high viscosity synthetic air compressor oil and high temperature lubricating grease. Compared with pentaerythritol ester, trimellitate has higher viscosity, the amount of thickener additive may be decreased resulting in better high temperature property whentrimelliate is the basic fluid for the formulation of high viscosity chain oil and the thickener additive may be canceled when trimellitate is the basic fluid for the formulation of high viscosity synthetic air compressor oil.
