Performance of pure palm oil and palm oil ester as lubricant / Khairul Syazwani Shahrudin

The use of renewable resources is one of the alternatives to overcome the dependencies on mineral oils. Vegetable oil and esters produced from vegetable oils are potential biodegradable lubricant. The use of palm oil as refine palm olein and industrial palm oil ester bio-based which are palmester 20...
