Hydroxyl value is defined as the number of hydroxyl end-groups per gram of a sample. It is a very important quality parameter, and a typical measure to determine molecular weight and calculate the functionality of polyols. A polyols is an alcohol with more then two reactive hydroxly groups per molecule. Polyols are the starting material for … Read more

To date, palm oil mills have generally complied with the 100ppm BOD requirement of POME discharged into a watercourse. However, the current 20ppm requirement by the Department of Environment (DOE) in some sensitive areas, especially those involving tourism activities in Sabah and Sarawak, is difficult to comply with due to uncertainties in the performance of … Read more

Crude petroleum contains sulphur compounds and most of them are removed during the refining process. The presence of some sulphur compounds remaining in the diesel  fuel can have a corrosion, it is used as an indicator of the cohesiveness of a fuel. Main Research: Yung Chee Lian

Cetane number is a defined parameter designed to provide an indication of the ignition quality of diesel fuels. A higher cetane number means that the fuel has better ignition quality than fuels with lower cetane numbers. Cetane number is a measure of a fuel’s ignition delay, which is the time period between the start of … Read more

With the growing focus today on noise-control issues and the emergence of sound quality as an important aspect of product design, acoustic material testing is becoming increasingly relevant to researchers, engineers, designers and manufactures from a broad range of industries. Products like bio-composites, fibre-reinforced plastics, felt and insulators are being used as sound dampening components, … Read more
