Characterization of EIC Cellulose-Polyol Isocyanate Composite for Isolator

Sri Wuryanti

Abstract: Isolator is an inexpensive technology in improving energy saving, e.g., in heat pipes. Both Polyol Isocyanate and cellulose are good material examples to use as an isolator material. Each of them has some advantages and disadvantages. Therefore, to get characteristics that are required for an isolator material, a composite of Polyol Isocyanate and cellulose would be created. The result of the composite was then tested for its heat capacity by a Differential Scanning Calorimetry (DSC) and for its heat resistance by a Thermogravimetric Analysis. The determination of heat capacity value was conducted by comparing the experimental measurement and fitting. The highest heat capacity measurement value on the composite 2-3, was 0, 941 kJ/kg K and the lowest on the composite 1-1, was 0, 473 kJ/kg K. The highest heat capacity fitting value on the composite 2-3?, was 0, 938 kJ/kg K and the lowest on the composite 2-1?, was 0, 461 kJ/kg K. The result of thermogravimetric analysis showed that material decomposition occurred at a temperature of 235oC to 244oC. Meanwhile, the decomposition occurred at a temperature of 236 oC to 246 oC.
