Abstract : 

This research is to study the production of insulation from cogon grass fiber and rubber. By using cogon grass fiber mixed with rubber molding in the ratio 1:2, 1:3 and 1:4. Thermal conductivity properties of insulation from cogon grass fiber and rubber studied using the measure thermal conductivity according to standard ASTM C177-97. Fire spread of insulation from cogon grass fiber and rubber tested according to ASTM D 635-98, density of insulation from cogon grass fiber and rubber tested using principle of Archimedes. The Flexural strength and Modulus of Elasticity tested according to standard ASTM D 790(2007).
The thermal conductivity of the insulation from cogon grass and rubber showed that the thermal insulation from grass fiber and rubber, the ratio of 1:4 had the lowest thermal conductivity. The fire spread of the insulation from cogon grass fiber and rubber decreased when the amount of latex increased. The density of the insulation from cogon grass fiber and rubber decreased when the amount of latex decreased. The results of bendability and modulus of elasticity of the insulation from cogon grass fiber and rubber were increased when the rubber content increased. Comparison of thermal conductivity of the insulation from cogon grass and rubber with gypsum board, the insulation from cogon grass and rubber will be less. But it is higher than the natural rubber.
