Effect of Rubber Formula on Performance of Natural Rubber Based Foam for Insulating Ceiling Board Application

Abstract:

In this study, various NR:EPDM:EVA rubber foams were prepared. The ratios of NR:EPDM:EVA were at 50:20:30 and 50:10:40. The amounts of blowing agent, dinitrosopentamethylenetetramine (or Supercell DP) were 5, 6, and 7 part per hundred of rubber (phr). The vulcanizing agent, dicumyl peroxide (or DCP) loadings were at 0.7 and 1 phr. The influence of rubber formula on the performance of the obtained rubber foam was discussed here. The results showed that increasing EVA proportion and Supercell DP loading and decreasing DCP loading led to the decrease in density, thus giving the lower thermal conductive rubber foam which was suitable for using as an insulating ceiling board. However, the above condition gave the rubber foam with slightly inferior mechanical properties including lower hardness and higher % compression set.
