Effect of Carbon Black Type on the Thermal Properties of Fluoroelastomer

ABSTRACT

The main objective of the present work is to study the effect of carbon black (CB) microstructure on the thermal properties of Fluoroelastomer (Viton A). In order to study the microstructure effect of CB, three types of CB (N330, N660 and N990) were selected. Melt mixing method was employed for compound preparation. Vulcanization, mechanical properties before and after oxidative aging in oil and oven conditions, and thermal stability of the compounds were evaluated. Vulcanization characteristics of compounds revealed that CB with higher structure has higher minimum and maximum torque and lower vulcanization rate. Mechanical stability in oxidative aging and resistance to thermal degradation were all increased in CB containing composites. It can be attributed to CB characteristics and CB-polymer interaction which is different in various CB containing samples.
