Loading Silica for Supporting Carbon Black Filler to Prevent Degradation Natural Rubber Caused DME

DME (Dimethyl Ether) is the future environmental friendly fuel. Some parts of equipment for transporting are using rubber as a hoses or seals. This research about natural those applications. The influential part in manufacture products fillers. use filler depends on what product will be made. nature have high permeability and easy to absorb into plastic. In such that, plastic could damaged not durable. order determine type degradation, number samples were immersed liquid DME. ratio loading carbon black/silica was varied. causes two types namely absorption extraction. addition composition can reduce extraction, which cause reduction percentage decrease value change mass tensile strength. On other hand, increase changes hardness. higher loading, crosslink density lower scorch time. presence silica further enhance well Therefore, affect decreasing swelling level shrinking. general, mixture slightly lowering strength, but affecting elongation at break. before after soaking with
