Effect Of Combination Ultrasonic And Ball Milling Techniques Of Fillers Dispersion On Mechanical And Pgysical Properties Of Natural Rubber Latex Films

The addition of commercial fillers like calcium carbonate, titanium dioxide, kaolin, carbon black and silica in Natural Rubber (NR) latex compounds has reduced the mechanical properties of NR latex films due to the destabilization effect in the NR latex compounds which govern by the dispersion quali...
