Carbon Black Content Apparatus

Carbon Black is one of the most important filler in plastics materials. It not only acts as pigment but also as an UV absorber. However the level of addition of this filler influences the plastics behaviour a lot and hence requires to be well controlled. This is major reason of determining the percentage of it in given polymer mass. This is particularly more effective in polyolefins and polythylenes in particular. The method consists of pyrolysing the sample in an inert atmosphere and considering the gravimetric difference. Compact furnace with double thermal insulation for the best operator ease. Alongwith are best quality galsswares for longer durability but with easy availability. The thermal glasswares are fine quality imported high temperature quartz glass. The heaters are custom made for better reliability and longer life. They are made from best quality alloys to avoid premature fusions. The temperature is controlled by electronic solidstate controller and built in rate-of-rise device to avoid practically any over scoots and better temperature stability.
