Chlorinated paraffin is a chlorinated derivative of paraffin hydrocarbon, which has the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It can be used as a flame retardant and an auxiliary plasticizer for polyvinyl chloride. Widely used in the production of cables, floor materials, hoses, artificial leather, rubber and other products. As well as additives used in paints and lubricants.
The state of chlorinated paraffin is different due to its different chemical composition. Chlorinated paraffin 42 is light yellow viscous liquid, chlorinated paraffin 52 is light yellow to yellow oily viscous liquid, chlorinated paraffin 70 is dendritic powder, white or light yellow, etc. There are both solids and liquids, how to measure the specific gravity of chlorinated paraffin?
