The production process of chlorinated paraffin includes thermal chlorination, traditional photochlorination, and catalytic chlorination methods, utilizing reactors such as kettle, tubular, and tower types, with varying technical levels and product quality. The thermal chlorination process takes 40-50 hours of reaction time, resulting in lower product quality; the traditional photochlorination method uses an internal light source, which has a short lifespan, is prone to clogging light tube sleeves, has low light transmittance, and is麻烦 to install and replace, presenting numerous inconveniences; the catalytic chlorination process requires organic oxides as initiators, posing certain risks.
       Not many people are aware of chlorinated paraffins, a substance that can be used to produce flame retardants and plasticizers for PVC. It is a derivative of paraffin and chlorinated hydrocarbons, characterized by low volatility, non-flammability, and flame-retardant properties. Below, staff from Hongxin Yuan discuss the physical characteristics of chlorinated paraffins.
       Paraffin wax chlorinated has a white or light yellow appearance, with a freezing point at 12°C, is non-flammable, and can prevent the combustion of other substances; it does not explode. It is insoluble in water but dissolves in most organic solvents. When chlorinated paraffin is heated with ethanol or oil to 130°C, it will decompose automatically.
       Paraffin wax chlorinated with varying chlorine content exhibits different forms, such as pale yellow liquids or white or pale yellow powders. It is a non-toxic, odorless material with flame-retardant properties, enhancing plastics, rubber, and other plastic materials. It can also be used as a surface treatment for outer packaging materials and as an additive for lubricating oils. When storing chlorinated paraffin temporarily, it should be kept in a cool, well-ventilated area, dry, and out of direct sunlight.
