Separated by oil knowledge, it can often be divided into: Fully refined paraffin, Semi-refined paraffin, and Crude wax.
In addition, paraffin wax needs to be heat resistant, oil resistant and light resistant, otherwise the color will turn yellow after application. Excessive oil exposure impairs the color and stability of the paraffin wax, and also reduces its hardness. The main factors that affect the stability of paraffin wax are its non-hydrocarbon compounds and the low concentration of hydrocarbons.
