Separated by the melting point, the paraffin wax is usually at 2 C, as in us: 54-56 C, 56-58 C, 58-60 C, 60-62 C, 64-66 C. All types of wax products must withstand cold well for paraffin wax, which means that it does not melt or soften and does not deform at a specific temperature. Depending on the conditions of use, locations and seasons of use, as well as differences in the method of use, commercial paraffin wax is required for a series of different melting levels. 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.
