1. melting point Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point as pure compounds. The melting point of a wax means that the melted paraffin sample is cooled under specified conditions, and the temperature at the stagnation period appears for the first time on the cooling curve. All kinds of wax products require good temperature resistance to wax, that is, they do not melt or soften at a certain temperature. According to the conditions of use, the areas and seasons used, and the use of the environment, a series of different melting points are required. The main factor affecting the melting point of paraffin wax is the degree of the selected raw material fraction, and the melting point of paraffin from the heavier fraction is higher. In addition, the oil content also has a great influence on the melting point of paraffin wax. The more oil in paraffin, the lower the melting point. 2. oil content Oil content is the amount of hydrocarbon containing low melting point in paraffin wax. Excessive oil content will affect wax color and storage stability, but also reduce its hardness. So removed from the vacuum distillate oil in the wax, but also needs the transpiration method or solvent deoiling, to reduce the oil content. But most paraffin products require a small amount of oil, which is beneficial to improve the gloss and demoulding properties of the products. 3. stability Paraffin products in the shape or coating process, long-term hot state, and contact with the air, if the stability is not good, it is easy to oxidation deterioration, color depth, or even stink. In addition, when used in light conditions, wax will also yellow. Therefore, paraffin wax requires good thermal stability, oxidation stability and light stability. The main factors affecting the stability of paraffin are the trace amounts of non hydrocarbon compounds and polycyclic aromatic hydrocarbons. In order to improve the stability of paraffin wax, it is necessary to refine the wax thoroughly to remove the impurities.
