The main role of paraffin in our country is to produce candles. The melting point is mainly due to the season of adaptation. The high melting point is suitable for the season with high temperature, and the low melting point is suitable for the season with low temperature. The main difference between fully refined paraffin and semi-refined paraffin is the amount of oil. The oil content of fully refined paraffin is less than 0.8%, the oil content of semi-refined paraffin is less than 1.8%, and the price difference is about 50 yuan/ton. The candles produced are almost invisible. What is the difference. Domestic candle factories mainly use semi-refined paraffin as raw materials, while domestic exports to the international market are mainly fully refined paraffin wax.

Fischer Tropsch wax is a methylene polymer that is an alkane synthesized using either syngas or natural gas. The Fischer-Tropsch wax with a high melting point (generally higher than 85°) is mainly composed of linear, saturated high-carbon alkanes with a molecular weight of 500-1000, which gives the chemical a fine crystal structure, high melting point and narrowness. Melting point range, low oil content, low penetration, low mobility, low melt viscosity, hardness, wear resistance and high stability.
