[Paraffin wax supply and procurement] What is the difference between semi-refined paraffin wax and fully refined paraffin wax?

Paraffin wax, also known as crystalline wax, is a hydrocarbon mixture with 18 to 30 carbon atoms. The main component is linear alkanes (about 80% to 95%). , there are also a small amount of alkanes with individual branch chains and monocyclic cycloalkanes with long side chains (the total content of the two is less than 20%). Paraffin wax is obtained from crude oil distillation and lubricating oil fractions through solvent refining, solvent dewaxing or wax freeze crystallization, press dewaxing to obtain wax paste, and then deoiled and refining to obtain flake or needle crystals. According to the different degrees of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin. Each type of wax is divided into different varieties according to its melting point, usually every 2°C, such as 52, 54, 56, 58 and other brands.

What is the difference between semi-refined paraffin wax and fully refined paraffin wax?

1. Different degrees of refining: the degree of refining of semi-refined paraffin is less than that of fully refined paraffin.

2. Different colors: highly refined paraffin wax is lighter in color, semi-refined paraffin wax is darker in color, and fully refined paraffin wax is lighter in color.

3. Different uses: Semi-refined paraffin wax is suitable for manufacturing candles, crayons, packaging paper, cultural and educational supplies, general telecommunications materials and wood processing, light industry, Chemical raw materials, etc. Fully refined paraffin wax is suitable for use in high-frequency porcelain, carbon paper, stylus wax paper, precision casting, decorative sound-absorbing panels, etc.
