Paraffin is a kind of mineral wax and petroleum wax; It is a flaky or needle-like crystal obtained by solvent refining, solvent dewaxing, or wax freezing crystallization and press dewaxing of lubricating oil fraction obtained from crude oil distillation to obtain wax paste, and then solvent deoiling and refining.

Also known as crystalline wax, it is a mixture of hydrocarbons with about 18 ~ 3 carbon atoms. The main components are straight-chain alkanes (about 8% ~ 95%), and a small amount of alkanes with individual branches and monocyclic alkanes with long side chains (the total content of the two is less than 2%).

the main quality indexes are melting point and oil content, the former indicates temperature resistance and the latter indicates purity. Each type of wax is divided into different varieties according to its melting point, generally every 2℃, such as 52, 54, 56, 58 and other brands.
