Classification Of Paraffin Wax
Paraffin is a kind of mineral wax and also a kind of petroleum wax; it is a piece or needle like crystallization from the distilled oil distilled from crude oil through solvent refining, solvent dewaxing or wax freezing crystallization and squeezing dewaxing. It is also called crystalline wax with a carbon atom of about 18~30 of hydrocarbon mixtures, which are mainly divided into direct alkanes (about 80% to 95%), and a small amount of alkanes with individual branched chains and mono cyclic naphthenic hydrocarbons with long side chains (less than 20% of the total amount). The main quality indicators are melting point and oil content. The former represents heat resistance and the latter indicates purity. Each type of wax is also divided into different types, such as 52, 54, 56, 58 and so on, according to the melting point at 2 degrees. According to the degree of processing and refining, it can be divided into 3 types: fully refined paraffin, semi refined paraffin and crude paraffin.
