Classification of Paraffin

According to the degree of 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 the melting point, generally every 2 ℃, such as 52, 54, 56, 58 and other grades. Crude paraffin has a high oil content and is mainly used to make matches, fiberboards, tarpaulins, etc.

Microcrystalline paraffin

Microcrystalline paraffin is mainly composed of chain hydrocarbons, cycloalkanes and some straight chain hydrocarbons, and the molecular weight range is about 500-1000. This is a relatively small crystal, soluble in non-polar solvents, but insoluble in polar solvents.

Liquid paraffin

There are many types of liquid paraffin, and their lubricating effects are also different. In the extrusion process, the initial lubrication effect is good, and the thermal stability is also good. However, due to poor compatibility, the product tends to become sticky when the dosage is too much.
