The Main Kinds of Paraffin Waxes
According to the degree of processing and refining, it can be divided into three types: fully refined paraffin wax, semi-refined paraffin wax and crude paraffin. Each type of wax is divided into different varieties according to the melting point, generally every 2 ° C, such as 52, 54, 56, 58 and so on.
It consists of chain hydrocarbons, naphthenic and some linear hydrocarbons. The molecular weight range is about 500-1000. This is a relatively fine crystal, soluble in non-polar solvents and insoluble in polar solvents.
There are many types of liquid paraffin, and the lubrication effect is 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 be sticky when used in an excessive amount.
Polyethylene wax refers to low molecular weight polyethylene or partially oxidized low molecular weight polyethylene having a molecular weight of 1500-25000. It has excellent fluidity, electrical properties and mold release.
It is a golden or amber viscous liquid that is non-flammable, non-explosive, and non-volatile. Chlorinated paraffin is an auxiliary plasticizer for polyvinyl chloride, which can replace a part of the main plasticizer. It is mainly used in PVC cable materials and water pipes, floor materials, film, artificial leather and so on.
