Paraffin wax classification

According to the degree 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 the melting point, generally every 2 ° C, such as 52, 54, 56, 58 and so on. Crude paraffin has a high oil content and is mainly used for making matches, fiberboard, canopy canvas, etc.

1.Microcrystalline paraffin wax
Microcrystalline paraffin is mainly composed of a chain hydrocarbon, a cycloalkane and some linear hydrocarbons, and has a molecular weight range of about 500-1000. This is a relatively fine crystal, soluble in non-polar solvents and insoluble in polar solvents.
2. Liquid paraffin wax
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.
3. Polyethylene wax
(ACPE for short)
Polyethylene wax refers to low molecular weight polyethylene or partially oxidized low molecular weight polyethylene having a molecular weight of 1500-25000. It is in the form of granules, white powder, lumps and milky white wax. It has excellent fluidity, electrical properties and mold release.
4. Semi-refined paraffin wax
It is a granular white solid whose relative density increases as the melting point increases. The product has good chemical stability, moderate oil content, good moisture and insulation properties, and good plasticity. The semi-refined paraffin-produced candle flames are concentrated, smoke-free, and do not shed tears. Used for making candles, crayons, wax paper, general telecommunications equipment, as well as short-circuit and light industry, chemical raw materials, etc.
5. Chlorinated paraffin wax
Chlorinated paraffin is a golden or amber viscous liquid that is non-flammable, non-explosive, and extremely volatile. Soluble in most organic solvents, insoluble in water and ethanol. Heating to 120 ° C or more slowly decomposes, can release hydrogen chloride gas, iron, zinc and other metal oxides will promote its decomposition. Chlorinated paraffin is an auxiliary plasticizer for polyvinyl chloride. Low volatility, non-combustible, odorless, non-toxic. This product replaces a part of the main plasticizer, which can reduce the cost of the product and reduce the flammability. Mainly used in PVC cable materials and water pipes, floor materials, film, artificial leather and so on.
