Paraffin classification

According to the degree of processing refinement, 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, such as 52, 54, 56, 58, etc., according to its melting point, usually every 2 ℃. Coarse paraffin has a high oil content and is mainly used in the manufacturing of matches, fiberboards, canopies, and canvas.

Microcrystalline paraffin

The composition of microcrystalline paraffin is relatively complex. In addition to normal alkanes, it also contains different amounts of multi branched isomeric alkanes and cyclic compounds. The number of carbon atoms in hydrocarbon molecules is about 40-45. [6] This is a relatively small crystal that is soluble in non-polar solvents and insoluble in polar solvents.

Liquid paraffin

There are many types of liquid paraffin, and their lubrication effects are also different. In the early stage of extrusion processing, the lubrication effect is good and the thermal stability is also good. However, due to poor solubility, the product is prone to sticking when used in excessive amounts.

Polyethylene wax

(abbreviated as ACPE)

Polyethylene wax refers to low molecular weight polyethylene or partially oxidized low molecular weight polyethylene with a molecular weight of 1500-25000. It is in the form of granules, white powder, blocks, and milky white wax. Has excellent fluidity, electrical performance, and demolding ability.

Semi refined paraffin wax

It is a granular white solid, and its relative density increases with the increase of melting point. The product has good chemical stability, moderate oil content, good moisture resistance and insulation performance, and good plasticity. Candles produced from semi refined paraffin have concentrated flames, no smoke, and no tears. Used for making candles, crayons, wax paper, general telecommunications equipment, as well as short circuits and light industry, chemical raw materials, etc.

Chlorinated paraffin

Chlorinated paraffin is a golden or amber viscous liquid that is non flammable, non explosive, and has minimal volatility. Soluble in most organic solvents, insoluble in water and ethanol. Heating to above 120 ℃ slowly decomposes on its own, releasing hydrogen chloride gas. Oxides of metals such as iron and zinc promote their decomposition. Chlorinated paraffin is an auxiliary plasticizer for polyvinyl chloride. Low volatility, non flammable, odorless, and non-toxic. This product replaces some of the main plasticizers, which can reduce product costs and reduce combustibility. Mainly used for PVC cable materials, water pipes, flooring materials, films, artificial leather, etc.
