Paraffin wax is a mixture of higher alkanes, mainly n-docosane and octadecane, containing about 85% carbon and about 14% hydrogen. Accessories added include white oil, stearic acid, polyethylene, spices, etc. Among them, stearic acid mainly increases softness, and the specific amount depends on which kind of candle is produced.

Paraffin wax category:
1, microcrystalline paraffin
Microcrystalline paraffin is mainly composed of paraffins, cycloalkanes and some straight-chain hydrocarbons, and its molecular weight range is about 500- 1000. This is a relatively fine crystal, which can decompose nonpolar solvents without decomposing polar solvents.
2. Liquid paraffin
There are many kinds of liquid paraffin, and the lubrication effect is different. In the extrusion process, the initial lubrication effect is good and the thermal stability is good. However, due to poor compatibility, it is easy to get sticky when the product is excessive.
3. Polyethylene wax
Polyethylene wax refers to low molecular weight polyethylene with molecular weight of 1500-25000 or partially oxidized low molecular weight polyethylene. It exists in the form of particles, white powder, block and milky white wax. It has excellent fluidity, electrical performance and demoulding performance.
