According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
Crude paraffin wax has a higher oil content and is mainly used for making matches, fiberboard, tarpaulin, etc. Fully refined paraffin and semi-refined paraffin are widely used, mainly used as components and packaging materials for food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, used for fruit preservation , Insulation of electrical components, improve rubber aging resistance and increase flexibility, etc.
Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and white or light yellow translucent solids. Paraffin wax is non-crystalline, but has a clear crystal structure. There is also artificial paraffin. Paraffin Wax,Bulk Paraffin Wax,Refined Paraffin Wax,Paraffin Wax Powder Henan Shunbang Chemical Industry CO.,Ltd , https://www.pvcresinchemical.com
Paraffin wax is a kind of petroleum processing product, a kind of mineral wax, and a kind of petroleum wax. It is a flake or needle-shaped crystal obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, pressing and dewaxing of lubricating oil fraction obtained from crude oil distillation, and then solvent deoiling and refining. Used to make higher fatty acids, higher alcohols, matches, candles, waterproofing agents, ointments, electrical insulating materials, etc.
