It is also called synthetic paraffin, which comes from the by-product of Fischer Tropsch synthesis of artificial petroleum, and is called Fischer Tropsch wax. Tasteless, odourless, white or yellowish fine bright crystal, free of branched hydrocarbons. The melting point of hard paraffin was 45-68 ℃ higher than that of paraffin. Molecular weight 300-450. The number of carbon atoms is over 34-40.
It has good crushing resistance, excellent insulation and strong water resistance. It is prepared from the wax washing heavy oil by decompressing, fractionating and refining. It can also be refined from the attachments scraped off the catalyst for Fischer Tropsch synthesis of petroleum. It can be used on special occasions where the wax can not meet the requirements, as insulation materials for demanding telecommunication components, sealing materials for aviation components, etc. It can also be used in food and cosmetics.
