Paraffin wax is a colorless to white translucent lump. Pure paraffin is white, while paraffin containing impurities is yellow. It is tasteless, odorless, and greasy. Soluble in ether, chloroform, benzene, petroleum ether, volatile oil or various fatty oils, slightly soluble in ethanol. It has stable chemical properties and does not react with acids, alkalis, oxidants and reducing agents. It will turn yellow under ultraviolet irradiation, can burn and decompose, and is stable at room temperature. It is understood that paraffin wax is divided into crude paraffin wax, semi-refined paraffin wax, fully refined paraffin wax and food wax according to the degree of refining of paraffin wax. The deeper the degree of refining, the lighter the color and the better the product quality and the higher the production cost.
Semi-refined into a plate-like white solid. Its relative density increases with the rise of melting point. The product has good chemical stability, moderate oil content, good moisture-proof and insulation properties, and good plasticity. Candles produced from semi-refined paraffin wax have a concentrated flame that is smokeless and does not shed tears.
Semi-refined paraffin can be used in these material products:
Downgraded use of various fully refined wax applications;
Isolation Molding materials: plastic, rubber and other mold release agents, fiberglass products mold release;
Solid lubricating materials: ship launching lubrication, low-speed ski lubrication, low-speed lubrication of underwater machine parts;
Coating materials with low protection level;
Precision casting low-temperature mold materials
