The main difference between fully refined paraffin and semi refined paraffin is the oil content. The oil content of fully refined paraffin is less than 0.8%, and that of semi refined paraffin is less than 2.0%.
Fully refined paraffin refers to the product obtained by sweating or solvent deoiling with oily wax as raw material, and then clay or hydrofining.
Semi refined paraffin is not only an important petroleum product, but also an important material widely used in various industries and closely related to the lives of the people.
Fully refined paraffin is also known as refined white wax. The appearance of fully refined paraffin is white solid, and there are blocky and granular products. Its products have high melting point, low oil content, no bonding, no sweating, no greasy feeling at room temperature, good waterproof, moisture-proof and electrical insulation.
Semi refined into plate-shaped white solid. Its relative density increases with the increase of melting point. The product has good chemical stability, moderate oil content, good moisture-proof and insulation properties, and good plasticity. Semi refined paraffin wax produces candles with concentrated flames, smokeless and no tears.
Semi refined paraffin is used in candles, crayons, wax paper, general telecommunication equipment, short circuit, light industry and chemical raw materials.
Fully refined paraffin is mainly used in high-frequency porcelain, carbon paper, decorative sound-absorbing board and other products. It is also used in packaging, electronics, textile candles, crayons, match manufacturing and other industries.
