Paraffin waxes are classified according to oil content, melting point, and the amount of processing put in. At room temperature paraffin wax can be found in a solid state, when it reaches 37°C and above the wax will begin to enter a liquid phase.
At the simplest level, slack wax, a byproduct of base oil refining, is the feedstock from which different grades of more sophisticated waxes are produced. Fully refined waxes are white, odourless and tasteless, and have less than 0.5% oil content.
They are widely used for candle making and in the packaging industry as wax coatings for paper, film and foil substrates including corrugated board, cups and container. Waxes are marketed in either liquid or solid state.
Other common uses are for corrugated boxes, waxed papers, frozen food cartons and wrappers, paper cups, candles, cosmetics, rubber antioxidants, lumber end seal, adhesives, protective coatings, food additives, cheese dipping, crayons, moisture barriers, polishes, modelling clay, plus many others.
