Fully Refined Paraffin Wax is the most commonly used commercial wax. In industrial applications, it is often useful to modify the crystal properties of the paraffin wax, typically by adding branching to the existing carbon backbone chain. The modification is usually done with additives, such as EVA copolymers, microcrystalline wax, or forms of polyethylene. The branched properties result in modified paraffin with a higher viscosity, smaller crystalline structure, and modified functional properties. Pure paraffin wax is rarely used for carving original models for casting metal and other materials in the lost wax process, as it is relatively brittle at room temperature and presents the risks of chipping and breakage when worked.
Semi refined paraffin waxes contain more than 1% oil compared to fully refined paraffin which typically contains less than 1% oil content. The oil content varies as per the quality of the wax which could go upto 5-7% oil content. Semi Refined Paraffin waxes are inert, insoluble in water and alcohol, and only slightly soluble in absolute alcohol. Polishes, Tires and rubber product, Carbon paper, crayons and pencils etc.
