Fully refined wax

Paraffin wax is generally white in color, whereas microcrystalline wax and petrolatum range from white to almost black. A fully refined wax should be virtually colorless water-white) when examined in the molten state. Absence of color is of particular importance in wax used for pharmaceutical purposes or for the manufacture of food wrappings. The significance of the color of microcrystalline wax and petrolatum depends on the use for which they are intended. In some applications (for example, the manufacture of corrosion preventives) color may be of little importance. 

The oil content of paraffin waxes is an indication of the degree of refinement, and fully refined wax usually has an oil content of less than 0.5%. Wax containing more than this amount of oil is referred to as scale wax, although an intermediate grade known as semirefined wax is sometimes recognized for wax having an oil content of about 1%. 

Features Fully refined wax with enhanced oxidation resist. 

Paraffin wax is macrocrystalline, britde, and is composed of 40—90 wt % normal alkanes, with the remainder C g—isoalkanes and cycloalkanes. Paraffin wax has Httle affinity for oil content fully refined paraffin has less than 1 wt % cmde scale, 1—2 wt %, and slack [64742-61-6] above 2 wt %. Within these classes, the melting point of the wax determines the actual grade, with a range of about 46—71°C. Typical properties of petroleum waxes are listed in Table 3.

The fully refined oil is bland, pale yellow and free from waxes and essentially free of phosphorus and sulphur. 

Ross Wax No. 130, No. 145 and No. 165 are fully refined, high melting point petroleum waxes. They are widely used in the formulating of PVC and electrical wire and cable compounds, as well as other applications which require a lubricant which is effective in small quantities without danger of exudation. 

This advantage is due to molecular structure and the lack of crystalline wax particles, present in some refined petroleum oils. Fully synthetic engine oil lubricants offer excellent low temperature flow and viscosity properties.(Demmin etal., 1992 Lakes, 1999).
