Paraffin. It is a product of distillation and further processing of paraffin crude oil, defined by a standard that allows three types of paraffin: a special S., refined R and unrefined N. Refined and special paraffins should be white, a crystalline mass with a possible yellowish tinge (when it comes to refined paraffin). The pour point of individual paraffin species is divided into two-stage ranges. For example. Refined paraffins are sold according to the following pour points: 46/48°C 50/52 °C, 52/54°C, 54/56°C, 56/58° C and 58/60 ° C: The pour point may not be lower than 50 ° G for S. for individual types, 46° C for R and 44 ° C for N. Paraffin is used in small amounts for electrical work (for waxing electrical cables before being pulled into Bergman tubes or armored steel in order to obtain a slip, for potting cables and wire terminals). Units for the performance of water and engineering works (geotechnical departments for drilling and foundation works) use paraffin to protect soil samples in jars or cylindrical vessels. Consumption standards: waxing the jar. — 25 g, double-sided waxing of the cylinder – 46 g. In addition, paraffin is used to make insulating masses, floor polishes, as an impregnation and for the production of candles. It is basically sold loose in blocks (plates) by weight.
