This is a technical specification sheet for paraffin wax grades, listing their physical and chemical properties.
This document is a technical specification sheet for paraffin waxes, intended for industrial buyers and quality control professionals. It covers two main categories of paraffin wax: fully refined wax and scale wax, each with detailed property data.
The first section explains that paraffin waxes are separated from crude oil during light lubricating oil production. Waxes are categorized by oil content and refinement degree: slack wax (5-20% oil), scale wax (1-5% oil), and fully refined wax (less than 0.5% oil, hydro treated or clay treated). Common applications include candles, corrugated boxes and paper coating.
The main body of the document is a table listing fully refined wax grades from FR50/52 to FR70/72. For each grade it provides the melting point range in Celsius and Fahrenheit (ASTM D87), maximum oil content (ASTM D721), minimum Saybolt color number (ASTM D156), needle penetration range at 25°C (ASTM D1321), and flash point (ASTM D92).
A second table covers scale wax grades from SR50/52 to SR70/72. These grades have a higher maximum oil content of 1.5% and a lower minimum color requirement of 20. The same test methods are used for melting point, penetration and flash point as for the fully refined grades.
All grades listed in both tables have no data provided for kinematic viscosity at 212°F (ASTM D445) or ultraviolet absorbance per 21CFR172.886(b), indicated as N/A in the specification columns.
