Scale Waxes

Scale Waxes

IRM Scale waxes differ from their paraffin counterparts due to a lower degree of refinement resulting in a higher oil content of 1.5% - 5.0%. The greater oil content increases the ability to manipulate the wax compared to the harder and more brittle paraffin wax family - still scale waxes have a negligible tensile strength. Melting points are between 122 and 145°F (50 - 63°C).

Scale waxes of 124 to 126°F melting point are used in the match industry. Scale waxes of higher melting point are used in kraft paper industry, e.g. builder's papers, cement bag stock, roofing felt, car liners, and heavy kraft wrappings. Scale waxes of low oil content are required in the manufacture of crayons. Scale waxes are also used as a blend or as alone in making candles.
