Scale Waxes
Scale waxes
contain between 1.5% and 5.0% -- less oil than slack waxes, but more than
the harder, refined or semi-refined paraffin waxes. Scale waxes
have negligible tensile strength. Melting points are between 118 and 137°F
(48 - 58°C).
Scale waxes of 124-126°F melting point grade are used in the match industry. Scale waxes of higher melting point are used in the kraft paper industry, e.g. builder’s papers, cement bag stock, roofer’s felt, car liners, and heavy kraft wrappings. Scale waxes of low oil content are required in the manufacture of crayons. Scale waxes also are used in making candles.
