Slack Wax
Slack waxes are petroleum waxes, by-products from the production of base oil and of low to high viscosity. Low viscosity slack waxes are also known as paraffin slack wax, while high viscosity are micro slack waxes. Slack waxes are widely used in manufacturing kinds of compound wax to reduce the volume of semi or fully refined paraffin wax because of the cheaper cost, or for household products like candle and industrial products as moisture or rust resistance, or making petroleum jelly and lubricating grease as well wax blending, or as the raw materials for producing microcrystalline wax,etc.
