Slack Wax

Slack Wax is a by-product of the production of lubricating oils and a mixture of paraffin wax and oil originating from petroleum crude oil. During paraffin wax production, Slack wax has feuded into the system as raw material which is finally processed into different grades of Paraffin Wax after performing the refining processes, defiling, and bleaching. The oil extracted during the defiling process is a byproduct called ‘residue wax’ (aka Foots Oil). Slack wax is naturally brown in color, ranging from 3% oil content to 35%. Slack Wax can be classified as Heavy and Light. Heavy has a melting point of 62-66°C and Light has a melting point of 47-53°C.
