Definition Of Slack Wax
Slack Wax is mixture of paraffin wax and oil originated from petroleum crude oil. Paraffin wax refers to a mixture of alkanes within the Carbon no in 20 ≤ n ≤ 40 ranges. It is a byproduct derived in the process of producing Lube cut. During paraffin wax production, Slack wax is 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 10% oil content to 35%. Slack Wax can be classified as Heavy and Light. Heavy has melting point of 62-66°C and Light has melting point of 47-53°C.
The traditional usage of this product is in the production of fully refined paraffin wax which is the main raw material for candle manufacturing. Slack wax other major usage are for particle board and medium density fiber board, cable filing compound, paraffin wax, matches, candles, rust protective products and moisture vapor barriers.
Applications Of Slack Wax
