Slack Wax

Slack Wax

Slack waxes are minimally refined high oil products. They are derived from lubricating oils and often find applications “as they are” with relatively high oil content, or are further processed to produce more refined waxes.

Most slack waxes do not meet FDA requirements for food packaging. Slack waxes range from 55°C to 65°C in melting point, and their oil content ranges from 3.0% to as much as 11%. Slack waxes are widely used in the production of wax emulsions, construction board, matches, candles, rust protective products and moisture vapor barriers.

One of the many products derived from refining is lubricating oil, from which a byproduct called slack wax is obtained. Slack wax is a mixture of oil and wax. It is the product, which serves as IGI’s feedstock and that is further refined and blended to create value-added petroleum wax products.
