Slack wax supplier in drum and bag light and heavy grade

What is slack wax?

Slack wax has a relatively low melting point and is typically soft and pliable at room temperature. It contains a mixture of hydrocarbons, including both saturated and unsaturated compounds. The composition of slack wax can vary depending on the source of crude oil and the specific refining processes used.

Light and heavy slack wax and differences

A. Physical Properties:

Light: It is relatively softer and has a lower melting point compared to heavy slack wax. It may appear translucent or slightly opaque.

Heavy: It is harder and has a higher melting point compared to light slack wax. It tends to be more opaque or solid.

B. Composition:

Light Slack: It contains a higher proportion of lower molecular weight hydrocarbons, including lighter paraffinic compounds.

Heavy Wax: It contains a higher proportion of higher molecular weight hydrocarbons, including heavier paraffinic compounds.

C. Applications:

Light: Due to its softer nature and lower melting point, light wax is often preferred for applications that require flexibility, such as in the production of candles, rubber and tire industry, and as a lubricant or mold release agent.

Heavy: With its higher melting point and harder consistency, heavy slack is commonly used in applications that require durability, such as in the manufacture of matches, firelighters, polishes, coatings, and adhesives.

Micro slack wax

Lub cut containing a lot of paraffin wax and micro crystalline wax. Paraffin wax is produced through suiting  process from slack which has been producing by bleaching process.
Micro wax is a mixture consisting a lot of iso-paraffinic, some of N-paraffinic, naphthenic and aromatic hydrocarbons, with 31-50 carbon atoms. Molecular weights of commercial Micro crystalline wax is 450-700.

Properties of wax

Slack is yellow or brown , easy melt able product.It is one of the products of refineries which is mixture of paraffin wax and oil originated from petroleum crude oil. The Wax oil content can range from 5% to 30%.

The diluted oil is then chilled to -10°C to -20°C. Wax crystals will form, precipitate and removed by filtration. 

Usage and application of slack

The traditional usage is in the producing paraffin wax. And other major usage are for particle board and medium density fiberboard, cable filing compound , matches, candles, rust protective products and moisture vapor barriers.

Melting point of slack-wax

The melting point can vary depending on its composition, which in turn depends on the source of crude oil and the specific refining processes used. However, in general, the melting point range is typically between 50°C (122°F) and 70°C (158°F).

It’s important to note that different grade may have slightly different melting points. Light, which contains a higher proportion of lighter hydrocarbons, generally has a lower melting point compared to heavy, which contains a higher proportion of heavier hydrocarbons.

Slack wax price

Today slack wax price is on June 14 2023 is 800USD/MT average depend on packing and destination.

In summer time light price is more expensive than heavy and in winter time heavy is more expensive.
