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.
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.
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.
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.
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.
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.
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.
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.
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.
ExxonMobil: ExxonMobil is a major global oil and gas company that produces a range of petroleum products.
Shell: Shell is another prominent energy company that manufactures various petroleum-based products.
Sasol: Sasol is an international integrated energy and chemical company that produces wax and other wax-related products.
PetroChina: PetroChina is one of the largest oil and gas companies in China.
Lukoil: Lukoil is a Russian multinational energy corporation involved in the production and sale of slack and other petroleum-based products.
Nippon Seiro: Nippon Seiro is a Japanese company that specializes in the production and distribution of wax and other waxes.
Top exporter countries are China, India, Iran, USA, German, Malaysia, South Africa, South Korea , UAE (Dubai), Egypt, Russia, Thailand, Turkey, France, Poland and Thailand.
Packing can be new or second hand 180 kg drums, 50Kg bag or 1000Kg jumbo bag,Iso tank or flexi tanks.
In winter time we export in jumbo bags with 1000 kg capacity , also small bags equal to 50 kg while the oil content is not more than 15%.
27129000 is HS code of slack and it is using for category of Other paraffin wax, microcrystalline petroleum wax, ozokerite, lignite wax, peat wax, other mineral waxes, and similar products obtained by synthesis or by other processes, whether or not coloureds.
