Crude scale wax refers to the paraffin wax that has undergone perspiration or solvent deoiling but has not undergone the final refining process. This slack wax still has a low melting point paraffin wax. In order to obtain a high melt paraffin wax, the crude scale wax needs to be refined again. Crude paraffin has higher oil content and darker product color. Due to the above and other reasons, the quality of slack wax is poorer than that of fully refined paraffin with the same melting point. Crude paraffin with higher oil content has lower tensile strength, and its structure is softer and fragile. Micro slack wax has good thermal stability, certain toughness and shrinkage.

Features of Crude Scale Wax
01
High oil content of the slack wax.

02
Darker color than semi refined paraffin wax.

03
Low tensile strength, soft and fragile structure of this low melting point paraffin wax.

04
Good thermal stability, certain toughness and shrinkage of this heavy slack wax.

Packaging and Storage of Crude Scale Wax
We offer a 50kgs woven bag and a 25kgs carton with plastic waterproof outer lining, store indoors to isolate the influence of sunlight and temperature on paraffin wax. As an experienced slack wax manufacturers, we provide crude scale wax at the best slack wax price in the slack wax market.

Slack Wax Vs Paraffin Wax
Slack wax is a petroleum paraffin wax with an oil content of between 3 and 50%. While fully refined paraffin wax has had nearly all of the oil refined out of it. The oil content of fully refined paraffin is generally less than 0.5%.

Crude paraffin with higher oil content than paraffin wax has lower tensile strength, and its structure is softer and fragile. Thus the quality of slack wax is poorer than that of fully refined paraffin with the same melting point.

For making paraffin wax, we usually remove the oil (de-oiling or de-waxing) from the crude scale wax. The oil is separated by crystallization. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled. As it cools, wax crystallizes out of the solution, leaving only oil.

As a professional wax supplier, we provide fully refined paraffin wax, candle wick, paraffin wax, candle wax wholesale, etc. For more information, please feel free to contact us!
