The percentage of oil is given as the weight of oil to the total weight of the wax sample. Waxes with low oil content are more brittle and hard and have a higher melting point, whereas those with higher oil content, which are soft and plastic, run out of oil over time. Measurement assists manufacturers in customizing wax properties to suit their use in making candles, formulating coatings, and food packaging materials.
ASTM D721 is used to determine the oil content of petroleum waxes. ISO 2908 works best with low and moderate oil contents of wax because it has accuracy in carrying out separation using solvents.
ISO 2908 Applications in Industry
This method is often used in candle-making industries, packaging materials industries, coatings industries, and polish and adhesive industries, where the oil content influences the quality and stability of the product. Refiners and quality control laboratories use this technique to investigate production consistency as well as to check the buyer’s specifications.
ISO 2908 Materials Commonly Tested
One can mention imperfect dissolution of wax because of the lack of heating, precipitation because of solvent contamination, or an inappropriate cooling procedure that results in incomplete precipitation. These problems can be reduced with the maintenance of correct cooling temperatures and the usage of fresh, dry MEK.
ISO 2908 Common Challenges and Troubleshooting
Imperfect dissolution of wax because of the lack of heating, precipitation because of solvent contamination, or an inappropriate cooling procedure that results in incomplete precipitation. These problems can be reduced with the maintenance of correct cooling temperatures and the usage of fresh, dry MEK.
ISO 2908 Safety and Best Practices
MOK is also flammable and ought to be poured in a highly ventilated place, free of ignition points. The operators must use the safety goggles, gloves, and lab coats. The disposal of waste solvents and residues should be done as required by the environment.
Importance of ISO 2908 Test Method
The oil content is crucial in the prediction of the physical behavior of petroleum wax in its intended end-use behavior. The procedure described in this method is reliable, repeatable, and internationally recognized. It thus can be used to ensure consistency in the control of quality and the comparability of results obtained in different laboratories and production facilities.
