We use various laboratory instruments to properly test each wax blend and ensure consistent quality.

1. Differential Scanning Calorimeter (DSC)

This tool measures wax melt point through thermal analysis. Melt points vary depending on the wax blend. Different melt points are ideal for different applications.

The DSC measures the difference in the amount of heat required to increase the temperature of the wax sample compared to a reference sample. Both are kept at the same general temperature during the testing process. Most DSC tests gradually increase the temperature of a model with known properties in linear stages.

The DSC can then compare the differences between the two at established intervals. In other words, this equipment knows the already-established thermal behavior of the sample and determines the melting point by recording the temperature where the solid becomes liquid.

Our DSC equipment delivers fast results that help us stick to project turnaround time frames while providing superior quality waxes.

2. Brookfield Viscometer

This piece of lab equipment tests viscosity of a wax blend. Viscosity is a measure of a liquid’s resistance to flow. For example, water has a lower viscosity than honey.

Wax viscosity is crucial because of its impact on performance. Properties like temperature and shear rate can alter viscosity, changing how a wax blend will behave under certain conditions. Viscosity is also vital in petroleum-based applications, and this machine delivers reliable and accurate results.

It’s often easier and more accurate to measure viscosity than many of the other properties that affect it. In practice, understanding viscosity helps dictate the ideal solutions for wax handling. For example, suppose the wax blend needs higher viscosity during the application. In that case, the equipment introducing it must be capable of maintaining the correct temperature — a device that’s too cold may cause the viscosity to change.

3. Lovibond Colorimeter

This instrument measures color in natural waxes, including soy, candelilla and carnauba waxes. Wax color can indicate quality and can affect the look of the finished product. The colorimeter gives an unbiased color reading free of operator and environmental differences.

Colorimeters work by measuring wavelengths of light passed through a sample. Some completely exit the model while others remain. The colorimeter detects the wavelengths that come through. Using elimination, it’s possible to determine which ones the sample absorbed. This equipment delivers accurate and fast results that help us maintain consistency and quality confidence, even across batches.

4. Needle Penetrometer

This tool determines the hardness and softness of waxes by measuring the extent of a needle’s penetration into the wax. Wax hardness can vary significantly and influence other substance properties. A wax that is too hard may become brittle and prone to cracking. Similarly, one that is too soft may be unsuitable for specific applications and produce less than ideal results.

During this testing, a tapered spindle introduces force to a sample over a specific time interval. We strictly control environmental factors like ambient temperature throughout the process to ensure integrity and quality. The results of these tests also ensure high-quality product consistency, batch after batch.
