Take a look at the application note that reveals how to measure dropping point in waxes according to ASTM D3954. |
Waxes are organic compounds derived from various plants and animals, known for their hydrophobic properties. This unique characteristic makes them valuable in numerous industrial applications. From candle manufacturing to waterproof coatings, waxes play a significant role across many branches of the chemical industry.
Importance of Dropping Point Analysis
The dropping point is a critical parameter, defining the specific temperature at which a liquefied substance first drops from a standardized, chromium-plated cup into collector glass. This measurement is essential for ensuring consistency and reliability in the quality assessment of various waxes, including paraffin, microcrystalline polyethylene, and oxidized Fischer-Tropsch waxes. By adhering to ASTM D 3954, which provides a standardized method for conducting dropping point analyses, METTLER TOLEDO ensures that your quality control processes meet both national and international standards.
Our Excellence Dropping Point Systems, featuring the DP70 and DP90 models, are expertly designed for precise measurement of dropping points. Each system includes a complete Dropping Point Accessory Box and is compatible with various wax samples. Additionally, these devices offer predefined methods to streamline testing and adjustments as needed. Notably, the Dropping Point Devices have an extensive temperature range, from -20 °C (DP90) to 400 °C, effectively accommodating the dropping point temperatures of waxy samples. Our advanced video processing algorithms allow for fully automated and unattended measurements, ensuring reliable results every time. Trust METTLER TOLEDO for all your dropping point analysis needs and experience the assurance of consistent quality in your raw materials and final products.
