Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

Shanxi Metrology Institute's scientific and technological research project won the third prize of Shanxi Science and Technology Progress Award
China Instrument Network Instrument R&D recently reported that the Shanxi Provincial People's Government announced the 2017 Shanxi Science and Technology Award (Jin Zheng Fa [2019] No. 5). The project titled "Application Research on Calibration Method of Chemical Oxygen Demand (COD) Online Monitoring Equipment," led by the Shanxi Metrology Institute under the Shanxi Science and Technology Department, has been awarded the Third Prize in the Shanxi Science and Technology Progress Award.
This research focuses on developing a practical calibration method for COD online monitoring equipment, aligned with national metrology standards and real-world usage scenarios. By utilizing high-purity glucose as a reference material, the study ensures accurate traceability for low-range COD monitors. The developed method has been tested across multiple applications, resulting in a comprehensive and standardized technical framework.
The outcomes of this project have been widely adopted as local metrology guidelines in Shanxi Province, enabling full coverage of on-site calibrations for COD online monitors. This advancement not only supports the improvement of national metrological standards but also provides essential technical support for the legal management of environmental monitoring. With its strong potential for broader application, the project has reached a leading position domestically.
