T/JXSLXH 002-2024 Lanthanum stearate

Scope

Main technical content: Rare earth heat stabilizers, a unique type of PVC heat stabilizers in China, exhibit excellent heat stability, good transparency, electrical insulation, weather resistance, and excellent processing and storage stability. In particular, their non-toxic and environmentally friendly characteristics make rare earth heat stabilizers one of the few types of heat stabilizers that meet environmental protection requirements. At the same time, China's rare earth resources are very abundant, with sufficient raw material sources and low raw material costs, and the separation and processing technology is mature. Therefore, in-depth research and vigorous development of rare earth heat stabilizers to completely replace toxic heavy metal-based heat stabilizers and partially replace expensive organic tin-based heat stabilizers will be the main direction of future stabilizer industry development in China. Lanthanum stearate is an important heat stabilizer in rare earth heat stabilizers. However, there are no relevant national/industry standards for lanthanum stearate used in rare earth heat stabilizers, and international standards are also in a blank stage. To standardize the orderly and healthy development of the rare earth heat stabilizer industry and promote the improvement of the quality of lanthanum stearate products, it is proposed to formulate the "Lanthanum Stearate" group standard.
