聚氯乙烯塑料稀土稳定剂的研究开发现状和发展趋势

Process in Research and Development of Rare Earth Heat Stabilizer for PVC

热稳定剂是聚氯乙烯塑料(PVC)加工中的重要助剂,目前世界各国仍以传统的重金属类热稳定剂为主。未来热稳定剂行业的主要发展趋势是高效、低毒、复合型、无污染,重金属类稳定剂将逐渐被新型环保热稳定剂淘汰。稀土稳定剂作为我国独有的一类热稳定剂,具有热稳定性好、无毒、无污染等许多优点,同时我国具有丰富的稀土资源,因此大力发展稀土热稳定剂是我国热稳定剂行业发展的主要方向。

Heat stabilizers are key plastic processing additives. At present, traditional heavy metal heat stabilizers still keep dominance all over the world. The development trend of the heat stabilizer should be high efficiency, low toxicity, composite type and no pollution. Heavy metal stabilizers will be gradually substituted by new environmental heat stabilizers. As a sort of unique stabilizers in China, rare earth stabilizers have many specialties, such as favorable thermal stability, no toxicity and pollution. In addition to abundance of rare earth resource in China, vigorous research and application of rare earth heat stabilizers is the leading aspect of Chinese heat stabilizer sector.
