偏苯三酸醍（TMA）是现代新材料的重要化工原料，可用于工程塑料，优质增塑剂，耐温绝缘漆，粉末涂料，水溶性涂料等多种高级涂料以及粘合剂、添加剂等。世界上仅美国、法国和日本等少数几个国家生产。由于该产品技术难度较大，我国虽从6O年代即投入开发，但至今仅有极少数厂家 TMA is an important chemical raw material for modern new materials and can be used for engineering plastics, high-quality plasticizers, temperature-resistant insulation paints, powder coatings, water-soluble coatings, and other advanced coatings as well as adhesives, additives, etc. . In the world, only a few countries such as the United States, France and Japan produce. Due to the technical difficulty of this product, although China has invested in the development since the 60’s, there are only a few manufacturers so far.
