Introduction<\/h3>\n

Polyurethane (PU) is a widely used polymer material. Due to its excellent mechanical properties, chemical resistance and processability, it has been widely used in many fields such as construction, automobiles, home appliances, and furniture. application. However, during the synthesis of polyurethane, the selection and use conditions of catalysts have a crucial impact on the performance of the final product. Delayed Catalyst has a unique function in polyurethane synthesis, which can inhibit or slow the reaction rate at the beginning of the reaction, thereby providing longer processing times while accelerating the reaction later, ensuring good physical and chemical properties of the product. <\/p>\n

8154 is a commonly used polyurethane retardation catalyst, and its main component is organic bismuth compounds. Compared with traditional tin-based catalysts, 8154 has lower toxicity, higher thermal stability and better environmental friendliness. Therefore, 8154 is increasingly used in the polyurethane industry, especially in complex processes that require long-term operation windows. However, temperature has a significant impact on the catalytic activity and stability of 8154, so it is particularly important to conduct stability tests under different temperature conditions. <\/p>\n

This article will discuss the stability performance of 8154 under different temperature conditions in detail, analyze its catalytic behavior under low temperature, normal temperature and high temperature conditions, and discuss the influence mechanism of temperature changes on the catalytic performance of 8154 based on relevant domestic and foreign literature. Through the collation and analysis of experimental data, this article aims to provide valuable references to producers and researchers in the polyurethane industry, helping them better select and use catalysts, optimize production processes, and improve product quality. <\/p>\n

8154 Basic parameters of catalyst<\/h3>\n

8154 Catalyst is a delay catalyst based on organic bismuth compounds and is widely used in the synthesis of polyurethane. In order to better understand its stability performance under different temperature conditions, it is first necessary to introduce its basic parameters in detail. The following are the main physical and chemical properties and technical parameters of the 8154 catalyst:<\/p>\n

1. Chemical composition<\/h4>\n

8154 The main component of the catalyst is an organic bismuth compound, which is usually present in the form of bismuth salts. Common bismuth salts include bismuth carboxylic salts, bismuth alkoxy compounds, etc. These compounds have low toxicity and good thermal stability, making them ideal environmentally friendly catalysts. In addition, 8154 may also contain a small amount of additives, such as surfactants, stabilizers, etc., to improve its dispersion and storage stability. <\/p>\n
