1. Introduction<\/h4>\n

Electronic packaging is the encapsulation of electronic components or chips in a protective housing to ensure that they operate properly under various environmental conditions. As electronic products become more and more integrated, the requirements for packaging materials are becoming increasingly stringent. Although traditional packaging materials such as epoxy resin, silicone, etc. have good mechanical strength and electrical insulation properties, they are prone to aging and cracking in high temperature and high humidity environments, resulting in a decrease in the reliability of electronic equipment. In addition, traditional materials will produce strong odors during the curing process, affecting the production environment and workers’ health. Therefore, developing a new packaging material with low odor and high performance has become an urgent need in the industry. <\/p>\n

As a new type of electronic packaging material, the low-odor reactive 9727 material has attracted widespread attention due to its excellent comprehensive performance and environmental protection characteristics. This article will introduce the materials in detail from the aspects of chemical structure, physical properties, process characteristics, etc., and combine practical application cases to explore its innovative applications in the field of electronic packaging. <\/p>\n

2. Chemical structure and synthesis principle of low-odor reaction type 9727<\/h4>\n

2.1 Chemical structure<\/h5>\n

The low odor reactive type 9727 is a composite material based on modified polyurethane (PU) and epoxy resin (EP). Its molecular chain contains a large number of active functional groups, such as hydroxyl (-OH), amino (-NH2) and epoxy (-C-O-C-), which can react chemically with crosslinking agents to form a three-dimensional network structure. By adjusting the proportion of different functional groups, the crosslink density and curing speed of the material can be controlled, thereby optimizing its physical properties and processing technology. <\/p>\n
