An understanding of component-properties relationship of high-temperature resistant addition-cure liquid silicone rubber: A review

The demand for addition-cure liquid silicone rubber (ALSR) with high temperature resistance in various fields is continuously surging, propelled by the rapid advancement of industries such as aerospace, electronics, and transportation. However, the intricate relationship between the structure and performance of ALSR remains unclear. Therefore, this present study aims to conduct a comprehensive review of recent research advancements in ALSR. More specifically, it pertains to the thermal degradation behavior of silicone rubber; providing a comprehensive review of four components in high-temperature resistant ALSR, including basic polymers, crosslinking agents, fillers, and catalysts; elucidating the relationship between each component and heat resistance properties; as well as addressing the future challenges about high-temperature resistant ALSR. This review provides valuable insights into the design of a high-temperature resistant ALSR.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
