Polymethylsilane, abbreviated as PMS, plays a crucial role in the field of materials science as a precursor for the new generation of silicon carbide ceramics. 
At room temperature, PMS appears in a yellow semi transparent liquid form, which makes it easy to identify and operate due to its unique appearance. Its core advantage lies in the ability to generate β - silicon carbide during high-temperature cracking, which lays the foundation for its key role in the preparation of many high-end materials.
In terms of application, PMS performs exceptionally well. It is an ideal choice for preparing various types of composite ceramic precursors, and through precise process control, it can create high-performance silicon carbide ceramic materials. For Cf/SiC composite materials and SiCf/SiC composite materials, the participation of PMS ensures that the materials have good comprehensive performance, with significant effects in improving strength, toughness, and other aspects. At the same time, PMS also plays an irreplaceable role in the preparation of silicon carbide ceramic coatings, and the formed coating can provide excellent protection for the substrate material.
The products produced by PMS have many remarkable features. High temperature resistance enables it to maintain structural stability in high temperature environments, meeting the needs of high-temperature working conditions such as aerospace engine components; Its erosion resistance enables it to effectively resist material loss when facing extreme heat flow impacts; The ability to resist oxidation and corrosion has further expanded its application scenarios, and it can reliably serve in both chemical corrosion environments and strong oxidation atmospheres. Moreover, its low density makes materials prepared using PMS highly advantageous in fields with strict weight requirements, such as aerospace structural components.
From a structural perspective, PMS has a Si Si linear structure, with the main structural unit being - CH3 SiH -. The abundant Si-H bonds make the SiC fibers generated by its pyrolysis close to the stoichiometric ratio, which provides a good foundation for the preparation of SiC fibers and the development of related functional materials.
On a global scale, PMS production is concentrated in a few large producers, and China plays an important role in it, not only as a major producer but also as an important consumer country. Hunan Bowang Carbon Ceramic Co., Ltd. and its wholly-owned subsidiary Hunan Qianjin New Materials Co., Ltd. have achieved outstanding results in the research and production of PMS, and have built the first domestic 100t/a PMS production line and put it into operation, effectively promoting the development of the domestic PMS industry and the expansion of related applications.
In short, poly (methylsilane) (PMS) is becoming an indispensable key material in many advanced material fields due to its unique properties, wide applications, and reliable production guarantees.
