Product Details
Introduction
Polycarbosilane is an organosilicon polymer with Si-C bond as the main chain, which is easy to be heated, and the silicon hydrogen bond in the molecular chain can realize mutual cross-linking, thus it is widely used in the preparation of SiC ceramics, SiC-based composites and so on, and the polycarbosilane is an important precursor of ceramic-based composites. It is characterized by adjustable melting point range, adjustable molecular weight and distribution, and high ceramic conversion rate to suit different applications.
Application of Polycarbosilane
Silicon carbide (SiC) fibers
Polycarbosilane can be used to prepare silicon carbide fiber. Silicon carbide fiber is a high-performance ceramic fiber with advantages of oxidation resistance, high temperature resistance, low density, corrosion resistance, light weight, etc. It has a broad application prospect in many fields such as aerospace, automobile manufacturing, national defense and military industry, and sporting goods.
Silicon carbide fiber reinforced silicon carbide composite (SiCf/SiC composite)
SiCf/SiC composite is a ceramic matrix composites (CMCs) with silicon carbide fiber as the reinforcement and silicon carbide as the matrix. In addition to the excellent performance of silicon carbide, it also has the advantages of lightweight and high strength of reinforcing fibers, corrosion resistance and aging resistance.
Anti-oxidation coating (SiC coating)
The coating obtained after high-temperature depyrogenation of polycarbosilane has better anti-oxidation properties. At the same time, the hardness of the coating gradually increases with the increase of depyrogenation temperature. Silicon carbide (SiC) coating has extremely important application value in many fields such as aerospace, energy, and mechanical manufacturing due to its excellent high-temperature stability, high hardness, good chemical inertness and oxidation resistance.
