Commercially available Polycarbosilane(PCS) from TONG LI TECH


Polycarbosilane(PCS) is the most typical polymeric solid precursor with ma in chain of Si-C to high temperature resistant SiC ceramics. TONGLI_Polycarbosilane with high quality now available commercially.




Benefits of TONGLI_Polycarbosilanes (PCS)

- High thermal stability and purity of 99%.

- Well-distributed molecular weight which molecular weight distribution index is around 2.0.

-High ceramic yields of more than 55wt%

-Patented production method with good diathermancy and reaction uniformity has a high yield, high synthesis efficiency and short preparation time. No harmful gases released out during the production process.

- Self-curing.

- Low oxygen content.




TONGLI_Polycarbosilane (PCS) is a preceramic polymer for silicon carbide, e.g. in the formation of silicon carbide fibers, silicon carbide nanopowders, microporous silicon carbide(SiC)-based membranes and SiC preforms as well as coatings and binders for particles, and especially very good for C/SiC composites.




TONGLI_Polycarbosilane(PCS) is not considered hazardous and therefore is not regulated by DOT or IATA.




- TONGLI_Polycarbosilane(PCS) has a shelf life of or more than six months.

- As PCS is sensitive to oxygen, it should be kept at no-air and dry conditions, it's best to keep it under inert gas protection.




With very good electrospinnablity.

With very good carbonized result.
