Product details

1. Polycarbosilane:

Poly carbon silane is a kind of organic silicon polymer whose main chain consists of Si -C key , and containing active Si – H. Under normal temperature, it is light yellow viscous or viscous amber sate, with low oxygen content, and soluble and fusible. Through adjustment on its molecular weight, it can meet different application requirements.
