Chinese name：端羧基液体丁腈橡胶

CAS RN：68891-46-3

1、Product brief：

TY-CTBN25 is a flowable liquid oligomer composed of butadiene and acrylonitrile. It have high reactive carboxyl groups at both ends of the molecular chain than undergo chain extension or cross-linking reactions. These acrylonitrile groups offer composite with oil resistance, oil resistance, promote adhesion with polar surface, and improve blending performance, oil resistance, cracking resistance of thermosetting resins. Typical dosage 10~30%.
