1. Introduction
Carboxyl terminated liquid polybutadiene rubber
CTPB. For there are carboxyl at both ends of the polymeric molecule, this polymer carries on the structurization along the carboxyl group, the distribution of the network is neat and without any free terminal. so it has excellent mechanical performance.
2. Usage
The product not only can be used in solid rocket propellant, but also can be used in elastomers, adhesives, sealing material, epoxy resin modification and electrical resistant material.
