Product Name: Carboxyl-Terminated Liquid Polybutadiene Rubber Liquid Rubber Ctpb Model NO.: QL02 Color: Yellow Composition: Organic Material Promoter Composition: Plasticizer Characteristic: Waterproof Main Agent Composition: Natural Polymer Classification: Thermosetting Material: Polyester Application: Construction, Footwear & Leather Morphology: Water Emulsion Bonding Function: Industrial Use Trademark: QL Transport Package: Plastic Barrel Origin: Shandong China Product Description 1. IntroductionCarboxyl-terminated liquid polybutadiene rubber is generally called CTPB for short. 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. ApplicationThe 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.3.
