Product Description

CTBN Liquid Rubber with Enhanced Adhesion, Improved Compatibility, and Enhanced Impact Resistance for Industrial Applications

Carboxyl-terminated Polybutadiene Acrylonitrile Liquid Rubber (CTBN)

Carboxyl-terminated polybutadiene acrylonitrile liquid rubber (CTBN) is a unique type of liquid rubber combining polybutadiene and acrylonitrile, featuring carboxyl functional groups at the chain ends. This modification significantly enhances its compatibility, leading to improved adhesion and streamlined processing.

Key Benefits

Enhanced Adhesion: Carboxyl termination promotes strong bonding to various substrates
Improved Compatibility: The combination of polybutadiene and acrylonitrile offers broad compatibility with other polymers and additives
Versatile Processing: Liquid form allows for easy mixing and application in diverse processes
Enhanced Impact Resistance: Polybutadiene component contributes to improved flexibility and impact resistance in final products

Target Industries and Applications: Adhesives, Sealants, Coatings, Composites, and Elastomers
