उत्पाद का वर्णन


Carboxyl-terminated Polybutadiene (CTPB)  Liquid Polymer For Adhesives Sealants And Coatings


Product Description

Carboxyl-Terminated Polybutadiene (CTPB)

Description:
Carboxyl-terminated polybutadiene (CTPB) is a liquid polymer with reactive carboxyl (–COOH) end groups, derived from polybutadiene rubber. It is widely used in high-performance adhesives, sealants, propellants, and coatings due to its excellent flexibility, chemical resistance, and curing properties.



Specification 

Property Value / Range
Chemical Structure Polybutadiene with –COOH terminals
CAS No. 69102-90-5 (general)
Molecular Weight (Mn) 1,000–5,000 g/mol (typical)
Functionality (COOH groups) 1.8–2.2 per molecule
Viscosity (25°C) 5,000–50,000 cP (varies with MW)
Density ~0.89–0.92 g/cm³
Acid Value 30–60 mg KOH/g
Glass Transition Temp. (Tg) -70°C to -50°C (high flexibility)
Solubility Soluble in toluene, THF, esters; insoluble in water
Curing Mechanism Reacts with epoxy, aziridine, or isocyanates


Key Features

  1. Elastic & Flexible – Low Tg ensures durability in extreme temperatures.
  2. Reactive Terminals – Forms strong bonds with epoxies, metals, and other polymers.
  3. Chemical Resistance – Stable against fuels, oils, and solvents.
  4. High Adhesion – Bonds well to metals, composites, and elastomers.
  5. Low Volatility – Minimal outgassing, suitable for aerospace applications.


Applications

1. Rocket Propellants & Explosives

  • Binder in solid fuels (e.g., composite modified double-base propellants).
  • Improves mechanical strength and elasticity.

2. Adhesives & Sealants

  • Aerospace adhesives (metal-to-composite bonding).
  • Automotive sealants (fuel-resistant coatings).

3. Coatings & Encapsulants

  • Corrosion-resistant coatings for pipelines.
  • Potting compounds for electronics.

4. Polymer Modification

  • Toughening agent for epoxy resins.
  • Compatibilizer in rubber blends.

Formulation & Curing

  • Epoxy-CTPB Systems: Enhanced impact resistance (used in aerospace).
  • Isocyanate Curing: Forms polyurethane-like networks (flexible sealants).
  • Aziridine Crosslinking: Fast-curing adhesives.
