What is Dimethyl propylphosphonate?
Dimethyl propylphosphonate (CAS 18755-43-6) is an organophosphorus ester used in polymer and specialty chemical formulations as a flame retardant and plasticizing agent.
Where is Dimethyl propylphosphonate used?
- Plastics and polymer systems: incorporated into resins and coatings to impart flame retardancy while improving substrate flexibility
- Home care and industrial cleaning: functional solvent or co-solvent component supporting soil removal and formulation stability
- Specialty polymer synthesis: reactive intermediate or modifier
- Industrial coatings: compatible with a range of resin types for fire-resistance standards
- The phosphonate group can be integrated into the polymer backbone for durable flame retardant performance.
Commercial specifications
- Packaging: drums to IBC containers depending on order volume
