Introducing Our High-Efficiency Flame Retardant DOPO
As a premier manufacturer and supplier in China, we offer DOPO (CAS No. 35948-25-5), a critical component for achieving superior fire safety in polymer materials. Our DOPO is a white, flake-form flame retardant with a unique phosphorus-containing heterocyclic structure. It provides excellent thermal stability, decomposing above 300°C, and integrates covalently into epoxy matrices, preventing migration and ensuring long-lasting performance. We are a reliable supplier committed to quality and competitive pricing for your procurement needs.
- Achieve UL94 V-0 Rating: Our DOPO enables UL94 V-0 compliance at low loading levels (3-5%), crucial for electronic applications.
- Reactive Flame Retardancy: Its reactive functionality allows chemical incorporation into epoxy networks, modifying curing behavior and enhancing material properties.
- Superior Thermal and Electrical Properties: DOPO enhances char formation, reduces heat release, and maintains excellent dielectric characteristics vital for electronic components.
- Environmentally Compliant: As a halogen-free solution, DOPO meets stringent RoHS and REACH requirements, offering a safer alternative to brominated flame retardants.
