Polymeric halogen-free flame retardant. Halogen-free flame retardant composed of DPMP polymers is synthesized in a solventless reaction that only produces phenol as a major byproduct. This phenol can be used to produce more DPMP. Compared to traditional FRs, this product has superior performance and eliminates environmental and health risks. Traditional FRs are halogenated, enabling hazardous materials to migrate to the exterior of plastics and increase human exposure through contact. 60% of plastic formulations contained halogenated FR. This product is halogen-free, eliminating compound migration and halogen toxicity. The synthesis of the polymer also has around a 100% yield, making the production economically advantageous. Since this FR can be used in multiple materials without interfering with the materials' physical properties, this product can potentially increase recycling.
