Produced using the Global No.1 process that requires the lowest energy consumption and carbon emissions among PET recycling methods. Compared to the virgin process, it achieves an 86% reduction in Non-Renewable Energy Use (NREU) and a 76% reduction in Global Warming Potential (GWP) emissions.

Traditional halogen-based flame retardants are being restricted in various regulatory frameworks such as the European RoHS directive due to their adverse health effects, including dizziness, visual impairments, headaches, abdominal pain, disorientation, and hallucinations. There's a growing trend to replace these with non-halogenated products.

These flame retardants work by trapping active OH and H radicals with radical HX, leading to stabilization. HX is non-flammable and works by dilution and by blocking oxygen, thus manifesting its flame-retardant properties.

However, during injection molding, these substances can release gases, and during incineration, they can produce environmentally harmful dioxins. They are also associated with severe soot and smoke generation due to aromatic hydrocarbons.

In the gas and condensed phases, the simultaneous interaction leads to the manifestation of flame-retardant effects through the dehydration and carbonization caused by the thermal decomposition of phosphoric acid, as well as the scavenging of hydrogen and hydroxyl radicals by phosphorus-containing radicals.

Formation of char and phosphoric layers: During combustion, the formation of char is facilitated, creating an incombustible layer on the surface that physically obstructs the internal heat transfer within the polymer resin.

Flame retardant mechanism in the gas phase: Through pyrolysis, radicals such as PO2· are generated. This mechanism, similar to that of halogen-based flame retardants, captures hydrogen and hydroxyl radicals, forming a flame-retardant mechanism in the gas phase.
