Polyethylene Terephthalate - PET Fire Retardant

Polymer Type

Thermoplastic

Advantages

Low flammability and propagation rates compared with unmodified PET.

Disadvantages

Fire retardant additive is very susceptible to thermal degradation. If thermal degradation should occur, noxious fumes are produced. Regrind material should not be used.
