Flame‑Retardant Modified PET Plastic

PET flame‑retardant modification can be realized through copolymerization, blending, fiber finishing and other technical routes. Modern flame‑retardant technologies pursue halogen‑free and eco‑friendly directions. For instance, PET fibers modified with sodium copper chlorophyllin (biomass‑based dyestuff) and phosphorylated sucrose fatty‑acid esters achieve high‑efficiency flame‑retardancy and anti‑dripping performance. The modification promotes dense graphitized char‑layer formation upon combustion, isolating oxygen and heat, meanwhile releasing non‑flammable gas to dilute combustible‑gas concentration. Modified‑PET exhibits obviously increased limiting‑oxygen‑index, its peak heat‑release rate drops by over 40 %, and it features self‑extinguishing after flame removal with effective suppression of molten dripping.

Main Applications

Electronics & Electrical Appliances: Halogen‑free flame‑retardant reinforced‑PET grades with high glow‑wire ignition temperature and high comparative‑tracking index are widely used for safety‑critical components including frequency‑converter bobbins, relays and wiring terminals.

Textile Industry: Flame‑retardant anti‑dripping PET fibers are processed into special work‑clothes, home‑textile products and interior fabrics for transportation vehicles, greatly improving safety during wearing and service.

Properties: flame‑retardant Physical properties: customizable per customer requirements (partial performances can match imported brands).

MOQ: 1 ton upon successful sample testing.
