Flame‑Retardant‑Modified PS Plastic

PS consists of carbon and hydrogen elements. It is highly flammable and generates burning drips, making flame‑retardant modification indispensable. Modern modification technologies pursue halogen‑free and eco‑friendly solutions. Intumescent flame‑retardant systems such as compounded ammonium polyphosphate (APP) and expanded graphite (EG) are commonly compounded into PS matrix. Upon combustion, APP catalyzes char‑formation while EG expands rapidly. Together they build dense porous char layers for heat‑insulation and oxygen‑barrier purposes, realizing flame‑retardancy and suppressing smoke emission and molten dripping. Nitrogen‑containing flame retardants or silicon‑based flame‑retardant agents can also be adopted for modification.

Main Applications

Flame‑retardant modified PS is widely adopted in fields with strict fire‑safety requirements, including electronics and electrical appliances (TV housings, monitors, chargers and junction boxes), building thermal‑insulation materials, rail‑transit and automotive interior trim parts. Halogen‑free flame‑retardant PS is particularly suitable for electronic products exported to the EU and other regions with high environmental standards.
