Plasticizer – Flame Retardant

Phosphate‑based flame‑retardant plasticizers for PVC/plastisols, cables, foams and adhesives. Options include non‑halogenated aryl/alkoxy phosphates and chlorinated phosphate esters. Low‑fog, high‑Tg and viscosity‑tuned blends available.

Compliance & application notes.
  • Chlorinated phosphate esters: TCEP and TDCPP are restricted/banned in many regions and end‑uses. TCPP use in foams/wires may be limited—confirm local rules.
  • Electronics/building: non‑halogenated aryl phosphates (TPP/IPPP/RDP/BDP) are often preferred for lower smoke/corrosivity; verify UL‑94, LOI and RoHS needs.
  • Processing: viscosity and plasticizer permanence trade off with flame performance; blends can tune fusion time vs. fogging and cold‑flex.

Aryl Phosphates

Non‑halogenated • lower smoke

Alkyl/Alkoxy Phosphates

High permanence • good plasticization

Chlorinated Phosphate Esters

High FR efficiency • compliance varies

Non‑halogenated FR Oligomers

DOPO‑based • low migration

Performance Blends

Tuned viscosity, fusion & FR

Specialty & Low‑Fog

Automotive interior • low VOC
