Flaming Retardants

Flame retardants include a variety of substances added to flammable materials to either prevent fires or slow their spread, offering additional time for safe evacuation. Among the common flame retardants are TCPP and TEP.

Arpadis, one of Europe’s largest chemical distributors, manages the storage, transportation, and global import/export of these flame retardants.

TCPP (CAS: 13674-87-8)

Tris (1-chloro-2-propyl) phosphate is an additive flame retardant widely used in PU foams for consumer products, home insulation, and electronics. This colorless, stable liquid is non-volatile at room temperature and is synthesized by reacting 1-chloro-2-propanol with phosphoryl chloride in the presence of a catalyst.

TEP (CAS: 78-40-0)

Triethyl phosphate is versatile, used not only in PU foams but also as a viscosity reducer in certain polyols and prepolymers. TEP can be manufactured either by reacting phosphoryl chloride with ethanol or through oxidation of triethyl phosphite.

Flame retardants generally exhibit low acute toxicity via oral, dermal, or inhalation exposure, with minimal skin and eye irritation and no genetic activity.
