1.TCPP is a flame retardant of low hydrolytic stability, used in polyurethane (PU) rigid and flexible
foam, PVC, EVA and phenolics and epoxy resin.
The vast majority of TCPP is used in rigid polyurethane foams. It is also used in flexible
polyurethane foams for furniture and its upholstery, principally in the United Kingdom and Ireland .
TCPP is added at various points in the polyurethane supply chain:to final foam producers; to
"system houses" who pre-blend and formulate ready-made systems; and to base polyol producers who may use it to reduce polyol viscosity/mobility.
The use in rigid polyurethane foams may be further sub-divided into blocks and spray systems for building insulation and for refrigerator casings. Very small
use of TCPP also exists in textile back-coating formulations and in certain coatings.
2.Property and usage:
Soluble in benzene, alcohol, ester and other organic solvent, not soluble in
water. It is an additional flame retardant with excellent flame resistance due to the synergia of
phosphor and chlorine. Meanwhile it has the merits of plasticizing, moisture-proof and anti-static. It is widely used in PVC, PU, EP , UPR, PF PST, , rubbers and coating.
3.Package, transportation and storage
