Halogenated phosphate ester FRs for polyurethane foam, rigid PU, CASE, and coatings. SDS, TDS, TSCA compliance letters on request.
Chlorinated phosphate ester flame retardants for polyurethane foam, rigid PU, CASE systems, and coatings. Both grades supplied as clear liquids with SDS, TDS, and TSCA compliance letters on request. Contact us for pricing.
TCPP is the most widely used liquid flame retardant for polyurethane foam. It integrates into the foam matrix during the PU reaction, providing durable fire resistance without migration. Also used in rigid PU insulation, CASE adhesives and sealants, and industrial coatings where a reactive FR is required.
