Antimony Trioxide (AO) and our AO replacement synergists enhance the flame retardancy of chlorine and bromine based chemicals and polymers.
The mechanism works in the vapor phase by capturing the free radicals generated by the combustion process.

Partial Replacements
FD440 An antimony free inorganic synergist for halogenated flame retardant systems offering maximum cost savings. FD440 can allow the formulator to significantly reduce the antimony trioxide level in a formula while providing equivalent performance at a reduced cost. This product is applicable to PVC, CPE, and a wide range of polymer systems where the flame retardant is bromine or chlorine based. Depending on the specific formulation it is typically possible to replace 50% of Antimony Trioxide. SDS
FD409 A reactive synergist blend specially formulated to provide a good balance of flame retardant performance and reduced cost when used as a partial Antimony Trioxide replacement. This product is applicable to PVC, CPE, and a wide range of polymer systems where the flame retardant is bromine or chlorine based. Depending on the specific formulation, it is typically possible to replace 50% of Antimony Trioxide. SDS
FD335 A reactive synergist blend specially formulated to provide the maximum flame retardant performance when used as an Antimony Trioxide replacement. This product is applicable to PVC, CPE, and a wide range of polymer systems where the flame retardant is bromine or chlorine based. Depending on the specific formulation, it is typically possible to replace between 50 and 100% of Antimony Trioxide. SDS
FDVW1 Specifically optimized for the cross-linked low voltage XLPE and EPDM wire & cable market. Within a segment of this market are wires and cables designed to meet the demanding VW1 flame test requirement. To achieve this performance, it is common to formulate with brominated flame retardants and Antimony Trioxide synergists. SDS
Leveraging The R.J. Marshall’s long history with Antimony Trioxide replacement products for PVC applications, a research program was undertaken to design a specific product for the VW1 application and similar systems where brominated flame retardants are used. FDVW1 is the result of those efforts.
To demonstrate the basic efficacy of the product, a typical polyethylene recipe was constructed, compounded, press-molded and finally cross-linked using electron beam irradiation for convenience. After confirming cross-link density, UL94 sample bars were cut (0.03 inches thick) and laminated to a thin copper sheet (0.02 inches thick) to provide the heat sink effect and structural stability similar to that encountered in an extruded wire.
The laminated UL94 samples were then tested using the basic UL94 protocol but adapted to simulate the VW1 test. Specifically, the flame was applied at a 20 degree from the vertical angle for 15 seconds for a total of 5 applications. The recipes evaluated and result obtained are shown here.
FDPE94 Provides formulators of UL94 rated polyethylene compounds with options to reduce the cost of their flame retardant package. Designed specifically for formulations flame retarded with halogenated additives, the cost-efficient FDPE94 product can replace over 50% of the Antimony Trioxide synergist, while maintaining flammability performance. Additionally, FDPE94 has been observed to reduce the flow and dripping of the material during UL94 testing when compared to an equivalent version which incorporates only Antimony Trioxide as the synergist.

FDPP94 Provides formulators of UL94 rated polypropylene compounds with options to reduce the cost of their flame retardant package. Designed specifically for formulations flame retarded with halogenated additives, the cost-efficient FDPP94 product can replace around 50% of the Antimony Trioxide synergist, while maintaining flammability performance. Additionally, FDPP94 has been observed to reduce the flow and dripping of the material during UL94 testing when compared to an equivalent version which incorporates only Antimony Trioxide as the synergist.
