Flame Defense Series
Antimony Trioxide (AO) and our AO replacement synergists enhance the flame retardancy of chlorine and bromine based chemicals and polymers.

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.

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. SDS
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.

Smoke Defense Series
Ammonium Octamolybdate (AOM) is a well known additive for smoke suppression in plasticized PVC.
Based on this technology, MAT has developed a high performance, low cost, reactive blend that can improve upon the performance of AOM alone.

SD890 A reactive smoke suppressant blend specially formulated to provide the maximum reduction in smoke generation at the lowest possible cost when replacing molybdate based additives in PVC compounds. Specifically, work has been done which shows that it is possible to replace 100% of Ammonium Octamolybdate while achieving a further improvement in smoke suppression of a typical PVC plenum jacketing formulation and small gain in flame retardancy. SDS
SDZAM A reactive smoke suppressant blend that has been specifically formulated to provide a more cost effective alternative to Zinc Molybdate coated Talc (ZMT) products in the market for application in PVC compounds. Our experimental work has shown that SDZAM can be used as a direct replacement for ZMT type products and deliver similar smoke suppression performance together with a gain in the Limiting Oxygen Index of the PVC compound.

Metal Hydrate Series
Where a halogen-free solution is needed alumina trihydrate (ATH), magnesium hydroxide (MDH), and huntite/hydromagnesite can be used. MAT offers a range of ATH and MDH grades and a huntite/hydromagnesite blend. These products are typically selected for halogen free applications and work according to two modes. Release of water and endothermic decomposition. The water release reduces the temperature in the combustion zone, excludes oxygen and combines with soot particles to reduce smoke. The endothermic nature of the decomposition removes heat energy from the combustion process.
An important property in selecting a metal hydrate is:
Alumina Tryhydrate
Alumina Trihydrate is the most widely used flame retardant in the world due to its versatility and low cost. Available in different particle sizes, it can be used in a wide range of polymers at processing temperatures below 220°C. ATH is non-toxic, halogen-free, chemically inert, and has low abrasiveness. Additional benefits are arc and track resistance in plastics exposed to electrical arcing, acid resistance, and smoke suppression. The non-toxic, zero halogen alumina trihydrate (ATH) is offered by MAT from a precipitated and fine grinding process.
HT1000 Precipitated 1.4 micron SDS ¦ A202 Ground 2.0 micron SDS ¦ A204 Ground 4.0 micron SDS
Additional grades of ATH are available. Please see our separate ATH literature HERE or contact us for more information.
Huntite / Hydromagnesite Blend
HTMC9 A white finely-divided combination of magnesium calcium carbonate (huntite) and hydrated magnesium carbonate. With thermal stability above that of ATH and low cost, it can be used as a replacement for magnesium hydroxide and can be used in halogenated systems as well. It can offer a cost/performance advantage over magnesium hydroxide and can allow higher processing temperature than ATH. SDS
Magnesium Hydroxide (Magnapur®)
The non-toxic, zero halogen Magnapur line includes both a very pure, synthetic, ultra fine Magnesium Hydroxide (MDH) and a pure, natural, fine MDH. The Magnapur series of products are suitable for a wide range of demanding flame-retardant polymeric applications. Endothermic decomposition begins at about 330°C releasing water, which produces a cooling effect, reduces oxygen availability and suppresses smoke evolution. The resulting Magnesium Oxide ash provides a char layer, which further reduces the combustion rate of the system. These combined mechanisms result in an overall powerful flame retardant performance which allows polymer formulators to design products to meet the most demanding specifications in wire & cable insulation and jacketing, sheet, film, and profile applications.
The relatively high decomposition temperature compared to other zero halogen fillers, such as Alumina Trihydrate, allows for a significantly higher processing temperature without the concern of developing porosity in the finished part.
Where improved dispersion is needed, one of our coated Magnapur grades can be used. These coatings are selected for excellent compatibility in a wide range of resins and to provide the opportunity for chemical coupling with the polymer matrix. This can result in significant increases in physical properties, extrusion smoothness and resistance to moisture.
