Flame Defense Series

Antimony Trioxide 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.

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

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 between 30 and 50% of Antimony Trioxide. SDS

FD440 An antimony free inorganic synergist for halogenated flame retardant systems. 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. SDS

FDAO 100% antimony trioxide synergist for halogenated flame retardant systems. SDS

Other Flame Defense products available on request for specific applications.


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

SDAOM 100% Ammonium Octamolybdate smoke suppressant. SDS

Flame & Smoke Defense Series

Where a combination of smoke suppression and flame retardance is required in one product, MAT offers a range of single chemical zinc based products
as well as an emerging family of propritary reactive blends of zinc chemicals and other ingredients.

FSD479 is an antimony free proprietary inorganic blend flame retardant synergist for use with halogen based flame retardant polymer compounds where Zinc Hydroxy Stannate is used as the primary synergist. It allows the formulator to reduce the amount of the expensive Zinc Hydroxy Stannate while retaining flammability performance and hence provide an overall cost saving. This product is applicable to PVC, CPE, and a wide range of polymer systems where the flame retardant is bromine or chlorine based. SDS

CTZB400 Zinc Borate is typically used as a formulating additive to increase char strength, reduce smoke, and to provide afterglow suppression. SDS

CTZST Zinc Stannate combines smoke suppression and flame retardant synergy with halogenated flame retardants where antimony trioxide is not desired or permitted. It is suitable for formulations that are processed above 200°C. SDS

CTZHS Zinc Hydroxy Stannate combines smoke suppression and synergism with halogenated flame retardants where antimony trioxide is not desired or permitted. It is suitable for formulations that are processed below 200°C. SDS


Metal Hydrate Series

MAT offers a broad line of metal hydrate FR products. These include alumina trihydrate (ATH), a huntite / hydromagnesite blend, and magnesium hydroxide (MDH).

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.

HT900 Precipitated 0.9 micron d50 SDS    ¦    HT1000 Precipitated 1.4 micron d50 SDS    ¦    A202 Ground 2.0 micron d50 SDS    ¦    A204 Ground 4.0 micron d50 SDS

Additional grades of ATH are available. Please see our separate ATH literature or contact us for more information.

Huntite / Hydromagnesite Blend

HTMC9 is 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 Magnapur series of products are suitable for a wide range of demanding flame-retardant polymeric applications. Endothermic decomposition begins at about 330oC 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.

While Magnapur has good dispersibility in many resin systems, further improvements can be gained by using one of our coated grades. These coatings are selected for excellent compatibilityin 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.
