As safety legislation becomes evermore stringent across all aspects of construction and mass transportation; the ability to certify related products to fire and smoke standards becomes an increasing challenge to formulators. What’s more, the science behind controlling such factors using environmentally friendly technologies, is a complex field and linked to multitude of often connected variables. Combining resources our companies have worked closely with industry leaders and global producers to develop a range of synergistically functioning fire and smoke suppressing chemicals.


Through the combined effect of oxygen displacement, insulating char formation and heat absorption – our halogen free endothermic materials have mechanism to control ignition, fire spread, containment and after-burn in resin, polymer and elastomer products. No one solution fits all, but our diverse product portfolio allows us to tailor solutions to product specific requirements whilst accommodate a range of manufacturing processes. Moreover, our continued commitment to building upon product knowledge, promotes informed customer decision making.

Aluminium Hydroxide

One of the most widely used halogen free flame retardants, ATH can be applied at high loadings to achieve the desired properties. Through its endothermic decomposition into Aluminium Oxide and Water, it promotes heat absorption, char formation and o+J5xygen displacement at temperatures of around 200oC. We offer both precipitated and ground grades in abundance of colours and particle sizes – including a range of low oil absorption and black spec controlled products, promoting excellent strength, processing and colour in plastics.`

Ammonium Polyphosphate

At elevated temperatures, APP provides an essential source of polyphosphoric acid, necessary for char formation in intumescent systems. Available in two phases – an indication of the polymerization degree and the corresponding decomposition temperature – we can provide products suited to a wide range of processing temperatures. Our products range from 20 – 35 microns, with Silane, Melamine and Epoxy coated additions also available.


High purity Dicyandiamide is used as a spumific in intumescent systems. Commonly used alongside Ammonium Polyphosphate.

Magnesium Hydroxide

The decomposition of MDH at 300oC, makes it an ideal flame retardant in products processed at temperatures exceeding the activation temperature of ATH (200oC). In a similar fashion it releases water, absorbs thermal energy, whilst also presents good smoke reducing capabilities. Across our portfolios we can offer fine natural MDH alongside new coated variants.

Zinc Borate

A white, Boron based chemical, Zinc Borate is known for its synergy with a range of fire retardant chemicals, including ATH and Antimony Trioxide. Upon thermal decomposition it releases a crystal hydrate and water – absorbing thermal energy, preventing uptake of oxygen, reducing the drip effect, and limiting the release of toxic particulates – all through the formation of a glass like char on the polymer surface. Primarily however, Zinc Borate has found an important position in industry reducing afterglow effects. We offer high purity products, in a range of particle sizes, and surface treatments.
