The products of the cable, rubber and thermoplastic industries must be safe in case of fire so that people can leave the danger zone before a fire spreads.

For this purpose, the ALFRIMAL® product range was developed, which – depending on the specific surface of the material – can release its water bound in the crystal at different rates: either as a water booster or evenly over a longer period of time to keep escape routes free from fire spread for as long as possible.

As a halogen-free, flame-retardant active ingredient, ALFRIMAL® reacts immediately to the temperature increase that occurs in the event of a fire and has a smoke-retardant effect without affecting the processing of materials in terms of their colour, surface or grip and is therefore available and applicable for all market requirements in a wide variety of areas.

Highly white, halogen-free ATH-based flame retardant for solid surfaces – without black spots – optimum physical filler properties result in excellent chemical resistance and dirt repellency from the product surface. Thanks to its hydrophobic, special coating, the new product ALFRIMAL® 549 XS HS shows the best physical properties and a reduction in viscosity. With its excellent chemical resistance, it makes media-resistant surfaces of mineral materials dirt-repellent and it`s “hard” enough to ensure excellent impact resistance, but at the same time “soft” enough to enable wear-free, rapid processing and not have a negative impact on the service life of machine parts.

 

ALFRIMAL® –  How does flame retardancy work in the product ?

ALFRIMAL®, based on aluminium hydroxide, has a flame-retardant effect by releasing one third of its weight as water at an ambient temperature of approx. 200 °C and above.
1. this reaction is endothermic and cools down the source of the fire.
2. the water prevents the oxygen in the ambient air from reaching the flammable gases produced by the pyrolysis.
3. the aluminium oxide remains on the surface of the solid as an inert protective layer.
