Aludecor FireWall having more than 71% mineral content is a tried and tested non-halogenated FR ACP that:
FireWall A2 is 90% halogen-free, inorganic material that produces water vapour when it heats up.FireWall has more than 71% mineral content. Both do not produce toxic gases like halogenated materials.
Magnesium hydroxide (MDH) is the non-halogenated material that is mixed with PE to form the core of Aludecor’s FR products. MDH has a better fire-resistance performance than aluminium trihydrate (ATH), the other non-halogenated material, owing to higher decomposition temperature. Furthermore, MDH is more environment-friendly than other similar materials.
MDH delays the PE transformation from solid to plastic (the point of ignition) up to 360°C, by releasing water molecules and bringing down the temperature continuously.
|Core Details||Polyethylene||Magnesium Hydroxide (MDH)||Aluminium Trihydrate (ATH)|
|Chemical reaction||CH2 + O2 = CO2 + H2O||Mg(OH)2 = MgO + H2O||2Al(OH)3 = Al2O3 + 3H2O|
|Decomposition temperature||90˚C to 110˚C||310˚C to 360˚C||190˚C to 240˚C|
|Status||Heat generation||Heat absorption||Heat absorption|
At Aludecor, the end-to-end production facility is foolproof and competes with global standards. The two production units spread over 25,000 sq. at Haridwar are equipped with up-to-date technology and testing facilities. The stringent quality control system keeps a sharp eye on each unit produced.
Aludecor ACPs can come in Aludecor FireWall A2 grade. Aludecor FireWall A2 has Factory Production Control certification from Exova Warringtonfire of the UK (ewcl5) for reaction to fire classifications of EN 13501-1 Class A2 – s1, d0. FireWall A2 is only available in AL45 grade.
Aludecor ACPs can come in Aludecor FireWall, Fire-Retardant grade. It has Factory Production Control certification from Exova Warringtonfire of the UK (ewcl5) for reaction to fire classifications of EN 13501-1 Class B– s1, d0, BS476, Part 6 and 7 Class O and passes resistance to fire for 2 hours in accordance with ASTM E119-12. Aludecor Firewall (Fire-Retardant grade) is available for a complete range of ACPs.
An FPC which underscores the validity of the production process followed in a factory is considered much more important and relevant compared to a simple test report received from testing organisations. The issue of an FPC involves thorough checking and testing at the factory concerned. In FPC both the product and the process employed to manufacture it are tested by agencies like Exova which have fire-testing labs.
The 1a certification for an Indian plant implies that a company is using the same category of machinery, not necessarily the same machinery, capable of producing a similar product. The product itself is not tested.
Aludecor is equipped with Baby Line, a miniature version of an ACP Lamination Line, for trial production of the Aludecor mineral core.
The mineral core produced in this Baby Line is subjected to rigorous tests, and only on clearing them, is the particular batch sent for final production.
Before going for the final production, each batch of the mineral core produced in the Baby Line is thoroughly tested.

Materials that catch fire easily are more ignitable, flammable or combustible. For example, the paper is more ignitable or flammable than wood. Various testing procedures can be treated as effective tools to quantify the capability of any material to resist fire. There are international protocols in place to determine the flammability or combustibility of different kinds of substances.
The EN13501-1 is an effective way to test combustibility of various materials.
The Limiting Oxygen Index is a measure of the percentage of oxygen that has to be present to support combustion of the plastic materials. The benchmark is 21%. Below this, the material will catch fire easily, but above it, the tendency will be reduced. The higher the LOI value, the higher the non-flammability.
Checks if light passes through the smoke produced or not so that it does not blur human vision. Smoke Density Index (SDI) helps to measure the concentration of smoke emitted by burning materials. Higher SDI rating means that the material emits a greater quantity of smoke, when burning, than low density rated materials. We know that smoke kills faster than fire and causes more fatality than heat. Smoke produces life-threatening toxic products and reduces visibility. It also hinders escape from a fire zone. It is important to keep in mind that ASTM D 2843 is an important method to measure the SDI rating of plastics.
