Aluminum Composite Panels (ACP) - the building facing composite material. The panels consist of two pre-painted aluminum sheets, between which is placed a middle layer - the polymer composition based on polyolefins.
Aluminum Non-combustible Panels consist of two aluminum sheets and filled polymer composite. The middle layer consists essentially of low density polyethylene and special flame retardant additives. This material is non-toxic because it contains no halogens and heavy metals (e.g. antimony). Especially for this application, the company has developed a product Ecopiren® 10.
Below you can see a table of comparison ATH with MDH.

Aluminum Trihydrate, Al(OH)3
180°C
1100 J/g
Magnesium Hydroxide, Mg(OH)2
330°C
1250 J/g
A large part of energy of decomposition expressed in a stronger cooling of composition or polymer base in condition of pyrolysis or combustion. High decomposition temperature means that in the formulations containing Ecopiren® higher processing temperatures can be used in comparison with ATH. This is a great advantage of the process meaning manufacturing costs savings for the ACP producer.
