Ecopiren in PVC wire and cable formulations
PVC is one of the most commonly used polymers worldwide. Although PVC already has a certain level of intrinsic flame retardancy, due to high flammability of added plasticizers it is still necessary to add flame retardants to meet most international fire standards. Examples are low voltage cable applications and wire insulations.
All Ecopiren products are perfectly compatible with PVC. An advantage of magnesium hydroxide when compared to ATH is its higher decomposition temperature and its greater heat absorption. See the table below for some comparisons.
|Product||Decomposition Temperature||Energy of Decomposition|
|Aluminum Trihydrate or ATH||190°C||1100 J/g|
|Magnesium Hydroxide or Ecopiren Mg(OH)2||330°C||1250 J/g|
Large energy of decomposition expressed in a stronger cooling composition or polymer base in the conditions of pyrolysis or combustion. The 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 cost savings for the cable producer.
