Material Notes:
1450N is a high heat resistance, easy flowing crystal polystyrene for the production of thick insulation board. The low viscosity of this grade makes it particularly suitable for the production of insulation board at high thickness (10-12 cm), combining low density with good mechanical properties. This grade is not lubricated.ApplicationThick insulation boardInformation provided provided by Total Petrochemicals.Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
