Giving their mechanical properties and low manufacturing cost, thermoplastic multilayered materials have proven to be an adequate solution for such applications.
To meet this overall objective, the constituent materials (TPO and PP) and the multilayered sheet are characterized in a temperature range from the room temperature to 120°C.
