PP – Polypropylene


PP FOAM is produced via the foaming method, which decreases the material’s density, rendering it considerably lighter than standard PP-H plastic. The method has only a minor impact on the material’s rigidity. The product’s elastic modulus (1,100 MPa) indicates its resistance to being deformed elastically. The closed cell structure prevents absorption of water, making the material suitable for wet conditions. This temperature range for this material in use is 0 °C to 100 °C. Its surface is smooth and shiny. We deliver PP FOAM as plastic sheets.
