Sappi Symbio PP40EF

Technical Datasheet | Supplied by Sappi
Sappi Symbio PP40EF by Sappi is a low density, polypropylene reinforced with cellulose fiber (40%). It offers good sound/damping, soft & warm touch, good processability, very good heat resistance and good aesthetics. Also, provides low water absorption and excellent scratch resistance. This thermoplastic composite contains renewable content and can be recycled or burned for energy. This grade is specially suitable for food contact applications. Sappi Symbio PP40EF consists of virgin polypropylene and specifically selected & treated wood-based cellulose from responsibly managed forests. It experiences very good flowability and is therefore ideal for thin wall applications. Due to its good balance between density, stiffness and impact resistance it can be used for a variety of applications. It can be processed by injection molding. It is suitable for recycling methods such as shredding, re-grinding and cleaning. This grade is used in automotive interior, consumer electronics, furniture, appliances and consumer goods.
