Material Notes:
HJ320MO is a polypropylene homopolymer intended for injection molding. Its very high melt flow makes it especially suitable for thin-wall packaging and products with long flow length. This grade is characterized by the unique combination of very high flow, excellent stiffness and excellent organoleptic properties. This grade is designed for high-speed injection molding and contains nucleating and antistatic additives. Components molded from this grade show good ejectability and combine excellent stiffness with good transparency and gloss, very good color, excellent organoleptic properties and good impact strength at ambient temperatures. Applications: thin wall containers, closures, and products with thicker wall sections requiring short cycle time.Information provided by Borealis AG
