PP1121 is a high impact polypropylene heterophasic copolymer intended for extruded goods.
This grade is characterized by combination of good stiffness, good creep resistance and very high impact strength even at low temperatures.
This grade features high thermal stability, very low shrinkage and very good processability. As all polypropylenes, this grade shows excellent stress-cracking and chemical resistances.
This grade is mildly nucleated to maximize the mechanical stiffness. Nucleation, good flow properties and high stiffness create a high potential for cycle time reduction.
Special Features
Good stiffness Good impact strength Good stress crack resistance Very good processability High melt stability Very low post extrusion shrinkage
