| HF955MO is a very stiff polypropylene homopolymer. This grade combines unique Borstar reactor design with Borealis Nucleation Technology (BNT) to produce highly-crystalline polypropylene. This combination also results in unique balance of properties especially suited for high-speed injection moulding. Products originating from this grade have excellent demoulding properties, very high stiffness, good transparency and gloss and good impact strength at ambient temperatures. CAS-No.: 9003-07-0 Applications Caps and closures Rectangular and flat products, like lids and trays Products with thicker wall sections requiring short cycle time Containers and products with medium to long flow length Special features Good stiffness Improved gloss and excellent transparency Good impact strength&& |
