NTR-971

NTR-971 is an newly developed catalyst by Shanghai Nartrin Chemical Company and commercially produced by Shanghai Leader Catalyst Company.  

This catalyst is specifically designed for applications in Loop Slurry Process for producing very broad molecular weight distribution (VBMWD) linear HDPE resins

In comparison with the conventional catalyst imported,NTR-971 has very similar catalyst activity, comonomer activity, and process compatibility.  

NTR-971 offers equal or higher melt index (MI) potential than the conventional catalyst imported under the same activation and polymerization conditions.  

So, from the process control viewpoint, NTR-971 offers the commercial PE plants an opportunity to operate at either slightly lower reactor temperatures or at somewhat higher ethylene pressures for making the same HDPE grade resins.  

The resulting HDPE resins offer better melt processibility and similar physical properties.  

At the same MI, NTR-971 PE resins typically exhibit higher melt strength at low shear and lower apparent melt viscosity at high processing rates than the conventional catalyst imported.  

These attributes imply that NTR-971 HDPE resins are better pipe, film, and large-part blow molding resins.  the NTR-971 resins are relatively free of long chain branching, and thus are better suited for HMW PE film applications.
