NTR-457WP is an new type chromium-based catalyst which is  a co-gel catalyst. It was designed for pipe &extrusion HDPE applications. It runs well in slurry loop process, yielding high activity,superior melt index potential, good comonomer incorporation, and high production rates.  

This high molecular weight, ethylene—hexene copolymer is tailored for only client especially. The resin grade is used in conduit  and corrugated pipe applications that require:

          *Excellent pipe stiffness

          *Outstanding slow crack growth resistance

          *Durability 

          *Superior melt strength

The polymers produced are excellent for pipe& extrusion applications, typical pipe application include:

          *Corrugated  installations for:

               •Roadway culverts

               •Storm sewers

               •Land drainage

          *Conduit  installations for:

               •Telecommunication

               •Data transmission

               •Electric
