Ziegler-Natta Catalyst For Propylene Polymerization

Introduction:

C-2 is the 2nd  generation sorbitol based PP clarifying agent which gives excellent clarity, gloss and surface smoothness to the PP products.  It also improves physical properties of PP products, such as heat resistance, stiffness, moisture barrier etc.
Chemical Name:  (1,3:2,4)-diparamethylbenzylidene sorbitol (MDBS) CAS No.:  54686-97-4

 

Introduction
P-101 and P-201 are high performance catalysts for the production of polypropylene. The catalysts are Ti- Mg based, belonging to Ziegler-Natta 4th generation catalyst. The catalysts are developed and manufactured in China by China Catalyst Limited using the state-of-the-art technology.
P-101 and P-201 catalysts have excellent performance in propylene polymerization.  These catalysts are designed  for use in the Spheripol  technology.   They show low sensitivities  to impurities or poisons contained in the monomers, and thus offer  wide operating windows in the Spheripol processes.
P-101 and P-201 also give high activity and high stereoregularity.  The polymer particles have good morphology and low fines.
