Technical Positioning

Sinotech’s PP catalyst platform is positioned around Ziegler-Natta catalyst systems used in polypropylene production. The focus is not only catalyst activity, but the full performance relationship between catalyst, TEAL, external donor, reactor condition, resin target, morphology, and operating response.

Product Architecture

PP-CAT 100

General Purpose

General PP production direction, including homopolymer, random and impact grades.

PP-CAT 200

Spherical / Low-Fines

Spherical catalyst positioning focused on morphology, bulk density and low-fines operation.

PP-CAT 500

Broad Grade Flexibility

Advanced grade-flexibility positioning for broader PP product requirements and consistent operating response.

Technical Control Matrix

AreaTechnical Control FocusIndustrial Relevance
ActivityCatalyst productivity and reaction stabilitySupports reactor throughput and process continuity
IsotacticityDonor response and stereoregularity controlInfluences stiffness, clarity and PP grade quality
MorphologyParticle shape, fines, bulk density and powder flowImproves handling and downstream processing
MFR ResponseHydrogen response across operating windowsSupports grade transition and resin targeting

How Selection Works

PP catalyst selection is reviewed against:

Reactor type Resin grade target Productivity expectation Morphology requirement Fines tolerance MFR target Hydrogen response Donor requirement TEAL compatibility Downstream powder handling Repeat supply requirement Pilot / customer trial feedback
