The MarTECH® Loop Slurry Process is CPChem's proprietary technology for producing high- and medium-density polyethylene. Introduced in 1961 and continuously advanced through catalyst and process innovation, it is a global benchmark for efficiency, reliability, and resin consistency across applications including rigid packaging, pipe, films, and coatings.
How It Works
Ethylene and comonomers polymerize under tightly controlled conditions in a loop slurry reactor, delivering consistent polymer structure and performance. Available in Single Loop (SL) and Advanced Dual Loop (ADL) configurations, the process uses proprietary catalysts and automated controls to achieve precise molecular weight distribution across product lines.
Why It Matters
Efficiency — Simplified reactor design cuts capital costs by ≈50% versus legacy systems.
Reliability — Demonstrated on-stream factors ≥98% deliver exceptional reliability.
Quality — Produces uniform, high-performance polyethylene grades for both rigid and flexible applications.
Innovation — Decades of process refinement and catalyst development make MarTECH® one of the most trusted technologies in global polymer manufacturing.
