Polymer Recycling & Modification

Rebuilding the Properties of Recycled Polyolefins

Bridging the performance gap between virgin and recycled Polypropylene (PP) and Polyethylene (PE) with advanced organic peroxide technologies.

Polymer recycling applications

Chìa khóa Barriers in Post-Consumer Recycled (PCR) Polyolefins

Recycled polyolefins face three fundamental obstacles that limit their re-introduction into high-value applications. Understanding these challenges is the first step toward effective solutions.

01

Limited & Inconsistent MFI Range

Post-consumer recycled polyolefins exhibit a wide and often unsuitable Melt Flow Index (MFI) range, making consistent processing in injection molding and extrusion applications extremely challenging.

02

Inferior Hiệu suất vs. Virgin Material

Recycled PP and PE typically show reduced mechanical properties — lower tensile strength, impact resistance, and thermal stability — compared to their virgin counterparts, restricting end-use applications.

03

Inconsistent Trộn & Broad Trọng lượng phân tử Distribution

PCR streams are heterogeneous mixtures of different polymer grades, contaminants, and degradation products, resulting in unpredictable processing behavior and final product quality.

Organic peroxide chain modification for recycled polyolefins

Peroxide hữu cơ-Based Chain Modification for Recycled Polyolefins

At Do Sender Chem, we provide advanced organic peroxide solutions that enable precise control over the molecular structure and rheological properties of recycled polyolefins. Của chúng tôi controlled-rheology peroxides initiate selective chain scission and branching reactions, tailoring the MFI, molecular weight distribution, and mechanical properties of PCR materials.

By applying our organic peroxide technology, recyclers and compounders can transform inconsistent, low-value PCR streams into high-performance materials suitable for demanding applications — effectively closing the gap between recycled and virgin polyolefins.

  • Precise MFI adjustment through controlled degradation
  • Improved mechanical properties and processability
  • Consistent batch-to-batch quality for industrial applications
  • Enables higher PCR content in finished products
