Rebuilding the Properties of Recycled Polyolefins
Bridging the performance gap between virgin and recycled Polypropylene (PP) and Polyethylene (PE) with advanced organic peroxide technologies.
La sfida
Legenda 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.
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.
Inferior Prestazioni 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.
Inconsistent Miscela & Broad Peso molecolare Distribution
PCR streams are heterogeneous mixtures of different polymer grades, contaminants, and degradation products, resulting in unpredictable processing behavior and final product quality.
Il nostro Solution
Perossido organico-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. Il nostro 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
Perossidi organici for Controlled Rheology Polypropylene (CR-PP)
Il nostro specialized organic peroxide grades are engineered for the reactive extrusion of recycled polypropylene. They enable precise, predictable reduction of molecular weight and narrowing of molecular weight distribution, producing controlled-rheology PP with consistent MFI and improved processing characteristics.
Whether you need to adjust MFI from low-flow to high-flow grades or stabilize inconsistent PCR feedstocks, our peroxide solutions deliver reliable, repeatable results at industrial scale.
