Stabilizing rPET Performance, Maximizing Circularity
Introducing the next-generation additive designed to prevent PET degradation during the recycling process
PET Recycling Challenges
Recycled PET (rPET) plays an essential role in the shift toward a circular economy, but repeated recycling cycles introduce material performance challenges. With each cycle, rPET deteriorates, resulting in loss of mechanical integrity and coloristic performance, and limiting its use in food-contact applications.
To address these challenges and improve the quality of recycled PET, CircStab offers advanced stabilization during the recycling process. It enhances material quality, improves recyclability and preserves the structural integrity of rPET for future applications.
How Circstab® works
CircStab is a next-generation additive designed to prevent PET degradation during the recycling process. By stabilizing rPET, CircStab ensures excellent optical and mechanical properties, maintaining key performance parameters such as:
- L* - Preserves brightness for high-quality, clear rPET
- b* - Minimizes yellowing for better color consistency
- AA (Acetaldehyde) Levels - Reduced to further ensure safe and high-purity applications
- IV (Intrinsic Viscosity) - Prevents molecular degradation, boosting rPET strength and durability.
The benefits
-
- Enhancing Aesthetics - Enabling Brighter, clearer rPET
- Minimizing Toners - Reduces dependence on color neutralization toners, effectively increasing L* values
- Retaining Mechanical Properties - Retains strength and flexibility over multiple recycling cycles
- Optimizing Processing Efficiency - Optimizes industrial-scale PET recycling, significantly reducing SSP times and increasing line throughput
- Sustainability Boost - Supports a circular economy by increasing the quality and re-usability of rPET
- Regulatory Compliance - Meets stringent industry regulations, ensuring safe and compliant use in PET recycling
- Advanced Dosing Solutions - Allows precise and efficient additive integration and gives recyclers peace of mind
