Enhance PCR-Engineered Resin with PARALOID™ Impact Modifiers
Many industries push toward circular economy initiatives and postconsumer recycled (PCR) plastics, manufacturers face challenges in maintaining impact strength, durability, and processability in recycled polymers due to processability and degradation difficulties. Dow’s PARALOID™ Impact Modifiers provide enhanced mechanical properties to PCR polycarbonate (PC), PC/ABS, PC/PET, and other engineered resins, ensuring high-performance recyclability without compromising quality.
Challenges in PCR Engineering Resins
While PCR plastics are crucial for sustainability, they often suffer from the following:
Reduced impact strength due to polymer degradation
Lower toughness and mechanical performance compared to virgin resins
Color inconsistencies and weathering challenges in outdoor applications
Multiple processing cycle instability, affecting long-term material integrity
PARALOID™ EXL Impact Modifiers address these issues by improving impact resistance, process stability, and durability in PCR formulations.
Key Benefits of PARALOID™ Impact Modifiers in PCR-Engineered Resins
Increased Impact Strength & Toughness
PCR polycarbonate and polycarbonate blends experience significant impact strength recovery when formulated with PARALOID™ Impact Modifiers. Studies show a 5x–20x improvement in notched Izod impact strength, depending on the quality and source of the PCR material.
