RECYCLOBYK® 4376

RECYCLOBYK® 4376 by BYK is a granulated stabilizer concentrate to improve the mechanical and rheological properties for the recycling of engineering plastics including recycled polyester and polyamide polymers. It re-stabilizes against the negative influences of hydrolytic degradation and enhances long-term thermal stability.

• It is used for increasing the resin viscosity of degraded post-consumer PET flakes.
• It improves the processing and the properties of recycled polycarbonate, PET, PBT, TPU.
• It increases melt strength of polycondensation polymers and allows the processor to reduce material costs by incorporating a higher content of regenerate/recyclate into the polymer compounds.
• It is easily dispersed into the resin by using conventional extrusion compounding techniques.
• Recommended dosage level is 0.1-0.7%.
• Shelf life of RECYCLOBYK® 4376 is 24 months.
