Manufacture and rheological behavior of all recycled PET/PP microfibrillar blends
For several years, new plastic bottles made from opaque polyethylene terephtalate (PET) have been on the market. When their waste is mixed to those of recycled clear PET, the obtained material cannot be recycled anymore due to a loss of properties. Moreover, because of an important grade variety, th...

| description | For several years, new plastic bottles made from opaque polyethylene terephtalate (PET) have been on the market. When their waste is mixed to those of recycled clear PET, the obtained material cannot be recycled anymore due to a loss of properties. Moreover, because of an important grade variety, the large number of additives used and poor homogeneity, the processing and recycling of opaque PET appears as a challenge. The way chosen to revalue this recycled opaque PET (r‐OPET) is its microfibrillation in a recycled polypropylene (rPP) matrix. The effects of the concentration of r‐OPET were studied by rheology, supported by scanning electron microscope images and related to the morphology of the mixture. It was demonstrated that (20/80)w r‐OPET/rPP blend was the best ratio to favor microfibrillation, as it offers the appropriate amount of solid filler to obtain a sea‐island morphology.
Thereafter, the influence of the temperature of microfibrillation is presented. The thermomechanical curve of the (20/80)w r‐OPET/rPP blend suggests that microfibrillation should be more effective around the Tg of r‐OPET. The optimum temperature was found, where an improvement of rheological and mechanical properties is observed. A Cross model with yield stress is proposed to describe the rheological behavior of this material.
Microfibrillation consists in the manufacture of micron scale fibers of a first polymer (recycled opaque polyethylene terephtalate) in a second one making up the matrix (rPP) to improve the properties. |
