Applications of Recycled Polyethylene Terephthalate in Alloys, Blends and Compounds

6 Applications of Recycled Polyethylene Terephthalate in Alloys, Blends and Compounds 

In 1996,20 million lbs of rPET was used in applications in which it was first combined with another resin. This process, known as alloying or compounding, greatly increases the chemical resistance, dimensional stability and abrasion resistance. PET, both rPET and vPET, cannot easily be injection moulded PET will randomly crystallise during normal thick wall moulding thus making the moulded part brittle and subject to warp. The process of adding an impact modifier to PET allows it to overcome these problems and enables it to be used in other applications. 

Applications for these resins are in the industrial, lawn and garden, sports goods, electrical/electronic and automotive areas. Product applications include  

Alloying PET and PE doesn t make economic sense if you start with vPET, but it pays off as a use for inexpensive waste streams like coloured PET and barrier PET film scrap, which normally only find low-value applications or are thrown away. Combining PET and PE can yield unusual properties. The alloys are less brittle than 

Delleve reported single-wall PET/PE pipes of 75 mm diameter which showed an average initial stiffness of 5.678 kN/m this would allow the PET/PE pipe to be
