PET means polyethylene terephthalate. It is part of the polyester family and the most common thermoplastic polymer. Beside its numerous uses, the transparent, light plastic, especially as classic PET bottle, turned part and parcel of our daily life.
However, the production of PET based on petrochemicals is problematic. The production of 1 kg PET requires approx. 1.9 kg crude oil. However given the fact of rising piles of rubbish, recycling has been established worldwide as an ecological and energy-saving production form.
RUDOLF GROUP devoted itself to steadily improve the PET recycling process with innovative, ecological products.
All these process steps are perfected by products of RUDOLF GROUP
Presorting of plastic according to colours and the removal of impurities (e.g. metal springs etc.) is realised
The material is shredded to flakes, coarse dirt is removed during usually cold prewashing and then, completely cleaned in a hot and intensive washing cycle.
By means of sink-float separation, the clean material is separated from caps and labels made of polyolefines (polyethylene or polypropylene) due to differences in density.
RUCOGEN® RPD is a universally applicable, low-foaming detergent, which is excellently suitable for cleaning PET flakes.
RUSTOL® RPA is a modified silicone defoamer, especially developed for plastic recycling processes and especially suitable for machines with high liquor turbulence.
RUCO®-FLOC RPF is an additive and defoamer for sink-float separation within plastic recycling processes.
