New: Upcycling plastics with Kraton innovation
The American company Kraton, headquartered in Houston, Texas, is now producing CirKular+™ – a range of additives that enhance the reusability and quality of mixed recyclable plastics in a wide variety of applications. Starting this autumn, Nordmann will begin distributing these new products in several European countries.
Mixed-plastics recycling streams with non-compatible materials and difficult-to-recycle engineering polymers are a challenge for the recycling industry. The inferior mechanical properties and poor processability of these streams often limit their reusability.
Wide range of applications
CirKular+™ Plastics Upcycling solutions from Nordmann’s partner Kraton create sustainable value for the various stakeholders in the value chain – from recyclers and compounders to converters and brand owners. Potential uses of CirKular+™ include compatibilization of post-consumer and industrial plastics recycling streams, the modification of bioplastics and flexible product design through a combination of virgin and recycled plastics.
The CirKular+™ Compatibilization series is available in three grades (C1000, C1010 and C1010 (50% recycled), enabling cost-efficient compatibilization of a wide range of contaminated post-consumer recycling streams – including PET, polyamides and ABS contaminants. The C2000 and C3000 series offers performance enhancement solutions for polyolefinic recycling streams (HDPE, PP, LDPE, polyolefinic blends and PS).
Even at low levels, the addition of CirKular+™ can improve the mixing and miscibility of incompatible resins and improve the processability of recyclates while delivering improved mechanical performance (e.g. better elasticity and up to 500% higher impact strength). Plastics modified with CirKular+™ show better reusability and can withstand up to five recycling cycles. The products demonstrate excellent processing versatility and can be used by converters through dry-blending in extrusion and injection molding, or in compounded applications to deliver cost-effective solutions. CirKular+™ grades are now available as samples.
