Kraton’s CirKular+ C2000 & C3000 resins approved by RecyClass
09 Mar 2022
Results of an independent laboratory testing demonstrate that the resins ‘CirKular+ C2000’ & ‘C3000’ developed by Kraton Polymers are fully compatible with the rigid HDPE and PP recycling streams.
‘CirKular+ C2000’ & ‘C3000’ technologies act as compatibilizers or impact modifiers within polyolefin matrixes. Both resins are Styrenic Block Copolymers (SBC) based on poly(ethylene-co-butylene) and polybutadiene respectively. The CirKular+ Performance Enhancement Series allow to increase the content of post-consumer recycled plastics and improves the recyclate’s impact strength. The tested technologies were blended with virgin HDPE or PP resins while representing up to 5% of the total weight of the material.
RecyClass endorsed the recyclability tests carried out by Plastic Technologies, Inc. (PTI) according to The Association of Plastic Recyclers (APR) Critical Guidance for both HDPE and PP Rigid Containers. In addition to this, the production of blow-moulded bottles was performed as required by the RecyClass Recyclability Evaluation Protocol for HDPE Containers. Those tests showed that ‘CirKular+ C2000 & C3000’ conforms to the European rigid HDPE and PP recycling streams when the set conditions are fulfilled. These stipulate, among others, that the amount of ‘CirKular+ C2000 & C3000’ can be up to 5% compared to the total weight of the packaging. Additionally, any attachment or decorative technology applied to the packaging should be in line with RecyClass’ recommendations.
Recycled plastics generated from the recycling process of ‘CirKular+ C2000’ & ‘C3000’ can be used in high-value applications, with up to 25% concentration. The compatibility of these innovative technologies with recycling is yet another step on the way to the establishment of a genuine circular economy for plastic packaging.
