RECYCLED COMPOUNDS | MATERIALS
GR20 BK002 DA offers high stability and low moisture absorption properties, and is used in heating, ventilation and air conditioning compo- nents. Tecodur Eco grades feature a blend of PBT and recycled PET that meet requirements for lighting applications due to their good thermal stability proven in the automotive industry. In addition, Tecomid NA40 CF30 BK111 HS is a black PA66 compound that is 30% reinforced with recycled carbon fibre and is heat stabilised, which provides a tensile strength of 225 MPa and a tensile modulus of 18,000 MPa. Elix Polymers has launched the E-Loop brand to highlight new sustainable innovations. One of the first product introductions in the mechanical recycled materials group is E-Loop H801 MR, a countertype of the standard high heat and high impact grade Elix ABS H801. This new grade has been formulated using post-industrial recycled PC as reinforcement to the ABS prime resin. This material is commercially available and is mainly used for exterior and interior painted automotive applications. However, it can also be used as a pre-coloured alternative. The paintability of the new E-Loop H801 MR grade has been validated by several tier companies and paint suppliers. Tests based on the Daimler DBL 5425 and BMW GS94007 standards have been carried out to verify the paintability of the plastic substrate using several paint systems. The performance shown in all cases is equivalent to the standard alternative, including adhesion and surface quality characteristics. In addition, the PVD metallisation decorative
process was validated by one of the largest compa- nies in the production of lighting systems for the automotive industry with good results. Paint and PVD metallisation validation tests are part of the high- quality requirements that Elix Polymers is applying to the development of upcycling mechanically recycled materials with less restrictions of use in high perfor- mance parts, which also includes emission tests or extensive and high-quality characterisation levels for mould-filling simulation software. LyondellBasell has extended its Circulen range
of sustainable compounds to its Advanced Polymer Solutions (APS) segment. LyondellBasell’s Circulen portfolio of compounds and solutions is derived from mechani- cal and chemically recycled and renewable-based materials for its customers in areas such as automotive and household appliances. The APS segment produces and markets compounds and

solutions, such as PP compounds, engineered plastics, masterbatches, colours and powders, engineered composites and advanced polymers, including Catalloy and polybutene-1. The company is now manufacturing PP and PE on a commercial scale with measurable and certified C14 renewable content (mass balance) from renewable feedstock. The renewable feed- stock – CirculenRenew – is supplied by Neste and is 100% produced from bio-based waste and residues, such as used cooking oils. The renewable content in this grade of CirculenRenew is meas- ured by a third party to ensure that the C14 content of the polymer is consistent with renewable feedstocks and stated as a parameter on the Certificate of Analysis (CoA). Furthermore, these new CirculenRenew grades are drop-in solutions and therefore do not require any modification of existing processing equipment. With the support of Greiner Packaging, CirculenRenew polymers are now being used to make coffee capsules for Nestlé’s Nescafé Dolce Gusto, meeting the strict requirements of the food industry. Both Lyondell- Basell and Greiner Packaging sites involved are ISCC PLUS certified. SABIC has launched the first automotive grades containing mechanically recycled content within the company’s Trucircle portfolio. The new resins are: SABIC T2E-3320EH PP compound, a high-flow, low-emission, talc-filled PP; Xenoy T2NX2500UV resin, an unfilled, UV-stabilised blend of PC and PET; and Xenoy T2NX5230 resin, a mineral- filled PC/PET blend. All three materials contain up to 29% recycled content and
offer good performance similar to that of the incumbent virgin resins. The new products are the first of many SABIC April 2022 | INJECTION WORLD 37
