Automotive Solutions from PC and PET Consumer Wastes

PC/ABS materials using recycled PC bottles are in demand for many interior and exterior applications due to the interest in post-consumer wastes as sustainable sources. Even inherent surface quality and high impact properties are key parameter for PC/ABS blends; experiences for proper sourcing, formulation and process technology are very critical for recycled based materials. Tecotek® ECO BC44 UF65 BK013 MB/M65C (PC/ABS, impact enhancer, heat stabilized, black, 65% post-consumer recycled content) provides the expected paintability and adhesion on interior and exterior automotive parts thanks to its superior mechanical and thermal properties as well as its surface properties. It has features. The properties of the material, that characterization tests are carried out in the OEM laboratory, are included in the approved material lists of known OEMs, thanks to their compliance with the specifications.

The use of PBT/PET mixtures using recycled PET bottles, instead of glass fiber reinforced PBT products commonly used in automotive applications, is one of the sustainable automotive applications. Thanks to the high availability and quality advantage of recycled PET sources, PBT/PET blends can meet the expected final properties of critical applications. PBT-based Tecodur® PB70 GR30 BK009 HS (PBT, 30% GF, heat stabilized, black) has a tensile strength of 130 MPa, while Tecodur® ECO PB74 GR30 BK009 HS01/M25C (PBT/recycled) with 25% post-consumer recycled PET content recycled PET, 30% GF, heat stabilized, black) has a tensile strength of 135 MPa. Although it has a 25% post-consumer recycling rate, it is possible to use PBT/recycled PET blend material for various critical parts requiring high mechanical and impact resistance. When compared in terms of carbon footprint values, the material containing 25% recycled PET is ready to be used for many applications as it is a more sustainable solution with approximately 30% lower carbon footprint value (kg CO2eq). Tecodur® ECO PB74 GR30 BK009 HS01/M25C is included in the approved material list of the well-known OEM thanks to its material properties.
