Bio-Based Thermoplastics For Extrusion And Injection Molding

At Fakuma 2018, FKuR will present its broad portfolio of bio-based thermoplastics for injection molding, thermoforming and extrusion, including the advanced injection molding grade Bio-Flex S 7514 as well as bio-based TPE and PP grades for a variety of applications.

Bio-Flex S 7514 is a biodegradable compound based on polylactic acid (PLA), which has been optimized by FKuR for particularly comfortable and efficient processing.

Thanks to its good flowability (MFR = 27 g/10 min), it is also suitable for use in multi-cavity molds and the production of parts with longer flow paths. The high heat resistance (Vicat A = 110 ° C), which is achieved without hot tool, allows for shorter cycle times.The material has a bio-based content of 75% and is available in both natural and white. Other colors can be achieved by using a multiplicity of masterbatches.

In addition, the variety of bioplastics from FKuR also includes bio-based thermoplastic elastomers (TPE) as well as compounds based on polypropylene (PP).

Terraprene, the bio-based TPE compounds for extrusion and injection molding, has a bio-based content of 40% to 90%. It offers the same mechanical properties as its fossil fuel based counterpart and can be processed on existing production equipment and tools. It is also possible to produce complex components using 2K injection molding.

Terralene PP is a PP compound with a bio-based carbon content of approximately 35% (ASTM D 6866). In injection molding and in profile extrusion, it is a true drop-in solution because its performance and processability are comparable to those of conventional PP grades.
