Kraiburg TPE (Waldkraiburg, Germany) is presenting thermoplastic elastomers (TPEs) that have a variable proportion of renewable raw materials.
By introducing these new compounds, the global TPE manufacturer is expanding its THERMOLAST®R range of more sustainable solutions by adding a line of products from renewable raw material sources. Biobased TPEs also have a lower product carbon footprint than established alternatives that are not based on renewable raw materials.
Sustainability is a key aspect of the design phase. It is only when the idea of sustainability plays a major role from the very start of a project that it can contribute to the project’s success in the longer term. Kraiburg’s customers already have access to more sustainable compounds that contain proportions of post-industrial or post-consumer recycled materials, particularly in the consumer and automotive sectors. Kraiburg is now complementing its range of more sustainable solutions by adding biobased TPEs made of raw materials that support the transition from compounds based on fossil resources to alternative products based on renewable materials and make this transition attractive.
Using biobased TPEs can reduce a product’s carbon footprint (PCF) by up to 50 % as compared to TPEs made of fossil-based materials. PCF refers to the total amount of greenhouse gas emissions, particularly carbon dioxide (CO2), associated with the production, usage, and disposal of a particular product or service. Transparency and understanding the PCF can enable end customers and processing companies to make informed decisions when selecting materials in order to produce and market more sustainable products. This aspect is currently of interest in all markets where there’s a demand for materials with reduced carbon footprints. By using renewable raw materials in the production of biobased TPEs, Kraiburg is actively helping customers to achieve their sustainability targets.
Biobased TPEs provide neutral odour, touch, grip, and adhesion properties that are highly comparable to those of fossil-based TPEs. The new products include solutions such as compounds with adhesion to PP, ABS/PC and PA within a hardness range between 30 and 85 Shore A. Individual compounds have a bio-content of more than 60%. Both compounds with adhesion to PP and to polar materials can be coloured. The materials have been thoroughly tested in injection moulding and extrusion and have processing properties comparable to those of fossil-based TPEs. The biobased/biogenic carbon content is traceable according
to ASTM D 6866.
“With biobased TPEs, we are filling a gap in our portfolio and taking another step toward more sustainable TPEs. Our biobased TPEs provide more sustainable solutions, while maintaining the usual performance and reducing the product carbon footprint. We are looking forward to projects that enable us to make the transition from fossil-based to more sustainable raw materials”, sums up Tobias Brückner, Project Manager Advance Development at Kraiburg TPE.
Biobased TPEs are currently produced in Germany and are available worldwide immediately. AT
