Kraiburg TPE to develop renewably-sourced thermoplastic elastomers

Kraiburg TPE to develop renewably-sourced thermoplastic elastomers

Kraiburg TPE is starting an ambitious campaign to develop custom-engineered thermoplastic elastomers containing variable proportions of renewable raw materials.

Tmhe company will create customer-specific and application-specific compounds using renewable raw materials, in order to meet the growing demand for environmentally friendly and sustainable thermoplastic elastomers.

Climate change, finite oil resources and customers who are increasingly environmentally aware are leading more and more materials manufacturers and users to turn to “renewable” and “bio-based” solutions. However, “bio” is a broad term that is by no means synonymous with “sustainable” in the sense of a strategy for saving resources and protecting the environment. Renewable raw materials also have carbon footprints, as well as water footprints, that can have an impact on the environmental balance, depending on their provenance and the way they are grown. Factors that play a decisive role here include irrigation, fertilizers, transport energy and energy consumed for reprocessing.

“Part of the challenge involves taking into account the environmental balance of the materials’ whole life cycles, including their impact on ecosystems and people’s health,” said Franz Hinterecker, CEO Kraiburg TPE.

“It has also become apparent that what our customers expect from the properties of ‘bio-materials’ varies widely depending on the application – while at the same time we have to meet strict criteria regarding the materials’ conformity and performance.”

In its Code of Conduct, Kraiburg TPE has committed itself to sustainable business operations and to protecting the soil, water, air and biological diversity. Environmentally harmful impacts are to be prevented by appropriate environmental protection measures, and resources are to be conserved. Based on these principles, Kraiburg TPE’s modular system makes it possible to develop customer-specific materials with different proportions of renewable raw materials. Typical performance characteristics that are also relevant here include mechanical properties such as tensile strength and elongation, as well as processability, heat resistance and adhesion to ABS/PC or PP and PE, for example. The requirements are determined in close collaboration with each customer and translated into a sustainable and cost-effective solution by our developers.

Using the traditional approach, it is technically possible to produce bio-based materials with very high proportions of renewable raw materials. However, materials of this kind usually suffer from very high raw materials costs, while providing only very limited mechanical properties. Kraiburg TPE’s modular system has now enabled this contradiction to be resolved. The initial pilot projects based on the classical approach are showing a trend towards bio-based, certifiable proportions of 20% and more.

Their potential use extends to all TPE applications in the consumer, industry and automotive markets. Examples range from toothbrushes and hypoallergenic elastic watch straps to fender gaskets.

“The approach we’re taking is being well received particularly by customers who are looking for sustainable solutions but don’t want to do without cost-effectiveness and performance,” Mr. Hinterecker added. “Our core competencies – a strong customer focus, global presence and trendsetting innovations – mean we are in a good position to meet these challenges.”
