Kraiburg TPE to launch the world’s first weight-saving TPEs

KRAIBURG TPE has developed an innovative material technology that enables the production of thermoplastic elastomers (TPE) with very low density. The result is three new product lines for extremely weight-saving components of a type that is in increasing demand for vehicle construction, power tools and various other application areas.

To further reduce CO2 emissions from vehicles and to improve the fuel economy and range of new models, automobile manufacturers are always looking for extremely lightweight solutions – particularly for unsprung weight in and on their vehicles. But lower weight and increased mobility also play a decisive role for the market success of products in other sectors such as power tools, aviation, drones, textiles, as well as sports, leisure and outdoor items.

Expandable materials including TPE are therefore often used, but they require strict process control procedures to achieve an even surface quality without surface waviness.

Kraiburg TPE has now been able to implement an outstanding new TPE technology by using 3M Glass Bubbles for materials with very low densities of between 0.7 and 0.9 g/cu cm (1.358 and 1.746 slug/cu ft) that allow the production of extremely lightweight thin-walled mouldings that provide excellent surfaces and are able to withstand mechanical loads.

The microscopically small hollow glass bubbles are made of chemically stable borosilicate glass that is insoluble in water. They spread evenly in the TPE matrix and help increase the dimensional stability.
