A new level of puncture resistance thanks to Elastollan

29/08/2022
Thermoplastic elastomers
With the market launch of its new Aerothan bicycle tube on October 8, Schwalbe presents a new generation of bicycle tubes based on Basf thermoplastic polyurethane (TPU) Elastollan. This innovation scores top marks in terms of weight, puncture resistance, handling characteristics, ease of assembly and packing size. Aerothan bicycle tubes are the result of unique developmental work between the market leader for bicycle tires and tubes in Europe and Basf's Performance Material Division.
 
The new Aerothan bicycle tubes are designed around a specially developed material combination based on Basf Elastollan. The close cooperation is characterized above all by the targeted material development and tube prototype production at Basf's Lemförde Technical Center, followed by tube assembly and intensive testing at Schwalbe. As a result, the optimum mix of materials and processing has been achieved, such that the new bicycle tube not only offers good performance, but is also around 40 % lighter than the established alternatives on the market. To achieve this, all parts of the new tube, including the valve stem, are made entirely of Elastollan. The advantage of the reduced weight is not limited to just better handling, but is also evident in the smaller packing size, which makes the Aerothan tube an ideal backup tube.
 
Despite its low weight, the new tube offers cyclists a whole new level of puncture safety: the material prevents any sudden loss of air and ensures stable handling even at low tire pressure. Aerothan bicycle tubes are therefore approved for all rim brakes and so are perfectly suited to the high demands of racing bikes, mountain bikes or all-round cycling environments. Since Aerothan bicycle tubes can be changed quickly and easily without slipping or jamming, they are also easy to install in practice.
 
This is enabled by the special mechanical properties of TPU plastic. Elastollan is highly resistant to abrasion and wear and is therefore extremely durable, even under sustained high pressure loads. At the same time, the material is extremely flexible, elastic and heat resistant. Another advantage of the Aerothan bicycle tubes is their recyclability - they are made entirely of thermoplastic polyurethane. Like all Schwalbe tubes, Aerothan bicycle tubes can be returned to the manufacturer, easily and free of charge, via the tube recycling program. The material of the old tubes is processed and then reused as sealing or insulating material.
