New plastic application for more safety in ice and snow

Mar 11, 2016

The snow chains made from the two Elastollan® grades are suitable for different tire sizes and easy to fit.

Even at low temperatures plastic can efficiently substitute metal: the French textile and rubber company Joubert Productions, Ambert, is for the first time putting snow chains on the market whose chain links are made entirely from plastic. This has become possible with Elastollan®, the thermoplastic polyurethane (TPU) from BASF. The snow chains meet the ÖNORM 5117 standard.

Elastollan® possesses important qualities as, for example, high flexibility at low temperatures and a road grip enabling car drivers to enjoy the best possible control over their vehicles on snow-covered roads.

Further advantages of the TPU material become visible during the injection-molding production program: Two Elastollan® grades of different colors are chemically adhered to one another and therefore, do not have to be additionally assembled – as it is necessary with the conventional metal chains. The plastic material thus offers an excellent combination of lightweight construction and serial production.

“Tailor-made quality products are the most important part of our business. BASF not only supported our idea of producing lightweight, easy-to-fit snow chains by providing the right material. What is crucial for us is that BASF has been with us right from the initial idea via finding the appropriate mold through to the finished product, thus enabling us to set up with an optimum production process,” says Régis Kaelin, who is responsible for Reseach & Development at Joubert. “This means we are not only able to manufacture products efficiently, but can also offer car drivers a high level of safety in winter with snow chains that can be used without any problems.”
