From the rubber compound to the product design

We see ourselves as material designers. And for us, this starts with the composition of the compound. We develop an individual rubber compound for each conveyor solution in terms of material structure, properties, color and certifications. This means that there are practically no limits to the areas of application – even under extreme conditions.
