The IAA Transportation trade fair for the commercial vehicle industry in Hanover, Germany (September 20-25) will see Continental present sustainable and functional surface solutions for the diverse requirements in the driver’s cab.

“Our sustainable product design is based on three pillars: carbon neutrality, circular economy and unique product properties as enablers,” says Dr. Dirk Leib, Head of the Surface Solutions business area at Continental. “We’ve already achieved considerable success with our products on this path to sustainable vehicle interiors. In this way, we can now create customer-​specific surface solutions that are up to 100 percent climate-​neutral,” explains Leib.

The path to carbon-​neutral products presents challenges in many areas such as raw materials, production processes and energy consumption. For sustainable product design at Continental, substituting classic petroleum-​based raw materials with recyclable and bio-​based raw materials is crucial. The company’s surface specialists are also focusing on degradable solutions in development processes, and current sustainability measures are flanked by continuous efforts to substitute critical contents and minimize emissions and odors.

Bio-based products, designed for recycling
Today, the surface material Xpreshn can already be produced with renewable raw materials, and it provides a solution that is both light and environmentally friendly. “With bio-​based Xpreshn, we can deliver a product with an optimal CO2 footprint that combines excellent technical properties and a large range of design options,” says Dr. Gabriele Wittmann, Head of Global Surface Research at Continental.

Recycling is an essential step toward conserving resources. The goal is to close the cycle of a product. The development of single-​variety composites – monomaterials – enables recycling processes from which high-​quality raw materials for new or original products can be generated. Xpreshn, the material for door panels and the instrument panel, can also be realized as a completely recyclable monomaterial, which means that it can be returned to the circular economy in its entirety.

Xpreshn also offers solutions for recycling concepts with entire components, if the carrier component and the surface are made of the same materials, for instance. Then they can be recycled together at the end of their service life.

Continental has already developed numerous products that possess these properties and also retain their proven premium properties. For example, Acella synthetic leather is a durable product with recycled materials and bio-​based raw materials combined with a rPET textile. The yarns to produce the textile for the rear coverings are made from recycled plastic bottles. As a robust and easy-​to-clean product with a range of highly variable designs, Acella whets the customer’s interest in sustainable products and does not compromise on product properties.

“We can already offer our customers premium surface solutions that are 100 percent carbon-​neutral,” emphasises Wittmann. The key here is substituting classic petroleum-​based raw materials with bio-​based, CO2-​based or recycled raw materials.

Continental's staynu technology makes surfaces resistant to contamination and mechanical and chemical stress caused by cleaning agents, for instance – so the surfaces are durable.

“Our surfaces are designed for maximum performance and are also lightweight and robust,” emphasises Wittmann. A longer service life also contributes to sustainability, even under high stress levels, particularly in shared mobility concepts and commercial vehicles. “Our staynu technology makes surfaces resistant to contamination and mechanical and chemical stress caused by cleaning agents, for instance – so the surfaces are durable.” Currently, the staynu technology is mainly used on seats and add-​on parts, but in the future, it will also be possible to use it for the instrument panel.
