Foams are found in countless applications. Mattresses and upholstered furniture are just two examples where we come into contact with foams in everyday life. But there are many more!
Our world at Greiner consists of plastic, but also of foams. As a leading manufacturer of special foams, Greiner Foam deals with the latter on a daily basis. Our product portfolio is diverse and ranges from foams in mattresses, aircraft seats and functional trim parts for the automotive industry to various insulation applications and foam product solutions in the health care sector. Thanks to their high quality, our products permit an increase in the safety and efficiency of the end products in which they are integrated. As part of the continuous development of our product portfolio, we always focus on finding more sustainable solutions and materials.
In order to increase the use of sustainable raw materials, we analyze sources of sustainable raw materials with comparable structures and similar material characteristics to conventional plastics or foams. Plant oils are already used in the polyurethane industry. For many end products in which Greiner Foam products are used, weight is a decisive factor for energy efficiency and thus for the ecological footprint. Greiner Foam concentrates on innovative solutions that support its customers in the production of sustainable and energy-efficient products. Through innovative product examples that show the commitment of Greiner Foam to sustainable and recycled materials, our products contribute to more efficient end products – for instance, also at Greiner, our full-service provider for the aviation sector whose structural cushion makes it possible for seat manufacturers to replace the seat shell. Compared to conventional solutions, this means an average reduction in weight of around 600 grams per seat or an average of 150 kilograms per airplane.
Other examples of sustainable product solutions are:
PERmold®75 – a product from Greiner Perfoam – uses PUR cut waste for the development of acoustic products for the automotive industry. It consists of 95 percent recycled secondary raw materials from foam packaging and thus enables an eco-efficient reuse of this valuable raw material. Through the optimization of the flake geometry and adjusted tool concepts, our solutions reduce the weight of the material by 25 percent with the same acoustic and functional efficiency and thus contribute to reducing the consumption of fuel in vehicles.
With Modul® VIP – the insulation solution from Greiner PURTEC – energy consumption of hot water tanks can be reduced by 50 percent. This corresponds to a saving of 910 kilograms of CO2 equivalent over the average service life (15 years) for a standard storage tank with a water volume of 800 liters. This is comparable to over 3,000 washes with an “A +++” washing machine for a 4-person household. This is made possible by the use of highly insulating vacuum insulation boards in combination with other high-quality insulating materials.
Our PERcap® acoustic enclosures for automotive engines are a prime example of sustainability in the automotive industry. The sound insulation directly at the noise source allows other acoustic measures in the engine compartment to be carried out in lightweight construction, which means total weight savings of up to 25 percent. In addition, the well-insulated components ensure that the powertrain reaches operating temperature more quickly and cools down more slowly, which results in a considerable saving of fuel. The product also comprises 30 percent sustainable natural fibers and another 30 percent secondary raw materials from plastics recycling. With PERcap®, the end customer gains a lower noise level and greater efficiency in the passenger car sector. The environment costs are also reduced.
