PU-Foaming

When designing modern vehicles and appliances, there is often a need to satisfy a whole range of potentially conflicting requirements, such as reducing noise while at the same time reducing weight. Carcoustics uses polyurethane (PUR) and other supplementary materials to develop solutions to address such complex problems.


The engine compartment of a car provides a prime example of the demands placed on materials, and formed parts, in order to provide insulation that is both intelligent and reduces consumption. The better an engine compartment is insulated, the slower the engine cools down, which means that it doesn't have to be started from cold so often, which, in turn, can significantly reduce consumption and emissions. However, heat-sensitive components in such a well-insulated area also need to be better protected. Noise reduction, ride comfort and aerodynamics also need to be maximized, and the only way to achieve this without adding additional weight is through developing new, lightweight components.

Carcoustics – a flexible partner for a flexible choice of materials

Carcoustics is currently enjoying a period of dynamic growth thanks to the growing demand for PUR products. We have worked with all the major European and American OEMs and many TIER 1 customers in the automotive sector as certified partners for many years.

The demand for polyurethane products in the automotive industry is growing steadily, and not just because of its light weight. The fact that it can be adapted to a wide range of applications and specifications in terms of shape, function and material properties makes it a particularly effective choice for thermal and acoustic components. Carcoustics makes use of its versatility to create customized solutions.

Additional Functions on Demand

By combining PUR foams with other materials, Carcoustics can offer its customers additional functions to meet their needs. The foams can be encased in foil to protect them against spray water, for example. Or, if there is a need to improve acoustics, voluminous nonwovens and heavy-layer matting can be incorporated.  Components can also be protected against heat or used as heat shields themselves by the addition of aluminum inserts to reflect radiated heat.   If the customer so  requests, components can also be made flame-retardant with an operating temperature of up to 150°.

Many Kinds of Foam

In order to be able to meet the needs of as many customers as possible, Carcoustics offers a wide range of soft, heavy and integral foams with bulk densities ranging from 55 to 400 kg/m3.
