Bedding

PU Foam plays an important role in the manufacturing of mattresses, toppers and pillows. Combining different densities, hardness’s and cell structures will provide different sleep comfort. Even when you are a big fan of spring mattresses, also there is foam inside. Traditionally this application/market segment has been using foam as one of the first in the global industry.

Furniture

Similar as in the bedding industry, PU foam is used to provide a comfortable seating. The difference is that here the foam is more active and less soft as it needs to support more. Except for pure wooden or metal furniture there is almost no piece that does not have foam inside it.

Filtration

Ensure that unwanted particles or pieces find their way into the production process/living area or any other location is an important function of PU foam. It is used for the filtration of gasses, liquids and even melted metal such as steel. Given the open cell structure and the ability to control the sizes of the cell, PU foam can support filtration of a large number of materials. From you A/C to your car, and from your aquarium to your swimming pool.

Sealing

Gasketing or sealing is used to ensure water or other materials to leak from the area where it needs to be. Using PU foam in thermal compressed shape enables this sealing capability. As such it is then being used in various applications; automotive, construction (windows) or hydraulic equipment such as cylinders. The original open cell structure is being closed by thermal compression and making it an excellent gasket.

Automotive

Volume wise the largest industry where PU foam is being used. An average car contains around 17 kilograms of PU foam, in various places. The obvious one being the seating, where molded PU foam is used to shape the perfect seat. But in various other places for luxury feeling in the door panels and headliners, or the textile/leather which is being laminated with foam to give that extra resilience and comfortable feeling.

Footwear

The functions of PU foam in footwear are to provide comfort and protection. Both as molded foam (e.q. soles) as well as slab stock foam to be used in the sides, tongue and cover. A special application is to protect the foot from heavy weight pressing the steel nose in the foot.

Thermal insulation

One of the capabilities of PU foam is to absorb energy and heath. As such it is being used to keep in the cold as well as the heath. For example a water boiler has foam inside to make the energy loss lower, at the same time a refrigerator also has PU foam inside to keep the inside temperature low. Depending on density and cell structure, these capabilities can be increased or decreased.

Cleaning

The oldest application for PU foam as the original material was designed to replace natural sponges which were growing on the bottom of the seas. The foam has a larger and coarser cell structure with hydrophilic characteristics.

Underwear

To support the shape of the brassiere a special foam has been developed which can be made in different colors, hardness’s and thickness. The foam has been treated to prevent the yellowing which is normal for polyurethane foam under the influence of UV, temperature and humidity. To ensure the foam color does not interfere with the fabric, this foam will have a much longer whiteness.

Acoustic insulation

To ensure a better acoustic, PU foam is used to decorate walls and ceilings in many concert halls and sound studios. By providing specific cut shapes, the insulation and reflection of sound is further enhanced, providing calm and rest for the people outside and enjoy for the people inside. It is a win-win situation

Conductive Foam

In order to improve the conduction of power through an appliance, the foam is made conductive by adding specific additives. This application you will find for example in printer/toner cartridges where this type of foam is used to clean the surface

ESD

Electrostatic discharge foam, or ESD is important in an environment where electric shocks can damage the products. A well known application is floor mats for the assembly of printed circuit boards (PCB’s).
