Frequently asked questions (FAQ)

What does compression hardness mean?

The compression hardness or also called compression resistance is the pressure required to compress a foam. At a compression hardness of 60, 6.6 kPa (kiloPascal) is required to compress the foam to 40%. The compression hardness of a foam is its strength.

What does density mean?

The density is the weight of the foam in kg/m? (kilogram per cubic meter). The weight or density of the foam is also an indicator of quality, the higher the density, the more long-lasting the quality. However, the density has nothing to do with the perceived degree of hardness. As a rule, lighter foams are cheaper because less material is needed.

What are standard foam qualities?

The density and compression hardness describe the technical quality of a foam. The compression hardness describes the indentation behaviour of foams at a defined force. The higher this value, the harder the foam feels. An important quality feature of a foam is its density or volume weight (m3 kilograms per cubic meter). As a rule of thumb: -20 - 30 kg/m3 => Quality for seat and back cushions, low-priced mattresses, -30 - 40 kg/cbm => Standard to upscale quality for seat and back cushions, mattresses, boat, camping or garden cushions etc. -40 - 50 kg/cbm => high to very high and very good permanently elastic quality for a wide range of applications

Can you produce custom-made foams?

According to your specifications, we can produce almost all geometries on our wide range of processing options such as punching, water jet cutting, contour cutting, shape cutting or cutting plotter. Which process is best suited for the desired foam cutting depends on the foam used as well as the required quality and quantity.

How can foams be cut to size?

If you would like to cut the foam to size yourself, there are various possibilities to cut the edges straight and clean. Foam can be cut mechanically with a band saw with a fine-toothed or toothless blade. Foam with a thickness of 20 mm - 30 mm can still be cut very well with sharp scissors. However, if you want to cut thicker foam, you will get very good results with an electric meat knife. Due to the two counter-rotating blades, the material is cut very precisely and cleanly. If you do not have an electric knife at hand, you can also use a conventional bread knife. The bread knife should have a serrated edge. Cutters or meat knives with a smooth blade are not recommended, because the knife becomes dull very quickly and you get frayed edges. a little vegetable oil on the recommended knife blade helps to simplify the cut. Another possibility: So that a "clean" cut is possible, it is advisable to treat the foam with some pressure (using a ruler) and compressit as much as possible to "0" and in this condition use a sharp Cutter to cut through in one go.

What does closed cell/closed pore mean?

The closed cell foams have a different cell structure than open cell foams. In the closed cell foams, each cell is a complete closed sphere containing air in each cell. In contrast to open-cell foams, closed-cell foams do not allow water, moisture and dust to penetrate the cell structure. The closed-cell foam is ideal for sealing, wherever dust and water must be kept away.

Cushions for armchairs, chairs, sofas, lounge camping mattresses and much more.?? A good cushioning requires filling materials. Foams are particularly suitable for this purpose, which you can obtain from us in various forms or qualities for upholstering armchairs, chairs and sofas. Which foam is the right one for your needs depends on the demands you make on the product. There are foams that are rather soft and are perfectly suitable for soft seat cushions, however, it is rather unsuitable for a lounge chair and another foam might not be suitable for soft seat cushions etc.? The conventional variant and also the cheap one is PUR foam. ?PUR foam can be considered a classic among foams. For various purposes such as seat cushions, seat cubes, lounge cushions, bench cushions etc. this foam can be used. Depending on the density and compression hardness this foam can vary in quality and strength. If you would like to use the upholstery foam in public buildings, restaurants, offices etc., you should pay special attention to fire protection. (e.g. BKZ) Here the following product with BKZ 5.2 would be recommended: Silphon?yellowfoam-FR 40 kg/m3 yellow Fire certificate?? ? The density and compression hardness of the upholstery foam should be in an optimum ratio to each other. A high compression hardness is an indicator that the foam is not very resilient, as a result the foam is softer at a lower value. It can be said that the higher the density, the more material has been used and the higher the quality of the product. As a result, if you want to use foams for bench rests and harder seat cushions or lounge chairs, you should pay attention to a high compression hardness. Accordingly, foams with a lower compression hardness are suitable for soft seat cushions. In principle it can be said - 30 kg/m3 soft quality for seat and back cushions Here we recommend: Article 2019.0111.0009 Blockware PUR-Ether with 32 kg/m3 colour white? PU-ether foam 30 kg/m3 white 30 - 40 kg/m3 for standard/medium to high quality for seat and backrest upholstery, mattresses, boat- camping or garden cushions etc. Here we recommend: Article 2019.0111.0007 Blockware PUR ester with 35 kg/m3 colour blue PU-ester foam 35 kg/m3 blue ? Or with increased fire protection and higher density: Article 2019.0111.0026 Blockware PUR Ether 40 kg/m3 Colour yellow BKZ 5.2 Silphon?yellowfoam-FR 40 kg/m3 yellow Fire certificate?? 40 - 50 kg/m3 for high-quality to very high-quality and extremely permanently elastic quality for all applications Here we recommend: Article 2019.0111.0003 Blockware PUR Ether 53 kg/m3 Colour white PU-ether foam 53 kg/m3 white".
