Foam rubber is used in furniture production, as insulation, for door upholstery, packaging, etc. What characteristics of this material do you need to know about? What properties does it have? How to apply in a specific situation? We will deal with all these questions in the article.
The technical name of foam rubber is polyurethane foam (or PPU for short). It may differ in a number of parameters. The properties of polyurethane foam are determined by the following mechanical and physical indicators:
- Density;
- Rigidity;
- Breaking strength;
- Residual deformation;
- Air permeability;
- Elasticity;
- Relative elongation;
- Cell size;
- Comfort;
- Reference coefficient.
The last two parameters apply to highly elastic foam rubber.
These characteristics determine the range of application of a particular type of foam rubber in a particular production. That is, how convenient it will be to use polyurethane foam when creating certain furniture.
To understand this issue, let's consider the key parameters of polyurethane foam.

What orthopedic foam is used in expensive mattresses?
The most suitable for use in mattresses are foam rubbers with a density of at least 30 kg per m3.
This density is sufficient to support a sleeping person for a number of years. Of course, significant factors are the softness and elasticity of the foam. Without competition for the production of comfortable, high orthopedic PU foam mattresses with HR marking. They are often called artificial latex, and unscrupulous sellers sometimes pass them off as natural latex. To understand this issue well, we recommend reading our article about how different these materials are and how they affect health. In addition to excellent physical properties, these materials have virtually zero release of foreign substances. These cold foams are used in expensive European mattress models. The service life of HR50 foam is about 15 years. Such materials are expensive and are never included in cheap mattresses. In this video, a mattress manufacturer talks about various orthopedic foams.

- has high elasticity;
- has a high degree of sound insulation;
- retains properties over a wide temperature range;
- does not cause allergic reactions.
Polyurethane foam for furniture is not a favorable environment for insects. It is moisture resistant and can be used at temperatures from -40 to +100 °C. In the furniture industry, foam rubber has also found its use due to the fact that it has the ability to take the necessary shapes.

Classification by release form
Polyurethane foam for furniture can also be divided by shape. Products can be:
- roll;
- leafy;
- block;
- acoustic.
The leaf variety has a rectangular shape, and the thickness of the blade can reach 1000 mm. Manufacturers supply such polyurethane foam in standard cuts or take into account individual customer requirements. The roll type comes in reels of different widths. The material is easy to use, and its thickness does not exceed 30 mm.
ENSURING THE SECURITY OF PERSONAL DATA
The security of personal data processed by the Operator is ensured by the implementation of legal, organizational and technical measures necessary to ensure the requirements of federal legislation in the field of personal data protection.
To prevent unauthorized access to personal data, the Operator applies the following organizational and technical measures:

Main quality indicators of furniture foam rubber
The quality and purpose of foam rubber is influenced by its following physical properties:
- density, the higher the density of the foam rubber, the longer its service life;
- compressive stress, the magnitude of the force in kPa to compress the sample by 40%;
- strength, tensile strength and elongation at break;
- elasticity, a value inversely proportional to stiffness, measured by the height of the rebound during testing;
- residual deformation, the ability to return to its original state after removing the load; the higher the density, the lower the residual deformation;
- comfort, comfort and support coefficients - softness with low compression and ability to distribute load accordingly.
In the designation of foam rubber brands, the letters indicate the class of the material, the first two digits are its density, the remaining two digits are the compression stress.
Using the EL 2535 brand as an example, we can say that the material has the following properties:
- EL – high-hardness grade;
- 25 – density 25 kg/m. cubic;
- 35 – compression stress 3.5 kPa;
