What are the main types of foam (PUF)?
Polyurethane foam (PU foam) is a foamed polymeric material obtained by chemical foaming of a mixture of polyols and isocyanates. The main properties of polyurethane foam are its lightness, high level of elasticity, ability to quickly recover its shape after compression, and excellent shock absorption. Due to these characteristics, foam rubber is widely used in the production of furniture, mattresses, pillows, as well as in construction and packaging.
What are the main brands of polyurethane foam?
The modern market offers a wide range of foam rubber, the main brands of which are:
ST – standard foam for basic applications;
EL – Extra hard foam for better support;
HL – extremely hard foam for high loads;
HS – extra soft, super soft foam for maximum comfort;
HR – highly elastic foam that adapts to the contours of the body;
VE – viscoelastic memory foam;
BB – recycled foam, an economical and durable solution;
SM is a fire retardant foam that provides additional fire safety;
CME – non-combustible foam that meets the most stringent fire safety standards.
How to choose the right polyurethane foam for furniture products?
The choice of foam depends on the specific requirements of the product. For seats and mattresses, we recommend using high-density polyurethane foam with optimal stiffness (EL, HR or VE) to ensure proper support and comfort. If you need a material for decorative elements or packaging, you can choose standard ST foam or ultra-soft HS foam. The main parameters to pay attention to are density (in kg/m³), stiffness (in kPa), elasticity and wear resistance of the foam.
Does non-combustible foam exist and how is it used?
For example, non-combustible foam, in particular, CME brand, is manufactured using special additives that ensure a high level of non-combustibility. This type of polyurethane foam meets strict fire safety standards and is widely used in the production of furniture for public facilities, vehicles, and building structures. CME non-combustible foam guarantees safe operation and prevents the spread of flames, while maintaining its shock absorption properties.
How does the density of polyurethane foam affect the quality of foam?
The density of the foam, measured in kg/m³, is one of the key quality indicators of polyurethane foam. The higher the density, the more material is in one cubic meter, which provides better support, wear resistance and resistance to deformation. The optimal density of the foam guarantees an even distribution of the load, increases comfort and extends the service life of furniture products. Choosing the right density of polyurethane foam allows you to achieve the desired performance characteristics of the finished product.
What technical characteristics of polyurethane foam are important to consider whenordering foam?
When ordering polyurethane foam (PU foam), you should pay attention to the following main technical characteristics: density (kg/m³), stiffness (compression direction in kPa), elasticity, wear resistance, and residual deformation. These parameters determine the comfort, support and durability of foam products. Choosing the optimal characteristics of polyurethane foam allows you to create furniture foam that meets high quality standards and ensures the stability of the final product.
What sizes and thicknesses of polyurethane foam (PU foam) can be made to order?
We can produce polyurethane foam (PU foam) of any size and any thickness on an individual order. Standard sizes are 1.2×2 m and 1.6×2 m sheets. However, for special products, we can provide the material in any size. The thickness of the foam can vary from 1 cm to 10 cm or more, which allows you to optimally select the polyurethane foam for the manufacture of both decorative layers and the main load-bearing elements of furniture products.
