What is a cold foam?
Soft foam is one of the types of foam that can be seen in industry, home, etc. This foam is divided into two groups: cold foam and warm foam. Usually, cold foams are also known as flexible polyurethane cold foams, which gives a more complete description of these materials.
Because cold foams are a sub-branch of soft foams, they have an open cell structure and air flows between the cells. When you press this foam, the air in the spaces between the cells is discharged and the volume of the foam decreases.
Cold foam
which is also called sofa foam has many uses in furniture production and repair. It is especially used in the sitting part of the sofa (the same as the sofa mattress), its support and backs, and it is used in the form of a single piece or a detachable mattress. This product is also used in the production of sleeping mats.
Price of cold foam and factors affecting it
As you know, cold foam has different prices like other products. The raw materials required for its preparation, the quality of cold type foam and its raw materials, the percentage of softness and hardness are among the important factors in the price of foam. But the most important thing about the price of first grade cold foam is the amount of warranty time for it. According to what was said, polyurethane cold foams are very widely used in the production process of car seats, household furniture, motorcycle saddles, etc.
Factors Affecting Cold Foam Price
Construction quality and warranty
The amount of thickness, softness and hardness in the foam
Raw materials used
Dimensions of the foam
Dimensions of cold polyurethane foam
Cold foam is produced in different dimensions and shapes, which can be different depending on the needs of the market and customers. For example, the use of this product for the production of furniture is a common use, and in many cases, the standard pattern for the production of this foam is determined according to the needs of the sofa manufacturers. It is interesting to know that cold type foam can be found in the market with at least 42 different sizes, which mainly exist in 6 general models.
6 cold foam models are:
Seat floor foam
Flat sheet foam
Foam polish
Lens foam
medical foam
Cashew foam
Importance of cold foam
First and foremost, we must know what this foam is and what it is used for. In general, we can say that foams are divided into two groups: soft foam and hard foam. We can also classify and divide soft foams into two categories: cold foams and warm foams, each of which has its own advantages.
The nature and structure of cold foams is that they have open cell structures. These open cell structures are such that air cells can easily move between them, so these foams can deform when you press them. Usually, the volume of these foams is completely virtual and unreal, and the largest volume of these foams is due to the air that flows between the cells and empty spaces of these foams.
The advantages of using cold foam
The general features of cold foams
As we checked, this cold foam is produced with different features and changing any of these features can be effective in determining the price of the foam. Other features of cold type foam include the following:
Manufacturer company
Degree of foam stiffness
The difference between hot and cold foam
Cold foam tips
It is not bad to know that cold sofa foams are made of polymer materials such as polyol, isocyanate, water and various chemical catalysts. In fact, MDI isocyanate is used in this product, which is safer compared to toxic substances such as toluene diisocyanate and produces less toxic gases during production.
These products are suitable and safe for furniture use. Various degrees of hardness have been reported for this product and according to it, they are produced and supplied with different resistance.
Note that the price of cold foam for a sofa is not determined by the degree of hardness of the sofa foam, but the quality of the raw materials, the manufacturer's brand and the warranty of these products are factors affecting its price.
Tips for making cold foams
In order to have a softer cold foam, we must reduce the amount of isocyanate in the foam from its normal and natural limit. The amount of polyol also affects the softness and stiffness of the foam, but its effect is less than that of isocyanate. The next thing that can affect the softness of the foam is its density.
Density is the volumetric weight of foam. The lower the density, the softer the foam. When making the foam, it is necessary to create gaps between the cells and its basic components for air circulation. For this, they should either use compression and tension rollers, or they can create these empty spaces through vacuuming.
