EL3245
Foam rubber EL3245
High load-bearing foam EL3245 is a cellular polymer material that is polyurethane. The latter is formed by the reaction of a polyol with a polyisocyanate, as a result of which the resulting polymer mass foams due to the release of gases. The gases are subsequently spontaneously replaced by air. The volume of the resulting mixture is tens of times greater than the volume of the original components. Different combinations of polyisocyanate and polyol provide the required hardness or softness of the finished polyurethane foam (polyurethane foam or foam rubber). In addition to these two components, foam stabilizers, modifiers, silicone and other reagents are also added that help improve certain indicators or achieve the required properties.
EL3245 furniture foam has a structure that can withstand higher loads than standard brands. This type of polyurethane foam is designated by the letters HL. The density of such foam rubber can be different (from 20 to 40 kg/m3), since this indicator depends on the degree of gas filling, that is, on the number of air bubbles. Since the cell walls are thinner, the more gases released during the reaction, the elasticity of foam rubber with a lower density is lower. Foam rubber with increased rigidity is suitable for the manufacture of furniture parts that are forced to undergo severe loads during operation. For example, seats and backs of chairs, sofas, sofas, poufs. It has also found its application in the manufacture of mattresses. Polyurethane foams are characterized by the ability to quickly return to their shape after the cessation of mechanical stress. They owe this property to their high elasticity.
Hard foam rubber for a sofa, despite its name, is quite soft and easy to process mechanically. You can easily cut a piece of any suitable shape from it. At the same time, it is also suitable as a top mat, which is placed on the springs. When used, this material does not emit toxic compounds and can withstand a wide range of temperatures - it can withstand even the harshest winters and hot summers in Russia with ease.
High durability, good shock-absorbing properties, resistance to many aggressive chemicals, harmlessness to health - all these qualities are inherent only in materials manufactured in compliance with technological standards. Therefore, hard foam rubber, the price of which is much lower than the market price, should at least cause distrust in the buyer. To avoid having to later regret wasted money, the best option is to buy products from companies with a decent reputation. Such as the production enterprise "KhimPlastServis", which is responsible for the final result.
