The Meaning And Standard Of Sofa Sponge Density

- May 21, 2018 -

Sponge is one of the indispensable materials in the structure of the sofa, and it is also the most important. It plays a decisive role in the sofa's soft and hard comfort. In general, sponges are classified according to their density. The so-called density is the weight per cubic meter of sponge.

 

Density is an important indicator of sponge quality. The higher the sponge density, the smaller the gap between the sponges. For example, a 30-density sponge means that a cubic meter of sponge has a weight of 30 kilograms, a 40-density sponge means that a cubic meter of sponge has a weight of 40 kilograms, and so on. But now some manufacturers, in order to achieve high-density standards, will not meet the standard sponge by adding talcum powder to increase the weight of the sponge, so the criteria for distinguishing the quality of the sponge we should focus on rebound or compress the effect of deformation above . Normally, the higher the density of the sponge, the higher its hardness, but if super-soft additives are added, it will become super soft again. Therefore, the same density of sponge hardness and hardness are not necessarily the same.

 

   The more intuitive feel of a sponge is its elasticity and softness. Therefore, the sponge can be divided into high rebound, low rebound, hard, soft, super soft points. With regard to the interpretation of the density of sponges by national authorities, high-density sponges are used for density higher than 45, medium density sponges for 45-18, and less than 18 for low-density sponges. It is used to make sponges for sofas. Different densities of sponges can be used according to different parts of the sofa, but high quality sponges are generally highly resilient.
