Sponge Is One Of The Indispensable Materials In The Structure Of The Sofa

Oct 09, 2017

Sponge is one of the indispensable materials in the structure of the sofa, and most importantly, it plays a decisive role in the soft and hard comfort of the sofa. General sponges are in accordance with the density to distinguish between grades, the so-called density refers to the weight of each cubic meter sponge how much.

Density is an important indicator of sponge quality. The higher the density of the sponge, indicating that the gap between the sponge will be smaller. For example: 30 density sponge refers to a cubic sponge weight is 30 kg, 40 density sponge refers to a cubic meter of sponge weight is 40 kg, and so on. But now some manufacturers, in order to achieve high-density standards, there will be no standard sponge by adding talc to increase the weight of the sponge, so the criteria to identify the quality of sponge we should focus on rebound or compression with or without deformation effect The Under normal circumstances, the higher the density of sponge its hardness will be high, but if added super soft additives, it will become super soft. So the same density of sponge soft and hard degree is not necessarily the same.

Sponge gives a more intuitive feel is its flexibility and flexibility. So sponge can be divided into high rebound, low rebound, hard, soft, super soft points. With the relevant state departments for the interpretation of the density of sponges, density higher than 45 density for the high density sponge, density between 45-18 for the density sponge, low density sponge is less than 18. Used for sofa material sponge, according to the different parts of the sofa, the choice of different density sponge, but the quality of the sponge are generally high rebound.
