The classification of Sponge Composite Cloth, the commonly used Sponge Composite Cloth is divided into three types: high density, medium density and low density according to the structure. The high-density Sponge Composite Cloth has many pores and is very full, and is often used for materials such as sound-absorbing cotton, sofa cushions, and soft bags.

According to the interpretation of the national customs department, the density ≥ 45 is high density, the density between 45 and 18 is medium density, and the density < 18 is low density.
Hardness of High Density Sponge Composite Cloth
Generally speaking, Sponge Composite Cloth with high density is also high in hardness, but it is not excluded that some high-density sponges will be added with supersoft additives to make the sponge super soft and used for sound-absorbing cotton, sofa cushions, and soft wrapping materials. Medium and low density sponges are used as general protective materials. The degree of softness and hardness of Sponge Composite Cloth of the same density is also different.
Generally, the density of Sponge Composite Cloth for sofa cushion is about 35, and there are soft, hard, super soft and other specifications. Do mattresses are generally about 22. So-called high-density sponge is a term commonly used by salespeople when introducing products. High-density sponges are generally not used to absorb water.
High-density Sponge Composite Cloth has the characteristics of absorbing external force, delicate, soft, and comfortable. It can meet various market demands in automobile, furniture, health care, toys and other industries.
