Sponge types in office furniture

At present, there are many types of sponge used in office furniture on the market, such as foamed cotton, shaped cotton, and rubber cotton.

The cotton material of the styling cotton is made of poly-amino acid material, mixed with various additives such as foaming agent, and pressed into a simple mold to press out the sponge of different shapes. It is suitable for the swivel chair seat cushion, back cotton, and a small amount of handrails. Also made with styling cotton. At present, the material density of 55#-60# is adopted, and its elasticity is more in line with relevant national standards. The elastic hardness of the sponge can be adjusted and adjusted according to different parts of the product. Generally, the cotton has a higher hardness and a higher density, followed by a cotton back, and the pillow is softer.

Foamed cotton This material is molded from polyether foam, like foamed bread. It can be foamed by mechanical equipment or artificially surrounded by wood. The foamed cotton is like a square loaf. The slicer is used to cut the thickness according to different requirements. At the same time, the foamed cotton can also adjust the hardness. The seat cotton is generally 25-28kg/m3, and the other is 22kg/m3 density. Although the softness and density of sponges are directly related, they are also related to different additive formulations. Therefore, the office furniture industry is divided into high elasticity, gray super, black gray super and soft cotton. When designing and using the product, it should be rationally and scientifically matched according to different shapes and structures. Generally, it is divided into upper, middle and low parts with different elasticity and density of sponge. There is a kind of fireproof cotton material in the sponge. In fact, before the sponge is foamed, the fire retardant is added to the material formula. For example, chlorine and bromine can cause the sponge to generate smoke and fire when it is on fire.

One kind of rubber cotton sponge, which is made of natural latex material, which has rubber characteristics, excellent elasticity, good resilience and no deformation, but it is expensive and higher than foamed cotton. -4 times.
