Common Materials Knowledge Of Furniture-Sponge Product

- Oct 10, 2019-

(1) Styling cotton

This material is made of poly-amino acid material, mixed with various additives such as foaming agent, and pressed into a simple mold to press out different shapes of sponge. It is suitable for swivel chair cushion, back cotton, and also a small amount of handrails. Made with styling cotton. At present, the material density of 55#~60# is adopted, and its elasticity is 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 seat has higher hardness and higher density, followed by back cotton, and the cotton is softer.



(2) 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. The foam can also adjust the hardness. . The seat cotton is generally 25~28kg/m5, and the other is 20~22kg/m3 density.

Although the softness and density of sponges are directly related, they are also related to different additive formulations. Therefore, the industry is divided into high elasticity, gray super, black gray super and soft cotton. When designing the product, it should be rationally and scientifically matched according to different shapes and structures. Generally, it is divided into three parts: upper, middle and low, 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 make the sponge produce fire smoke when it is on fire, and it plays a flame retardant role.


(3) Rubber wool

One of the sponges, which is made of natural latex material, which has rubber properties, excellent elasticity, good resilience and no deformation, but it is expensive and 3~4 higher than foamed cotton. Times.

The above three cotton prices are ordered from high to low: rubber cotton, styling cotton, foamed cotton


(4) Recycled cotton

There is a kind of furniture product called "recycled cotton", in fact, it is made by crushing sponge pieces. The cost is extremely low, but the elasticity is extremely poor and the density is different.
