1, this material is foamed with polyether, just like foamed bread. Foaming can be done by mechanical equipment or wood-based panels. Foam cotton is like a square piece of bread. After slicing with slicer, the thickness can be cut according to different requirements, and the hardness of foam can be adjusted.

2. Generally, cotton uses 25 ~ 28kg per cubic meter, while others use 20 ~ 22kg per cubic meter. Although the softness and hardness of foamed cotton are directly related to density, they are also related to different additive formulas, so the industry is divided into high elasticity, gray super, black gray super and soft cotton. When designing and using products, we should make reasonable and scientific collocation according to different shapes and structures.

3. Sponges with different elasticity and density are generally divided into upper, middle and lower parts. There is a material called fireproof cotton in the foam. In fact, before the foam is foamed, a flame retardant, such as chlorine and bromine, is added to the material formula, which makes the foam produce fire smoke when it catches fire and plays a flame retardant role.

Extended data:

1. Recycled sponge is a new product and a general sponge treatment method. Regenerated sponge belongs to the reuse of industrial leftovers of polyurethane products. Its use value is no less than that of sponge. It is made of industrial sponge scraps by crushing, stirring, steaming, high-temperature disinfection, deodorization and molding.

2. The production cost is greatly reduced from the use of production cost. Good elasticity, good patience, no deformation, no odor, can be made into products of various densities according to customer needs. The density of high-density and high-elasticity regenerated sponge is over 60 kg/m3, which has the characteristics of high efficiency, flame retardancy, good tension, high elasticity and no deformation. It is environmentally friendly, economical and practical after autoclaving.

3. It can be widely used to make sofas, mattresses, boss chairs, sports equipment, such as sponge gymnastics mats, sponge fitness mats, sponge wrestling mats, sponge car cushions and other products, and has been widely accepted by countries all over the world.
