< br/> This material is foamed and molded with polyether, like foamed bread. It can be foamed by mechanical equipment or manually surrounded by wooden boards. The foamed cotton is like a square loaf. Use a slicing machine to go through the slicing process and cut the thickness according to different requirements. The softness and hardness of the foamed cotton can also be adjusted. . Seat cotton generally adopts a density of ~/cubic meter, while others adopt a density of ~/cubic meter. Although the hardness and density of sponges are directly related, they are also related to different additive formulas. Therefore, the industry is divided into high elasticity, gray super, black gray super, and soft cotton. When designing and using products, reasonable and scientific combinations should be made based on different shapes and structures. Generally, the upper, middle and lower parts are matched with sponges of different elasticities and densities. There is a type of sponge material called fireproof cotton (flame-retardant cotton). In fact, before the sponge is foamed, fire retardant agents, such as chlorine and bromine, are added to the material formula so that when the sponge catches fire, it can produce fire-extinguishing smoke and act as a fire retardant. combustion effect.
