   There are many kinds of imported sponges, including foamed cotton, rubber cotton and so on. According to different needs, different kinds of imported sponges can be selected. Mouth sponge, let's briefly introduce some imported sponges.

一 发泡棉

       This kind of material is made of polyether foam, which looks like foamed bread. We can use mechanical equipment to foam. Artificial boards can be used to surround the foam so that the foamed cotton is like a square loaf of bread, which is then passed by a slicer. Slicing process, according to different requirements to cut thickness, and foamed cotton can also adjust the softness and hardness appropriately. And cotton is usually used. 25-28kg/m3 was used, while the other density was 20-22kg/m3.

 

 

    "Although there is a direct relationship between the softness, hardness and density of sponge, it is also related to different additive formulations. It is related, so the industry can be roughly divided into high elasticity, black grey excess, grey excess and soft cotton. The product can be seen as far as possible when it is designed and used. Different shapes and structures should be rationally and scientifically matched.   

nbsp;   ;This material cotton is made of polyurethane, which is mixed with various additives such as foaming agent, while the pressing agent is heated by simple mould. Can press out different shapes of sponge, it is very suitable for swivel chair sofa cushion, back cotton, but also a small number of handrails can use stereotyped cotton. Do it.

nbsp;   One of the sponges, it is mainly made of natural latex collagen, which has the characteristics of rubber and high elasticity. Good, no deformation, good resilience, but because its price is not expensive, than foamed cotton is 3 to 4 times higher.
