What are the four major categories of sponge?

In our daily life we will encounter a lot of packaging lining made of sponge, cellulose sponge manufacturerbut people for the sponge of the four major categories may not be very clear? Xiao Xiao on this issue, the next to take you to understand the four major categories of sponge which are?

1, stereotyped cotton

This material cotton by polyamino acid through the material, wholesale Konjac spongeby foaming agent and other food additives to mix, press agent into a simple design mold heating system can be pressed out of many different structural shapes of the sponge, it is suitable for swivel chairs sofa cushions, back cotton, but also a small number of handrails are also made with the stereotypes of cotton. At present, natural luffa spongethe use of 55 # ~ 60 # material with density, its elasticity is more in line with the relevant technical standards of enterprises.

Sponge elastic hardness can be adjusted according to the different parts of the product. General block cotton hardness is higher, density, back to the cotton more times

The pillow cotton is softer.

2, foam cotton

This material is foamed with polyether, like foamed bread. Foam can be used mechanical equipment, you can also use artificial board. Foam cotton is like a square piece of bread. After slicing with a slicer, the thickness can be cut according to different requirements, and the softness of the foam can also be adjusted. Generally 25~28kgu002Fm5 is used for cotton sizing, and 20~22kgu002Fm3 is used for others.

Sponge soft hardness and density, although there is a direct impact on the relationship, but with different additives formulations also have a social relationship, so the business industry is divided into high elasticity, gray super, black and gray super, soft cotton. Product innovation design use should be depending on different modeling, structural issues for a reasonable use of science and technology with, generally divided into the upper, middle and lower three main parts with the way different needs elasticity, density of the sponge.

There is a foam material called foam fire, in fact, foam fire before adding flame retardant materials, such as chlorine, bromine, etc., so that the foam fire smoke, play a role in flame retardant.

3, rubber cotton

A sponge, natural latex as the main material foamed. With rubber characteristics, excellent elasticity, good resilience, no deformation, but expensive, 3 to 4 times higher than the foamed cotton.

The above three cotton prices from high to low order: rubberized cotton, foam cotton, foam cotton

4, recycled cotton

There is a furniture product called "recycled cotton", in fact, is extruded from the sponge trimmings. The cost is very low, but the elasticity is very poor, the density is not the same.
