What are the general classification of imported sponge manufacturers:
The key to PU sponge includes polyester and methacrylate type, which can be cut into pieces or rolled, and can also be produced and processed according to customer regulations, pressed production and processing, and engineering blasting and drilling solutions. PU sponge has the characteristics of heat insulation, heat insulation, sound insulation (thus called sound insulation sponge), shock absorption, flame retardancy, antistatic, good air permeability, etc., so it involves a variety of fields, including automobile industry, rechargeable battery industry production, skin care products industry, chest size underwear processing and manufacturing industry and high-end furniture processing and manufacturing industry.
Polyurethane foam: This raw material is foamed with methacrylate polyurethane, like polyurethane foam toast. Can be used for industrial equipment polyurethane foaming can also be manually surrounded by woodworking boards polyurethane foaming, polyurethane foaming cotton is like a square piece of bread, the application of automatic slicer after cutting process, according to different provisions of drilling thin thickness, polyurethane foam cotton can also adjust the soft strength. Seat cotton generally choose 25~28kg/cubic, other selection of 20~22kg/cubic relative density. Although the soft strength and relative density of sponge are immediately related, they are also related to different preservative secret recipes. Therefore, the field is divided into high elasticity, gray super, cool gray super and soft cotton. When designing products for application, effective scientific research and matching should be carried out according to different modeling design and structure. Generally, sponges with different ductility and relative density should be matched in three positions: upper, middle and lower. There is a kind of sponge called fireproof rock wool raw materials (flame retardant sponge), is actually sponge polyurethane foam, raw material secret recipe plus fire retardant, such as chlorine, bromine when the sponge fire to cause fire smoke, with flame retardant effect.
Rubber cotton:
One kind of sponge, it uses the main material is natural latex mattress raw material polyurethane foam, it has the characteristics of vulcanized rubber, good elasticity, good resilience, not easy to deform, but the price is expensive, higher than polyurethane foam 3~4 times.

How to identify natural sponge and artificial sponge?
Compared with artificial sponges, natural sponges do not have static electricity that hurts the human body, do not peel off and last long. The sponge that lives in the sea is the real sponge, and the artificial "sponge" just imitates the structure of the natural sponge. Natural sponges that live in seawater are mostly grayish yellow, brown or black lumps. Its body surface has many bulges, there are many small holes beside the bulge, and there is a large hole at the top of the bulge. Seawater flows in from small holes and out from large holes, and those tiny creatures enter the sponge with the water and become "self-contained" food. Therefore, although the sponge is called "the flowers and fruits of the sea", it looks like a plant, but it is actually an animal.
Buy a pack of large salt or coarse salt, put the coarse salt and dirty plush toys into a larger plastic bag, and then fasten the mouth of the bag tightly and shake it vigorously. You will surely find that the plush toys are clean. The crude salt removed became gray-black due to the adsorption of dirt. The principle is the use of salt that is sodium chloride adsorption of dirt. Soda powder can also be used instead of coarse salt, the same usage. This method is more suitable for large plush toys and plush toys that can not be washed with sound.
The main ingredient of the sponge?
Polyurethane soft foam rubber, polyurethane is one of the most common polymer materials in life, widely used in the production of various "sponge" products. Now there are three kinds of sponges on the market, 1: polyurethane type, burning to generate a large number of cyano-containing gases, these gases are very toxic and suffocating. 2: polyethylene type, combustion of carbon-containing gas, this kind of gas toxicity. 3: polystyrene type, this kind of foam burning decomposition of a small amount of styrene monomer, toxic, but not as toxic as polyurethane.
