Sponge manufacturers tell you what factors affect the price of special-shaped sponge:
The strength of the special-shaped sponge is controlled by the relative density. Generally, the higher the relative density, the higher the strength, but it can be adjusted manually. High-density sponges and super-hard special-shaped sponges can loosen the special-shaped sponges with high density, improve the resilience, and also increase the strength of the special-shaped sponges with low density. Like high resilience, light and soft special-shaped sponges, special-shaped sponges that rely on manpower to adjust their strength have higher prices than special-shaped sponges with the same relative density.
③ special-shaped sponge tensile resistance, tensile resistance can be adjusted, low density special-shaped sponge general tensile resistance is small, but can be seasoning when the manual adjustment, so that its tensile resistance to improve, sometimes also affect the price.
④ Difficulty coefficient of special-shaped sponge production and processing. Production and processing procedures become more complex, or the total number of machines and equipment used, the price will be higher.
⑤ Total order information. Special-shaped sponge is made of standard polyurethane foaming. The length of polyurethane foaming at one time is about 50 meters. The more the total number of order information, the smaller the foam consumption during the middle and late production and processing. In addition, the energy consumption and labor cost of polyurethane foaming are saved, and the price is relatively cost-effective.

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.
