Sponge rubber manufacturers tell you what role it has:
Because of the different application habits, the meaning of "sponge rubber" in China's high-tech references has not yet distinguished the perforation of bubbles from the organization of the omental sac. Sponge rubber has a complete range of varieties and various classification methods: 1.7.1. Classification of cell tissues: vulcanized rubber of omental capsule microplate and vulcanized rubber of perforated microplate; 1.7.2. Classification of polyurethane foaming multiple: low polyurethane foaming (apparent density ≥ 0.5G/portal-saas/new2023082119223596543/CMS/image/" />
Such as: ① the apparent density is small, light material province.
② rich ductility and flexibility, with excellent anti-fouling, moisture and other sealing effect.
③ Improve the heat insulation characteristics, with a lower heat transfer coefficient.
④ Improve the ability to digest and absorb impact loads, and have high-quality buffer shock absorption characteristics.
⑤ Improve the actual effect of sound insulation, noise reduction and sound insulation.
The improved feel, enhance comfort.
⑦ The scope of technological performance change is large, and the relative characteristics of sponge rubber can be obtained by changing the apparent density or cell structure.
Therefore, sponge rubber products are widely used in many aspects, such as sealing, shock absorption, heat insulation, sound insulation and noise reduction, printing and dyeing plants and even ion exchange method, and are widely used in airlines, cars, instruments and equipment, instrument panels, household appliances and packaging industrial production. Its appearance design has plate, strip, tube, roller, seal ring, etc., specifications and models of various shapes. Different application standards, there are different hole structure and diameter specifications. The sponge factory is required to make relative adjustments in the secret recipe design and production process to achieve relative performance indicators.

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.
