It can be said that packaging sponge is still very fashionable in the 21st century. Various electronic industries and other related fields are widely used in packaging sponge. Now the demand for packaging sponge will continue to rise again in the future.
②Packing sponge with high-quality physical properties: Take Ace type EVA foam plastic from Guhe Electric Company of Japan as an example. Its physical properties such as tensile compressive strength and tear compressive strength are at the maximum level of plastic foam. Its reduced compressive strength is less than that of hard PUR and polyurethane foaming Ps. Dong than soft plastic PUR Gang, that is, with a medium level of reduced compressive strength;
The packaging sponge with resilience has high impact performance and absorption.
⑤ The solvent corrosion resistance of the packaging sponge is better than all other plastic foams. Vegetable oil resistance, it is necessary to consider the sleeve greasy food packaging materials.
The packaging sponge has excellent resistance to ground stress cracking characteristics.
⑦ polyurethane foam PP in the packaging sponge and polyurethane foam PS contrast, no toxic gas release when ignited.
The packaging sponge can also be recycled.

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.
