Zhenyue sponge products have a group of experienced professional and technical personnel and managers of engineering projects. In the competition among peers, first of all, according to the ISO9001:2008 and ISO14001: commodity raw materials are all made of new environmental protection materials, which are in line with the import and export standards of many countries. The company is a famous manufacturer of unique sponge polyurethane foam products, PU polyurethane foam products and EVA polyurethane foam products in China, technical professional product R & D, production and manufacturing are suitable for electronic devices, small toys, household furniture and daily necessities, processing technology, decoration design, packaging, corporate office fitness training, skin care products, fitness and sports health care equipment, air filtration, industrial production machinery and equipment, electrical products, Sponge manufacturers in the fields of automotive beauty decoration, health care and medical care.
The characteristics of polyester sponge: strong tensile strength, well-proportioned air outlet, high relative density, common in electronic devices, cars, printer consumables, instrumentation packaging, household appliances level, generally reduced sponge.
Sponge strength:
20-35 ° soft sponge
36-40 ° neutral sponge
41-45 ATK, hit
46-55 ° full attack (hard sponge)
56 ° ≈ superhard
Main purpose:
Because PU sponge has the characteristics of heat insulation, heat insulation, sound insulation, shock absorption, flame retardancy, antistatic, and good air permeability, it involves a variety of fields, including the automobile industry, rechargeable battery industrial production, Skin care products industry, bust size underwear processing and manufacturing and high-end furniture processing and manufacturing.
Production process:
① Polyurethane foaming epoxy resin, polyurethane foaming modifier and adhesive epoxy resin (to make the finished product adhesive) are mixed together.
② Carry out polyurethane foam production and processing. 80 parts of butadiene vinyl acetate (EVA), 20 parts of APAOPT3385, 20 parts of formamide dimethyl amide, 19 parts of CaCO and 0.6 parts of peroxide diisopropylbenzene are mixed together, polyurethane foam is placed in the mold shell, and the closed cells are defeated by mechanical equipment force, so that polyurethane foam sponge can be prepared. The relative density (d) was 0.028 g/cm, and the 25% shrinkage strength was 1.9KPa.

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.
