Nanosponges with different opening sizes and different textures are not necessarily a quality problem.
The current production process of nanosponges is roughly the same, and the formula of foamed nanosponges is changeable, and there are two most common ones on the market. The nanosponges produced by the two formulas have their own characteristics, not the difference in quality. Foamed nanosponges need to use a certain catalyst to change the physical properties of the raw materials under a specific temperature and humidity, thereby generating a sponge texture.
The proportion of the formula is different, the properties of the finished product will be different. Currently, there are two types of nano sponges popular in the market: one has fine foam, high elasticity, but easy to tear; the other has coarse foam, soft texture, but good toughness.
Both nano sponges have a certain position in the market, and consumers of kitchen cleaning sponges have their own preferences. However, the laboratory proved that the cleaning effect and durability of the two kinds of nano sponges are not much different. You only need to choose the nano sponge according to your preferences.More about:magic melamine sponge
