PU sponge has high density, stronger liquid absorption, more tough and elastic foam, good wear resistance, will not scratch the wiped device, will not drop chips.Widely used in electronic appliances, lighting, arts and crafts, glass, ceramics, home appliances, furniture, hardware products, toys, daily necessities and other products. Due to the hydrophilic nature of the molecular structure, it has a strong ability to absorb water. And crisscross micro pores produce capillary phenomenon, play a superior water absorption performance. A contact with water, high speed adsorption, stored in the cotton body, the general water absorption rate of its own weight 8-10 times. The quality of PU sponge is not very heavy, and the physical strength of tensile is very excellent. Its chemical stability is very good. According to the density, hardness and color classification, the type is very complete, can be used in all kinds of secondary processing and combination, can choose a very wide range.…
