1. Water absorption: Sponges can absorb a lot of water because their porous structure can accommodate water into them. This makes sponges very useful for cleaning, wiping and absorbing liquids.

2. Flexibility: PU Roller sponge materials are usually very soft and can be bent, folded and cut as needed. This allows sponges to be used in furniture and software products such as mattresses, cushions and throw pillows.

3. Elasticity: Although sponge is soft, it also has a certain elasticity and can return to its original shape. This makes the sponge have good cushioning and shock absorption effect, which can be used to make sports shoes, car seats and other products that need to reduce impact.

4. Permeability: Due to its porous structure, sponges have good permeability and can promote air circulation. This makes sponges potentially useful in the production of ventilation materials, filters and sound insulation materials.

5. Durability: PU roller materials usually have a long service life and can withstand repeated use and cleaning. This makes sponges an affordable and environmentally friendly option that can reduce the need for disposable products.
