Characteristics
High foam density and continuous foam, with excellent acid and alkali resistance, durability, strong water absorption, easy to clean and it is not easy to residue chemicals
In the dry state can maintain elasticity and softness, and not dry hard, no need to add water moisture resistance, strong friction, not easy to drop crumbs, tensile strength, not easy to deformation

Multi-chemical resistance is good, and it has chemical resistance to general organic solvents, and it is not easy to change when placed in acid and alkali solutions for a long time

Notes
Daily squeeze cleaning with water can increase the service life of the Sponge Roller and maintain the roundness and elasticity of the roller
