Materials For Industrial Sponges
Feb 04, 2026| Industrial sponges are primarily composed of polyurethane; characterized by their hydrophilicity, high toughness, and strong stability, they are well-suited for industrial applications such as wastewater filtration and oil-water separation.
Polyurethane: The most widely used base material for industrial sponges. It is produced through the reaction of polyether or polyester polyols with isocyanates, exhibiting properties such as light weight, porosity, excellent elasticity, sound absorption, and shock dampening. It is extensively utilized across sectors including furniture, automotive, and packaging.
Polyether-based Polyurethane: A specific type of polyurethane frequently used in the manufacture of standard foam and memory foam. It is distinguished by its excellent resilience and breathability.
Polyvinyl Alcohol (PVA): A highly absorbent material characterized by its lack of visible pores and its complete biodegradability. It is ideal for applications demanding high standards of cleanliness and liquid absorption-such as medical dressings and surgical sponges.
Polyester-based Polyurethane: Similar in composition to its polyether-based counterpart, yet offering superior resistance to hydrolysis and heat. This makes it particularly suitable for use in specific industrial environments.
