What is a Polyurethane sponge?

Polyurethane sponge is a porous material made from polyurethane resin, known for its light weight and excellent flexibility. The polyurethane resin undergoes a chemical reaction that causes it to expand into a foam structure, trapping air within, resulting in the spongy texture. This material has outstanding elasticity, durability, sound absorption, and thermal insulation properties, making it widely used across various industries. It is commonly found in furniture, bedding, car seats, building materials, and sound equipment, among others. Polyurethane sponges are also commonly used for cleaning purposes due to their light weight and water-absorbing properties. The sponge's hardness and density can be adjusted according to its intended use, making it versatile for many applications.

Application of Polyurethane sponge

１．Furniture: Used as cushioning material for sofas and mattresses.
２．Automotive: Used as inner material for seats and soundproofing components.
３．Sound Equipment: Used in sound absorption pads and soundproofing materials.
