Polyurethane foam is created by mixing the raw materials polyol and isocyanate at room temperature using water.
The structure of the foam is largely determined by the structure of the polyol. The polyol can be separated into ethers and esters. It can also differ by strength, hardness, water resistance, chemical resistance, and oil resistance.
Polyurethane foam has a variety of characteristics. It has cushioning properties, heat insulation and good sound absorption. We have many different methods of processing, including making Concave/convex (zig-zag) surfaces, surface melting, and shaping.
This type of material can be seen quite frequently in day to day life. It is often used in mattresses, sofas, memory foam pillows, dishwashers, and air filters.
