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.

Material

Polyether

  • Light, with excellent tensile strength
  • Excellent cushioning
  • Stable with water
  • Excellent chemical resistance
  • Available in a variety of hardness’s, density’s, and color’s

Polyester

  • Compared with the ether, it is stronger
  • Excellent sound absorption
  • Excellent oil, heat, and solvent resistance

High Performance
Micro-cell Foam

This high performance micro-cell foam is a high-density, very fine, urethane foam that has a uniform cell structure.
Since it has a very fine and small cell structure, it is resistant to compression (Even if you apply force, it will maintain its form).

Uses

Sealing, packing, vibration prevention, shock absorption, sports, leisure, medical applications, foot rubber, shoe insoles, etc.

Characteristics

  • Compression resistance
  • Excellent sealing properties
  • Excellent energy absorption properties
  • Contributes less to pollution than other materials
  • Excellent vibration damping properties
  • Excellent dimensional stability
  • Excellent efficiency
