Memory sponge

Memory sponge, chemically called polyether type "polyurethane" foam sponge, commonly known in English as MEMORY FOAM, has the mechanical properties of slow rebound, impact absorption, vibration reduction, low rebound, air permeability, moisture absorption and other properties, and soft foot feel, The chemical properties of MEMORY FOAM are reliable, including stable molecules, non-toxic and side effects when in contact with the human body, no allergies, no volatile irritating substances, and good flame retardant effect, The memory foam currently produced is 1.5CM thick and has a density of 38D.

The difference between memory sponge and ordinary sponge:

1. Memory cotton has many different characteristics compared to sponge.
2. Sponges only have elasticity. Lighter in weight than memory foam, with material costs much lower than memory foam
3. Memory cotton is not only elastic, but also sticky, making it a viscoelastic material.
4. Memory cotton, also known as slow rebound space cotton, 3D cotton, or elastic cotton, is because it slowly returns to its original shape when subjected to force.
5. And the sponge immediately restores its original shape. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers.
