With an optimum elasticity, Kymdan mattress products help to support and maintain the three natural curvatures of the spine in any laying position, and thus not causing the spine to sag.

High elasticity is a natural characteristic of natural latex (compared to synthetic latex). However, Kymdan natural latex mattresses have high elasticity allowing them to return to their original state immediately after bearing continuous compression. This outstanding feature helps prevent Kymdan mattresses from becoming sagged during its service life.

Kymdan mattress - High tensile force, high elongation at break.

 

Kymdan Mattress - does not flatten (become indented, sagged), high compressive strength, high elasticity, instantly returns to the original shape and size.

 

Shown above is a low elastic product. As seen, the product becomes flattened (indented, sagged) under high compressive strength and is incapable of instantly returning to its original shape and size (poor elasticity).

With unique technology, Kymdan products have great mechanical strength and can easily bear high and continuous pressure loads without being damaged. This feature has been tested by Kymdan Company and after being subjected to a 10-ton roller moving back-and-forth 200 times, the Kymdan mattress remained intact and undamaged. Thus, the test demonstrated the amazing sustainability of Kymdan mattresses.

The natural latex foam of Kymdan mattresses is Bacteria Resistant (following test method ISO 22196-2011) and Mold Resistant (following test method ASTM G21-15), as validated by testing conducted by Bureau Veritas, USA (Test report # (5120)274-0161).

With fire hazard being a great concern for developers and consumers of leading markets worldwide; product fire retardancy has become a vital criteria for product standards in many industries (hotels, hospitals, theaters, etc.).

Kymdan Mattresses are fire retardant. Although they can burn under extremely high temperatures, they do not ignite nor spread fire and can also help to reduce flames (meeting US standards, as tested by Bureau Veritas, USA (Test Report: (5116) 025-0070)).

Fire retardant capability of Kymdan mattresses presents as follows:

• Non-flammable to irons that are left on; as seen through our test where an iron was left on the mattress at 295oC/563oF for 60 minutes.
• Non-flammable to burning red hot charcoal; as seen through our test where a burning hot charcoal with a temperature of 1000oC/1832oC was left on the mattress for seven minutes.
• Non-flammable to welding sparks. The high temperature metal particles in welding sparks will not cause the mattress to ignite. This was seen in tests conducted where welding was performed continuously for 2 minutes; using a welding machine with an amperage of 155A; and at a distance of 10cm/3.9inches from the mattress.
• Does not ignite or cause rapid spreading of fire like other materials (e.g wool, cotton etc.) when torched with fire.

Thanks to their open foam structure, Kymdan mattresses quickly absorb water to help extinguish the fire.
