What's memory foam?

Memory foam is a polyurethane foam with slow rebound characteristics. It was originally designed by NASA's Ames Research Center to relieve astronauts of the tremendous stress they bear during the cosmic acceleration of a spacecraft. The Ames Research Center licensed two European companies in the 1990s to introduce the development into the civilian sector, first in medicine and later into household products.

When the flat surface of the memory sponge is pressed by the hand, a handprint will appear, and then slowly disappear, which is the signature effect of the memory sponge - "slow rebound", and other materials are difficult to imitate the slow speed of its rebound.The feel of the memory sponge is soft. When you hold the memory sponge in your hand, you will feel that the palm of your hand is constantly empty, such as the sand glass is empty, there is no rising force, and the kneading time is long and not too tired. When lying on the memory sponge mat, you will feel the gradual settling process, like sinking into a mire, and hear the subtle sound of gas flowing in the memory sponge; When people sit on the memory sponge waist pad, it is constantly deformed at first, and then it is the disappearance of the resistance feeling, and the waist pain that should have appeared after sitting for a long time, and it is difficult to find.

(1) In absorbing impact force, reducing vibration, low rebound release and other mechanical aspects, the performance is leading; It is the buffer material that protects the astronaut body 》when the space capsule lands, and it is the best material for the packaging of valuable instruments.

(2) Provide uniform surface pressure distribution; Through stress relaxation to adapt to the external pressure of the surface shape, so that the highest pressure to the lowest, so as to avoid the microcirculation of the parts of the pressure, is a long-term bed effectively avoid bedsore cushion material, can also gently maintain the shape of foreign objects, is a good material for posture pad.

(3) Molecular stability, and human contact non-toxic side effects, no allergies, no volatile irritants, good flame retardant effect and other chemical properties are reliable; No country has declared that it does not meet the health and safety testing requirements for household products.

(4) The permeable hole structure, without drilling, also ensures the air permeability and moisture absorption required by human skin, and has appropriate thermal insulation performance; It feels warmer in winter and noticeably cooler in summer than regular sponges.

(5) antibacterial, anti-mite and anti-corrosion, strong adsorption capacity, and maintain the cleanliness of the outside world; General contact with the human body, can be used for a long time without cleaning, without exposure to sunlight disinfection.

(6) Relatively durable, performance to maintain a long time; Can be shaped as desired; Can be made according to the required hardness, rebound speed, density, to meet the needs of different uses of products; Human contact feels very comfortable, etc.
