The Characteristics Of Memory Foam (Slow Rebound Foam)

17 . Nov . 2023

Memory foam overview:

Memory foam is a polyether polyurethane foam sponge with slow rebound mechanical properties. It is a special sponge developed by a European company. The common English name is MEMORY FOAM, and memory foam is its literal translation. In China, it is also called slow rebound sponge, zero pressure sponge, aerospace cotton, TEMPUR material, low rebound sponge, viscoelastic sponge, slow elastic sponge, inert sponge, etc. .

Memory foam is a polyurethane foam with slow rebound properties. It was originally designed by NASA’s Ames Research Center to relieve astronauts from the enormous stress that astronauts put on during the spacecraft’s cosmic acceleration. Ames Research Center authorized a European company in the 1890s to develop and introduce it into the civilian category twice, in medicine, and later into household products. After being widely recognized abroad, it has appeared in China in the past 10 years.

Memory foam application:

Due to the difficulty and high cost of production, the main application of memory foam is to protect the human body, and it can be found in modern equipment and expensive products. For example, in the fields of extremely high-speed aerospace and aviation, it exerts its ability to absorb kinetic energy and shock; in static environments, such as sleep, sitting, etc., its deformation is required to balance the contact pressure of the weight-bearing surface and maintain the blood circulation of soft tissues. Desired low pressure environment; provides gentle support in a postural maintenance environment.

The promotion rate of memory foam is proportional to the consumption capacity of a country/region. The application of memory foam is very popular in developed countries, and it is just beginning in developing countries. In China, the proportion of consumer goods in developed coastal cities is relatively high. Among the applied products, memory foam pillows are one of the to be promoted.

Memory foam features:

* In terms of mechanics, such as absorbing impact force, reducing vibration, and releasing low rebound force, it is a buffer material to protect the astronaut’s body when the space capsule is landing, and it is a material for the packaging of valuable instruments.

* Provides uniform surface pressure distribution; adapts to the surface shape of external pressure through stress relaxation, so that the pressure at high points is reduced to a low level, thereby avoiding parts with microcirculation pressure. Maintains the shape of foreign objects and is a good material for posture mats.

* Molecular stability, no toxic and side effects in contact with human body, no allergies, no volatile irritating substances, good flame retardant effect and other reliable chemical properties; no country has announced that it does not meet the hygiene and safety testing requirements of daily necessities.

* The transparent cell structure ensures the breathability and hygroscopicity required by human skin without perforating, and has proper thermal insulation performance; it feels warmer in winter and cooler than ordinary sponges in summer.

* It has antibacterial, anti-mite, anti-corrosion, strong adsorption capacity, and maintains the cleanliness of the outside world; generally, it can be used for a long time without cleaning or exposure to the sun when it comes into contact with the human body.

* It is more durable and maintains performance for a long time; it can be arbitrarily shaped as needed; it can be made according to the required hardness, rebound speed, and density to meet the needs of products for different purposes; the human body feels very comfortable, etc.
