Visco Memory Foam Health Hazards

It is simply difficult to measure.

Visco memory foam health hazards.

Visco elastic foam is another term for memory foam. A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam. Created by feeding gas into a polymer matrix the foam has an open cell solid structure that matches pressure against it yet slowly springs back to. According to the epa s review of mdi and tdi completely cured products are fully reacted and therefore are considered to be inert and non toxic.

Memory foam was developed in 1966 under a contract by nasa s ames research center to improve the safety of aircraft cushions. It is a blend of polyurethane foam that was developed for airplane cushions by a nasa contract in the 1970s. Most called it temper foam. Greener versions of memory foam use plant based ingredients like soybean oil in place of some of the petroleum derivatives memory foam s distinguishing feature is that it softens in response to heat and pressure.

The polyurethane foam association an industry group as well as the environmental protection agency both say that finished memory foam is inert and does not represent a health hazard. This is because of its design to prevent serious injury to humans. As it is memory foam is an excellent shock absorbing material. The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance.

The structure of memory foam displaces under pressure or applied force. But perhaps one of the more difficult stumbling blocks to testing the health benefits of mattresses such as memory foam is the subjective nature of sleep.
