Visco memory foam health hazards.

The temperature sensitive memory foam was initially referred to as slow spring back foam. It is simply difficult to measure. 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. This is because of its design to prevent serious injury to humans.

A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam. As it is memory foam is an excellent shock absorbing material. The structure of memory foam displaces under pressure or applied force. 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. 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. Most called it temper 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. The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance.
