Visco Memory Foam Health Hazards

Visco elastic foam is another term for memory foam.

Visco memory foam health hazards.

It is simply difficult to measure. It is a blend of polyurethane foam that was developed for airplane cushions by a nasa contract in the 1970s. 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.

The temperature sensitive memory foam was initially referred to as slow spring back 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. Most called it temper foam. 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.

A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam. Its primary function was to keep astronauts safe during missions in space. This is because of its design to prevent serious injury to humans. Memory foam was developed in 1966 under a contract by nasa s ames research center to improve the safety of aircraft cushions.

It offers safety in helmets pads and plenty of other equipment. 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.
