Visco Memory Foam Health Hazards

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

Visco memory foam health hazards.

The structure of memory foam displaces under pressure or applied force. 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. 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. 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.

The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance. Most called it temper foam. Visco elastic foam is another term for memory foam. It is simply difficult to measure.

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. 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. 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.

It offers safety in helmets pads and plenty of other equipment. The temperature sensitive memory foam was initially referred to as slow spring back foam.
