Visco Memory Foam Health Hazards

A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam.

Visco memory foam health hazards.

As it is memory foam is an excellent shock absorbing material. It is simply difficult to measure. It offers safety in helmets pads and plenty of other equipment. The structure of memory foam displaces under pressure or applied force.

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. Memory foam was developed in 1966 under a contract by nasa s ames research center to improve the safety of aircraft cushions. 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.

It is a blend of polyurethane foam that was developed for airplane cushions by a nasa contract in the 1970s. The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance. 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. The temperature sensitive memory foam was initially referred to as slow spring back foam.

Visco elastic foam is another term for memory foam. Its primary function was to keep astronauts safe during missions in space.
