Manufacturing Process of Memory Foam

!±8± Manufacturing Process of Memory Foam

Memory foam is a mixture of chemical compounds. It is primarily made of polyurethane with combination of other chemicals. The combination of chemicals with polyurethane varies with the manufacturers. The formulation of memory foam has been copyrighted and maintained as a trade secret by the manufacturers. This is due to the fact that different combinations of chemicals with polyurethane deliver different viscoelasticity and density of memory foam. One of the chemicals used with polyurethane is silicone additives.

The main constituent of memory foam is polyurethane. They are chemical substances with linear polymers which are made of carbamate groups (-NHCO2). These groups are called urethane, formed by the chemical reaction between a polyol and a diisocyanate. Polyol is a multiple hydroxyl group bearing alcohol and diisocyanate has two isocyanate groups. Isocyanate is a functional group with a single nitrogen, carbon and oxygen molecule. The ratio of polyol and diisocyanate used for the process is 1:2. When these compounds react with water, in the presence of catalysts like tin and amines, it forms cells which are very similar to bubbles. The size of the bubbles is controlled by surfactants, which lowers the liquid surface tension.

This reaction is an exothermic reaction and the product formed is a liquid. The liquid is then dispensed into a mold, where it expands. The expansion of the liquid is like dough and hence the liquid is called as a 'bun'. The expanded liquid dries up to form the foam or polyurethane. This polyurethane when combined with other chemicals, which are trade secrets, produces the foam of varying densities and elastic properties. After combining other chemicals with polyurethane, the mixture is allowed to dry. Then it is cut or clipped into the desirable sizes for its variety of use. The entire reaction takes about 5 minutes.

As the chemical composition of the foam is mainly polyurethane, it is combustible. If the foam gets ignited accidently, it can spread the flame rapidly and also emits toxic gases. Hence some of the manufacturers in America treat them with flame retardants like Polybrominated diphenyl ethers (PBDE). Some of the studies of PBDE have shown that they are causes for the impairment of nervous and reproductive systems in animals. Memory foam keeps away the dust mites and mildew due to its chemical composition, as these mites feed on natural fibers like cotton.

There are misconceptions that the foam contains residues of diisocyante. Diisocyanate is completely consumed in the polymerization reaction with polyol. So any product made of genuine memory foam will not contain residues of diisocyanate. There are replicas of memory foam made of cheaper constituents, which may be hazardous. Some of the manufacturers who make genuine memory foam include Tempur-Pedic, ECO-CELL, Dynamic Systems, SunMate and Pudgee.

How does memory foam work and why should you worry? This amazing foam developed by NASA in 1960. They wanted a better seat cushions for astronauts. Twenty years later, memory foam can be madeTEMPUR. These days there are tons of companies to choose from. The foam works as follows: to compress the small cells in the foam, if you print on them. Unlike regular foam, "remember" and remain compressed. Regular foam is elastic and dry. He pulls on you if you sit there with your bare skin. It is not elastic and it feels like rain tires, though. It feels a bit 'sticky foam is normal, but the story is different, non-abrasive way.

The memory foam cells flattenin response to your body weight and heat. But they work independently. For example, if you put your hand on it, with fingers open, the foam compresses only where you actually touch. This is incredible news for people with back pain. The foam dissipates pressure points by supporting only those areas in contact with the bed.

Dollars & sense
Now you know how it works, why there is a cost-effective, too. You can spend $ 500 to thousandsDollars for a new mattress. What if I told you that you spend $ 200 and have an experience you sleep better? This is the miracle of memory foam. A shot is a good choice.

There will be a while ', probably a year, and you will notice a difference in your sleeping bag. The reason I say thatlast year that a cost-toppers so it is probably only an inch or so thick foam and the same will be easy. The thicker the foam topper and memory, the heavier the better. This is as expected - it costs you more money. The thicker and heavier, the most expensive because the company to use more materials, which had been to create the foam.
