There is general confusion in the various types of foams in mattresses, which set the market for use in home care or health are produced.
Some people are unsure how it should be done to understand the confusing information from the manufacturers. Generally used for the type of polyurethane foam and foam mattresses is the technique used is polyurethane molding. Polyurethane foams are available in both soft and hard. The softness or hardness of the basicduring the process of formation of the foam with the addition of various additives such as water is determined.
It 'important to note that this is not related to the specific gravity or density of the foam. This is usually expressed in kg/m3 kilograms per cubic meter ie. The weight of the block of foam is measured in 1 x 1 x 1 meter.
The quality of the foam is basically with its density. In other words, the foam block, which is 1 x 1 x 1 and has a density of 45 kg/m3has a mass roughly the same relative size, but with a density of 56 kg/m3.
In simpler words, the density is proportional to the quality of the foam. The lower density means lower quality and shorter life. These parameters must be kept in mind, especially when the mattresses are purchased for nursing homes and hospitals.
Visco-elastic foam mattress
Polyurethane foams are made slowly, but some special additives to give this foamSlow. Unlike some other types of foam that immediately spring back to the original foam, and when pressed, slows down the foam, this means that little by little.
Slowly as the foam visco-elastic foam mattress has the unique property that uses the shape of the body through its body temperature and weight. This also shows that the pressure is distributed evenly. This also protects the delicate parts of the body from bone and sores developing.
