Ultimately these chemicals affect two of the main qualities of memory foam.
What is memory foam mattress made of.
What is it made of.
Memory foam starts its life as polyurethane foam a material first manufactured in the 1950s by adding water halocarbons or hydrocarbons to a polyurethane mix.
Depending on the chemicals added and the way it is processed polyurethane can form anything from car parts to spray liner or in this case one of the most comfortable sleeping surfaces the world has ever seen.
Memory foam is what is known as viscoelastic polyurethane foam or low resistance polyurethane foam lrpu.
A memory foam mattress is one made from viscoelastic foam a type of high density polyurethane foam.
It s also called viscoelastic which combines two concepts.
Memory foam is a chemically produced synthetic mattress foam not too dissimilar to other foams you may have around the house.
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.
Viscosity the material moves slowly and reluctantly when pressure is applied.
It s now used in a variety of mattresses from casper simba leesa to eve.
It is both highly energy absorbent and soft.
Memory foam memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density.
Memory foam mattresses are made of polyurethane which was initially created for nasa but has since evolved into one of the most common materials used in furniture.
The foam bubbles or cells are open effectively creating a matrix through which air can move.
First designed in the mid 1960s for nasa airplane seats memory foam is made from a substance called viscoelastic.
Memory foam is polyurethane combined with some chemicals that allow it to contour to your body.
It is created by adding various compounds and additives to polyurethane which change depending on the type of foam being created.
