Convoluted foam is manufactured by splitting it in half and carving a ridged design. This can be done using standard polyurethane foam or viscoelastic foam. As it is commonly called, Viscoelastic or memory foam is much more comfortable than the standard polyurethane foam as it conforms to the body shape.

What is convoluted foam?
Convoluted foam made from viscoelastic foam is also known as convoluted comfort foam and is popularly used in mattress toppers to enhance comfort. How Do You Use Convoluted Foam?
How do you cut convoluted foam?
So how is it done? Amazingly enough, it’s done with a bandsaw. Egg crate, acoustic, and other shapes of “convoluted foam” are cut with a special machine called a convolutor, which uses powerful rollers to feed flat sheets of foam rubber into a high-tension bandsaw.
Is viscoelastic foam more comfortable than regular foam?
As it is commonly called, Viscoelastic or memory foam is much more comfortable than the standard polyurethane foam as it conforms to the body shape. Convoluted foam made from viscoelastic foam is also known as convoluted comfort foam and is popularly used in mattress toppers to enhance comfort.
What are the benefits of using convoluted foam mattress?
Convoluted foam is very popular with healthcare facilities. Egg-crate toppers and mattresses are used for the patients as it allows air to flow under the patient, which helps prevent bedsores and fever. The increased airflow makes them ideal for burn patients and those bedridden for a long time.
What is convoluted foam made of?
Additional Egg Crate Foam Facts Egg crate foam is made from polyurethane foam. Polyurethane is synthetically created from a chemical reaction between polyol and diisocyanate (two chemicals created from organic compounds). Once the foam is synthesized, it is hot and is poured into egg-crate shaped molds.
How convoluted foam is cut?
Convoluted cutting is similar to skiving cutting which cuts one sheet into two half pieces, and can be made with ridged designs like peaks and valleys. The convoluted cutting process begins with a large flat foam sheet that is pressed by a long roller as a blade slices it.
What is convoluted foam?
What is convoluted foam? Convoluted foam was designed as an inexpensive method of doubling foam production. By splitting the foam in half and carving points into it (like an egg crate), you get two 4 inch thick sheets of foam out of one 4 inch thick sheet of foam.
How is egg foam made?
The whisking process stretches out and unravels the proteins and they end up lining up because the hydrophilic ends are attracted to water in the egg white and the hydrophobic ends are repelled and attracted to the air in the pockets. Eventually the protein coating of the air pockets link together, making a foam.

Which type of foam mattress is best?

What is the point of egg crate foam?
Egg crate foam can be any type of foam where one side has an 'egg crate' shape. The purpose of this kind of foam is two-fold. It tends to be more responsive and distributes weight better than a thick layer of foam, and also it has cooling advantages because of the air flow that it provides.
What are the four stages of foam formation?
The polymerisation reactions associated with foam formation have distinct stages (i.e. nucleation, growth, packing, stiffening, solidification) some of which are known to be more sensitive to external inputs than others.
What is protein foaming?
Body and smoothness of food foams is related to the fonnation of air bubbles that allow volatilization of flavors with enhanced palatability of the foods. The most widely used protein foaming agents are: egg white, gelatins, casein, other milk proteins, soy proteins, and gluten.
How is foam formed in soap?
Foam is created when the surface tension of water (attraction of surface molecules toward the center, which gives a drop of water its round shape) is reduced and air is mixed in, causing bubble formulation. As one passes across a curved surface or interface, a jump in pressure occurs.

Why do people use convoluted foam toppers?
Health professionals frequently recommend convoluted foam toppers to bed-ridden patients because the shape helps prevent bedsores. Using complex cutting equipment, mattress manufacturers can turn one solid piece of foam into two pieces of convoluted foam.
Which foam provides the most cushioning and support?
Solid foam provides the most cushioning and support, whereas convoluted foam is lighter and allows for more airflow.
What is easy foam?
EASYfoam convoluted foam is a high-quality foam with excellent noise absorption values. This convoluted foam has a self-adhesive back making it very easy to apply. EASYfoam convoluted foam can in no way be compared with convoluted fo am in, for example, the construction trade that usually works with polyether foams (instead of polyester) of a low density.
Is easy foam flame extinguishing?
EASYfoam convoluted foam is flame-extinguishing according to FMVSS 302 and UL-94 class HF1. However, polyester foams and polyether foams are not suitable to be used in public spaces because of the high requirements with regard to fire resist ance in these spaces.
