Who Invented Memory Foam?

While these foams contain chemicals which make the surface of the foam feel cooler, many experience the same heat issues with gel foam. Proteins, because they are edible, find wide use as foaming agents in foodstuffs such as whipped cream, marshmallow (made from gelatin and sugar), and meringue (from egg white). The foam used to combat oil fires consists of bubbles of carbon dioxide (liberated from sodium bicarbonate and aluminum sulfate) stabilized by dried blood, glue, or other cheap protein-containing materials. Beer foam is believed to be stabilized by the colloidal constituents present, which include proteins and carbohydrates.

The vulcanization process cross links latex particles with sulfur through the application of heat and accelerators such as zinc oxide. Standard Polyethylene foam can be heat treated to reduce foam particulates. The heat melts the open air pockets and creates a shiny smooth surface that helps reduce particulation. This will add some labor to the cost of the foam interior but is a less expensive option than using cross link foam. There are also some small cell options of PE foams available, like SoftFoam that mimics some of the properties of Crosslink without the high cost.

How do you make a lot of foam?

Class A Foam is specially formulated to make water more effective for firefighting. The surfactants in Class A foam significantly reduce water's surface tension and, when mixed with air, create a superior foam blanket that surrounds fuels with a thick layer of water.

A number of things can get introduced into hot tub water when we soak. Hair conditioners, detergents, makeup, lotions, sweat…all these things can end up in your hot tub while soaking. The concept, which is supported by laboratory evidence, is that during the sequential or coinjection mode, foam will form in situ in the matrix reservoir rock. Supporting this contention is the expectation that low-viscosity and high-mobility gas will tend to finger into the aqueous foaming solution and generate the foam in situ. That is, the horizontal differential pressure gradient vs. vertical differential pressure gradient that the foam will experience during its flow and/or placement in the reservoir needs to be evaluated.

What are Foam Density Ratings?

Chemguard does recommend a compatibility study to be made to determine the quality of the concentrate with which the Chemguard concentrate is to be mixed. AFFFs that are manufactured to the latest revision of Mil-F specification are mutually compatible by definition.

What is foam concentrate?

FOAM: A fire fighting foam is simply a stable mass of small air-filled bubbles, which have a lower density than oil, gasoline or water. Foam is made up of three ingredients - water, foam concentrate and air. When mixed in the correct proportions, these three ingredients form a homogeneous foam blanket.

Before reviewing the merits of the different types of foam concentrates, there are certain terminologies associated with foam that must be understood. If the above are correct, you likely do have a foam issue.

Foamy hot tub water? Clean it up!

Foam is described as open cell foam or closed cell foam depending on the arrangement of the material cells. Closed cell foam is made up of sealed and unbroken cells or bubbles that are in a tight configuration resulting in dense foam that provides a strong surface. The market for flexible foam will continue to expand into nontraditional areas, such as shock absorption, acoustical applications, and toys. This will require improvements in material properties and processes, as well as the development of new chemicals to meet the demands of new applications for other types of foams.

Foam description

The amount is normally shown on the pail or drum of concentrate. The container will normally display a figure or combination of figures. Normal figures shown are 1%, 2%, 3% or 6% or a combination of 1% and 3%, 3% and 3%, or 3% and 6%. If the container of foam concentrate has 3% shown, it means that for every 100 gallons of foam solution required, 3 gallons of the foam concentrate must be used in the solution with the balance being 97 gallons of water.

The backscattering intensity is directly proportional to the size and volume fraction of the dispersed phase. Therefore, local changes in concentration (drainage, syneresis) and global changes in size (ripening, coalescence) are detected and monitored. Being a multiscale system involving many phenomena, and a versatile medium, foam can be studied using many different techniques.

Foam scales and properties

There are a lot of very inexpensive, low density memory foam toppers which are sold online. Many mattresses also contain this low density, inexpensive memory foam. Low density memory foam may work well for a few months after purchase, but it will degrade very quickly. Polyurethane foam rarely carries any emission certifications other than the certipur-US certification. This certification is often touted by mattress manufacturers.

Foam description
  • Observations of the global structure can be done using neutron scattering.
  • Rigid foams are highly cross-linked polymers with a closed cell structure that prevents gas movement.
  • Low density gas-blocking foam helps favorable placement around such problem wells.
  • Syntactic foams are also used in space and deep-sea exploration.

Is foam a colloid?

Foams are made by forming gas bubbles in a plastic mixture, with the use of a blowing agent. Foam manufacture is either a continuous process for making laminate or slabstock or a batch process for making various shapes by cutting or molding. There are two basic types of foam.

Foam description

Most of the time this interface is stabilized by a layer of amphiphilic structure, often made of surfactants, particles (Pickering emulsion), or more complex associations. This article is about the substance formed from trapped gas bubbles. Open cell foam is more flexible as the cells of the material are broken, or open.

Is Polystyrene an element?

Polystyrene breaks down so slowly that it is not viable as a biodegradable product. Most of the polystyrene that ends up in landfills will still be there 500 years from now, according to the Environmental Action Association.

Because of its dense foam core, we feel that it should work well with most body weights without the risk of bottoming out. It also could be an excellent solution for light sleepers who are easily disturbed by motion, as it has a great level of motion isolation. The Mint features two layers of open-cell T&N Adaptive® foam that should gently cradle the body while relieving pressure.

Weigh accurately 5 g of shampoo product and 145 g of water into a blender. shows typical air contents and specific volumes of a selection of aerated food products. are usually applied to transient food foams such as beer and wine foams and beaten egg whites. Foamability and foam stability are often inversely related – a greater foam volume is achieved at the expense of a less stable foam.

2 depicts a surfactant molecule residing at an oil/water interface. Because solid foams are light and compressible, they make an excellent stuffing and packing material. Solid foams may be used to engineer strong yet light materials. Foams are stabilized by the Marangoni effect and by van der Waals forces. The Marangoni effect is a mass transfer along the interface between fluids due to surface tension gradient.

Foam rubber is found in a wide range of applications, from cushioning in automobile seats and furniture to insulation in walls and appliances to soles and heels in footwear. Foams are made by forming gas bubbles in a plastic mixture, with the use of a blowing agent.

Is Class A foam corrosive?

Toxic chemicals in memory foam. Some memory foam mattresses contain toxic chemicals such as formaldehyde, benzene, and naphthalene. Memory foam may contain isocyanates, which, according to the Occupational Safety and Health Administration, can cause irritation of the eyes, nose, throat, and skin.

FFFP concentrates do not have the quick knockdown of the AFFF’s when used on a spill fire such as an aircraft crash or a highway spill. When used on fuel in depth fires they do not have the burn back resistance of fluoroprotein. FFFP foam can be generated with either air-aspirating or non air-aspirating nozzles.


If 6% were displayed, this would mean that 6 gallons of the foam concentrate would be required to be mixed with 94 gallons of water to form the 100 gallons of foam solution. From the above, it becomes obvious that a 3% foam concentrate is twice as concentrated as a 6% foam concentrate. On the same size and type of flammable liquid fire, half as much 3% foam concentrate would be required than if the 6% foam concentrate had been used.

While it provides a pinpointed feel, it is not as supportive as latex foam. We commonly talk to people who have a memory foam mattress or topper but cannot stand the unsupportive, sinking feeling they experience on it. Covering memory foam is actually one of the top reasons that people buy our mattress toppers. Unlike latex foam, which responds instantly and provides constant support, memory foam responds slowly and sinks further the longer that pressure is applied to it.
