Save Your Business Money with Foam Prototyping

By Carlo Badalamenti, Foam Factory, Inc. For start-up businesses, or ones trying to get through lean times on a tight budget, innovation and new products can provide a major boost. However, these carry a degree of risk that can be too much for a company with thin margins to take a gamble on. Part of this risk is because of the cost of creating a prototype of the new product, whether it's to get a bearing on the physical possibility of a new idea or for pitches to investors or...

Handi-Foam Approved for Use in Residential Houses

In the 21st century, it seems that there is a new product or invention available every day. Even the world of foam is constantly changing and expanding. The uses for Polyurethane foam and other foam types keep expanding as well as inventors and manufacturers keep creating new formulas and ways to use the foam. In August, 2012, a new polyurethane foam spray-in insulation was approved by the ICC Evaluation Service. This service monitors the safety of new insulation types and helps regulate the uses of spray-foam insulation. Many people love... Read More

Foam Fabricating: Explained

There is some misunderstanding as to what foam fabricating actually is. Many people think that foam fabricating is the process of creating the foam, but this is actually not the case. Fabricating foam includes any manipulation of the foam, whether it is simply cutting the foam into a different size or shape or merging the foam with another material to create a stronger object with different properties. Fabricating foam actually has nothing to do with manufacturing the foam pieces at all. In general, there are two forms of fabrication that... Read More

Industry Information

Foam

Foam is defined as a synthetically fabricated, polymer-based material with countless air bubbles trapped inside. It is created by frothing and cooling a molten polymer material, which creates the air bubbles and gives the material a sponge-like texture. Every type of foam shares a few characteristics with one another. These traits include light weight, low water vapor transmission, low thermal conductivity, durability, compressibility, and resistance to mildew, mold, and bacterial growth. Foam can also come in liquid form, which expands to fill gaps and other spaces in a way that solid foam cannot. Liquid foam is less common, but is nonetheless used for numerous applications such as fire retardant materials, and to prevent air and water leakage in construction projects.

Foam can be split into two general categories:

Open cell structured foam - the pores—sometimes called cells—are joined together, resulting in a foam that is softer, more flexible, and can be easily compressed and broken apart
Closed cell structured foam – the cells are closed off from one another and do not compress or join together, thus making the foam more compact in arrangement, more firm, and more resistant to pressure

Numerous industries use foam for a variety of commercial and industrial applications. A few of these applications are insulation, acoustics, packaging, structural support, and cushioning. Different foams are used for each of these applications. Foam materials can be made from a variety of synthetic polymers, including polyester, polyethylene, and polyurethane. Each of these materials have their own set of characteristics that make them the material of choice for certain applications.

Polyurethane foam is a closed cell foam that is environmentally friendly and is ideal for applications that do not require a long life span, as the material is short-lived and capable of decomposing when exposed to either direct or indirect sunlight. Polyurethane foam is highly versatile, and is commonly used in products such as lifeboats, surgical scrubbers, soundproofing, and seat cushions. It can also be used as a spray foam, which starts as a liquid and hardens after expanding and prolonged exposure to the air.

Polyethylene foam is made from mixing chemicals and adding a gassing agent, which causes the material to expand. The longer the process and the greater the intensity of the gassing agent, the more porous the foam product will be. The gas bubbles that are trapped inside the polymer make the foam flexible, unlike a solid polymer. This material is light in weight, has a high level of buoyancy, and is resistant to moisture. Because of its porous, resilient, and flexible nature, polyethylene is the ideal material for applications that require floatation, vibration and shock absorption. In addition, polyethylene foam can extend the lifespan of a product, and in turn greatly reduce maintenance costs.

When foam is stored or transported to manufacturers, the most common form it takes are stock rolls, or buns. Foam fabricators can cut the foam to match the size, shape, and configuration of the final product. Other processes that are carried out by foam fabricators include hot wire cutting, die cutting, and water jet cutting.

The field of foam fabricating is rapidly evolving, with new innovations constantly being made. Foam is a fairly new material which has only been around for several decades, although it is used for countless day-to-day applications today. Researchers are constantly looking for new ways to both fabricate and implement foam. For instance, a foam mixture was recently discovered that is low in bulk weight and high in elasticity, chemical resistance, and a high rebound performance—much higher than expanded grades of ethylene vinyl acetate, polyethylene, and polypropylene—even when only a thin layer is used. All of these characteristics makes this material ideal for cushioning products, such as the lining of shoe soles or medical grade floor cushioning.

In addition to the growth of the foam industry, other changes are being made to the way foam is fabricated. Foam manufacturers have been favoring materials and energy sources for foam fabrication that are more environmentally-friendly. Alternative materials for foam has been the subject of many research projects. There are some companies that offer biodegradable, plant-based foams. Other companies have made it a point to manufacture their products using energy from a renewable source, such as solar and wind energy. Aside from finding an alternative source, there are simpler things that large companies can be done that can reduce their carbon footprint, such as the elimination of toxins that are used in the fabrication of their products.
