Foam Fabricating Companies List
The term “foam fabricating” can also be used to describe the types of foam and the various uses and products that can be made from them.
Foam fabrication creates products and materials that provide services like insulation, sealing, liquid absorption, vibration dampening, cushioning, protecting, soundproofing, filtering and providing structure.
Fabricated foam is used across a wide range of industries, such as furniture, electronics, automotive, construction, healthcare, household, acoustics, and filtration. It is also used on oil rigs, satellites, and in weather balloons.
Foam fabricating services create a variety of foam types for a multitude of applications.
Open cell foams are flexible foam products with cells that permit air flow.
Closed-cell foams have dense cells that are isolated from one another. They do not permit air flow.
Acoustic foams are attenuated or non-attenuated flexible foams that absorb or shape sound, respectively.
Packaging foams are any foams used for product packaging and shipping.
Bonded foams are foam products that are made when fabricators glue shredded foam or foam particles together into a block. Bonded foams are most often used as carpet cushioning.
Flexible foams have a certain amount of give and are usually used in bedding and furniture.
Adhesive-backed foams allow users to hold foam padding in place. It also maintains steady, uniform pressure. Adhesive-backed foams are popular in medicine.
Cushion foams provide cushion to both furniture and athletic gear.
Molded foam is cellular foam that maintains its shape. If it has enough give to compress with pressure, it will return to its original mold shape when you remove the pressure.
Rigid foam is moisture resistant and heat resistant closed-cell foam.
Products Made from Foam Products
Examples of products made from polyurethane foam include insulated containers, flexible foam seating, protective foam padding, insulation foam, EKG pads, x-ray positioning pads, and surgical scrubbers.
Examples of polyethylene foam products include bracing and cushioning material. Material like this is used in handling, packaging and shipping items such as clothing, food, sporting goods, signs, furniture, and computer parts.
Examples of other foam fabricated products include gaskets, pillar stuffers, couch cushions, insulation, padding foam in slippers, sponges, insulation foam, mats, filters, orthopedic foam inserts, NVH seals, filter foam in AC units, memory foam mattresses, and memory foam pillows.
People began fabricating foam and foam products between the 1920s and 1930s, after they learned how to fabricate latex foam. The first two methods for creating polymeric foams were the Talalay process and the Dunlop process. The Talalay process was originally developed in the 1930s by the Talalay brothers, Joseph, Leon, and Anselm. Joseph Talalay later went on to form Vita Talalay, a company based in the Netherlands, with plants in the US, UK, and Canada. The Dunlop process was patented by Dunlop Rubber Company in 1929.
With these developments, companies around the world were free to pursue the creation of rubber foams for an ever-expanding list of applications. Part of the reason the foam fabrication applications spread so rapidly in the mid-20th century is the fact that, spurred on by demand during WWII, scientists were discovering and developing new rubber materials and chemicals every day. In 1947, for example, researchers at Dow Chemical invented Styrofoam, or foamed polystyrene.
Today, fabricators continue to fabricate foam for all kinds of applications. In recent years, they have made a number of breakthroughs, including the development of nanocellular polymer foams. One of the most pertinent focuses of our time is sustainability. To combat the potential environmental impact fabricating processes and foam scrap can create, fabricators have turned away from burning scrap and now reuse it or recycle it.
Fabricators can use a variety of materials to make foam. These include plastic, rubbers, and low-density elastomers like polyurethane, polyethylene, cross-linked polyethylene, polyether, PVC, and expanded polystyrene (ESP).
Plastics make foams with tiny, well-dispersed gas bubbles. Plastic foam is light with a high strength-to-weight ratio.
Polyurethane foam is the most commonly used. It is a durable closed-cell foam that can biodegrade in both indirect and direct sunlight.
Polyethylene is the most common foam fabricating material. Polyethylene foam is flexible, shock-absorbent, vibration dampening, and insulative. Fabricators extrude the expanded, closed-cell plastic foam mostly as a protective material.
One particular type of polyethylene foam is known as Ethafoam, which has exceptional shock absorption qualities.
Cross-linked polyethylene, or XLPE, is chemically and physically resistant. As a foam, it is smooth, thick and extremely fine celled.
Polyether foam is a low cost closed-cell foam with adequate acoustic and packaging properties.
PVC, or vinyl is self-extinguishing, moisture resistant and rot-proof. It creates a soft, pliable and closed-cell foam that bonds well with adhesives. It is used in gaskets in order to prevent water transmission.
Expanded polystyrene, or EPS, is used for diverse applications such as padding foam in slippers, insulation foam, oil rigs, filter foam in AC units, satellites, and weather balloons.
1. Making the Foam
Fabricators typically form the foam by mixing polymers with a gassing agent and other chemicals. When they add the gassing agent, the material expands, forming a foam strip that is made up of countless gas bubbles within the material.
2. Forming the Foam Product
After making the foam, fabricators can put it through a variety of foam fabricating services such as foam cutting, die cutting, waterjet cutting, thermoforming, and foam felting.
Die cutting involves cutting different shapes out of foam strips, sheets, or blocks.
Water jet cutting fundamentally performs the same function but utilizes a high-pressure stream of water and is capable of cutting with more precision than die cutting.
Thermoforming is the most popular foam forming method. During this process, fabricators make machining shapes by heating the bulk foam materials.
Foam felting is another foam forming process during which fabricators compress and cure thick, soft foam materials in order to form denser foam materials.
3. Disposing Scrap
Certain parts of the foam fabrication process produce a lot of scrap, including during the die cutting process. During die cutting, foam scrap can be the result of changes in the converting process, the shutdown and startup of the production line or the material left over when shapes are die cutted. In addition, scrap happens when the useful life of foam products has expired.
So, after the foam fabricating process is done, fabricators need to dispose of the scrap. The preferred way to do this is via recycling.
Another way to dispose of foam scrap would be to burn it. However, this method has decreased in popularity over the past few decades. Although the U.S. government generally considers the burning of foam to be non-toxic, the increase of environmental concerns and stricter regulations regarding carbon dioxide emission have influenced companies to handle foam waste by way of recycling.
When getting ready to fabricate a foam product, fabricators consider variables such as the type of material they will use, the fabricating processes they will use, product shape, product thickness, and standard requirements. One of the big decisions they make is whether they will create your product from closed-cell foam or open-cell foam.
Closed-cell foams contain foam cells which are sealed and separate from one another, or “closed.” Closed-cell foam has a high compressive strength and a high density. The cells expand when exposed to heated gas because the cells do not break, and liquid and gas molecules cannot freely travel from cell to cell. Since the expansion in the material is filled, closed-cell foam is an ideal material to use as a heat insulator.
Open-cell foam is lighter in weight, spongy, and soft. The surfaces of the bubbles, or the cell walls, are broken, and all the spaces in the material are filled with air. The soft, weak nature of open-cell foam makes the material ideal for foam cushions and foam padding. Open-cell foam is also twice as resistant to sound as its closed-cell counterpart and can thus be used as an effective sound barrier.
To make your product work better for you, foam fabricators can create a variety of custom foam products. To make custom products, fabricators use custom molds, custom materials, unique colors, and unique shapes and sizes. Learn more about what custom foam options particular foam fabricators offers by talking it over with a member of their staff.
Foam fabricating is an advantageous process for a number of reasons. First, it is versatile. With it, fabricators can make foams with a vast array of qualities, from extreme stiffness to extreme pliability. In addition, foam fabricated parts are typically more lightweight than comparable products made via other forming processes. This is especially advantageous to customers with applications that benefit from lightweight parts, such as car fabricating. Another great thing about foam fabricating is the fact that it yields such good insulators, no matter the application. This is a huge benefit for applications related to acoustics, vibration or thermal insulation. Next, foam fabricating is economical, especially if you’re looking for products in bulk. This is true two times over, since fabricators can make use of scrap foam. Scrap foam can be rebounded, shredded, and reused for products such as carpet padding, or filler for pillows and other furniture. Recycling enables foam fabricating companies to recuperate the return on their investment, which would otherwise be lost if the scrap is burned.
