Difference Between Polyester Foam Polyether Foam eHow.
Polyester foam was developed first but polyether foam eventually became the better known of the two. Nevertheless they each have their strengths and weaknesses. These must be considered when deciding between these two foams. Polyether foam is typically manufactured by mixing together a collection of chemicals with water. In addition to water the mixture contains diisocyanate polyol catalysts and surfactant. As they are mixed together the foam begins to emerge. As this happens the mixture begins to rise in height. Between one and two minutes later the foam will have reached its maximum height. The final mixture should 100 parts by weight of polyether triol 40 parts tolylene diisocyanate three parts water 0.5 parts triethylenediamine 0.3 parts stannous octoate and one part silicone block copolymer.
Polyester Foam Ester Products Fabrication Polyurethane.
New England Foam stocks polyester filter foam in densities ranging from 10 PPI PPI pores per inch to 100 PPI. Traditionally polyester foam has a higher tensile strength than its polyurethane foam counterpart polyether foam. Polyester foam is also more resistant to hydrocarbons and alcohols than polyether foam. In applications where the polyurethane foam will come into contact with gases such as oxygen nitrogen and/or carbon dioxide the polyurethane foam should be manufactured with polyester-based polyols. In applications where the polyurethane foam will come into contact with a liquid-based solution the polyurethane foam should be manufactured with polyether-based polyols.

There are two types to choose between polyester polyurethane foam and polyether polyurethane foam. Put side-by-side they're virtually indistinguishable yet the differences in their properties could have a big impact on how your foam-based product performs. This blog post explains the differences and addresses why one might work better than the other. A polyester is a compound made up from multiple esters linked in various chains. An ester starts out as carboxylic acid which consists of carbon oxygen and hydrogen. Adding an alcohol which in the chemical sense means a hydrocarbon compound like ethyl replaces the hydrogen atom with a carbon-hydrogen compound.

Polyurethane Foam Wisconsin Foam Products.
They are produced under conditions with virtually no air or water discharge and minimal energy consumption. Polyester Foam Polyether Foam. Both are types of polyurethane foam. In applications where the polyurethane foam may come into contact with gases such as oxygen nitrogen or carbon dioxide a polyester-based polyurethane foam is typically used. Whereas foam applications in contact with a liquid-based solution would typically employ a polyether-based polyurethane foam. Let Our Expertise Help You! For over 25 years Wisconsin Foam Products has been providing integrated flexible foam solutions for OEMs in a broad range of industries.
Ether and Ester-Based Polyurethane Foam Characteristics Differences and Uses The Foam Factory.
This makes ether-based polyurethanes excellent for speaker foam aquarium filter media or air filter foam. Ether-based foam is also made into a special kind of foam called Dryfast foam which features an open structure to allow the flow of water and air through its form keeping it from retaining moisture and helping it dry quickly. This foam is well-suited for marine cushions in boats and outdoor patio cushioning where moisture is constantly around the products. Softer and smoother than ester-based polyurethane ether-based foams are more frequently used when a material is in greater contact with its environment. Colored polyurethane foam sheets mounted for acoustic improvement are an example of this.
Polyether Foam.
They are used in acoustic applications heat insulation sealing liquid and air filtration applications. They are demanded for their flame resistant types. They have antibacterial and antistatic types. Ease of production and cost advantages have provided a high demand for the product. Its the first preferred type of foam for all areas requiring foam use.
Reticulated foam Wikipedia.
Reticulated metal foam can also be made using polyurethane foam as a template similar to its use in ceramic foams. Metals can be vapor deposited onto the polyurethane foam and then the organic polymer burned off. Reticulated foams are used where porosity surface area low density are important.

Polyether Foam Foam Engineers.
Manufactured using a continuous process technology polyether polyols are mixed with catalysts and blowing agents which results in the foam rising freely and forming its light-weight cellular flexible structure. Polyether Foam is available in a range of densities from 10 to 60 kg/m3. The different densities are denoted by a range of pastel colours. Flame retardant additives can be introduced during the foaming process and many foams meet stringent fire test regulations and standards.
Polyether Foam Ether Products Fabrication Polyurethane.
Polyether foam's inherent comfort support and resiliency make it the clear choice for the medical apparel and sports leisure industries. Polyether foam is manufactured by mixing polyether polyols with catalysts and a blowing agent forming a free-rising foamy froth that solidifies within minutes resulting in a slabstock bun of polyether foam ready for fabrication. It is during this manufacturing process that flame retardant additives can be introduced to meet various fire code standards as well as anti-microbial anti-static conductive and/or electrostatic dissipative ESD additives. In applications where the polyurethane foam will come into contact with a liquid-based solution the polyurethane foam should be manufactured with polyether-based polyols.
