Continuous foam separation is a chemical process closely related to foam fractionation in which foam is used to separate components of a solution when they differ in surface activity. In any solution, surface active components tend to adsorb to gas-liquid interfaces while surface inactive components stay within the bulk solution.
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
Direct injection expanded foam molding (also known as injection molded foam) is a manufacturing process that creates soft foam products direct from a compound into a final product. [1] This process eliminates the steps normally required for die-cutting and compression molding , because it manufactures the foam and the product, simultaneously.
Housed in a plastic container, the bomb has a metal partition that separates two liquid reagents. Once the partition is removed, the liquids mix and react, causing them to rapidly expand and then solidify, creating a physical barrier blocking the tunnel.
Craft-foam sheets are made of EVA and are popularly used for children's foam stickers. [clarification needed] EVA is also used in biomedical engineering applications as a drug-delivery device. The polymer is dissolved in an organic solvent (such as dichloromethane). Powdered drug and filler (typically an inert sugar) are added to the liquid ...

The reason given is: lead fails to summarise, instead presenting novel content (dispersed media, quantum foam, and allusions to foam as polydisperse, colloidal, and as suds, beer head, bath sponges, etc., all only in lead). Please help improve the lead and read the lead layout guide. (August 2024) (Learn how and when to remove this message)
