EPE foams are low density, semi-rigid, closed cell foam that are generally somewhere in stiffness/compliance between Expanded polystyrene and Polyurethane. Production of EPE foams is similar to that of expanded polystyrene, but starting with PE beads. [1] Typical densities are 29 to 120 kg/m 3 (49 to 202 lb/cu yd) with the lower figure being ...
A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1] Examples include:
The company formerly known as the United States Rubber Company, now Uniroyal, is an American manufacturer of tires and other synthetic rubber-related products, as well as variety of items for military use, such as ammunition, explosives, chemical weapons and operations and maintenance activities (O&MA) at the government-owned contractor-operated facilities.

For example, Wellnest, a Los Angeles-based mental health clinic, has a school supply assistance program that isn't limited to its clients. Call the front desk at (323) 373-2400 and you'll be put ...
The LAPD used 40-millimeter launchers — which fire foam projectiles at more than 200 mph — in at least nine cases that involved firearms last year, a report says. ... Los Angeles police ...
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
D3O is the namesake ingredient brand of British company D3O Lab, specializing in rate-sensitive impact protection technologies. [1]The brand comprises more than 30 technologies and materials, including set foams, formable foams, set elastomers, and formable elastomers.
This would produce flow rates from a typical 1-3/4" inch hose of 120 US gal (450 L) per minute of foam solution and 60 cu ft (1.7 m 3) per minute of compressed air. This air to foam solution ratio produces a wet, quick draining finished foam that will quickly knockdown flame and reduce fire compartment temperature.
