Spray foam is a type of insulation that is sprayed in place through a gun. Polyurethane and isocyanate foams are applied as a two-component mixture that comes together at the tip of a gun, and forms an expanding foam. Cementitious foam is applied in a similar manner but does not expand.
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
Equipment rental was first developed in Anglo-Saxon countries. It emerged in the UK after the First World War and has now become a multi-billion euro business providing a wide range of construction and industrial equipment for customers globally.The American Rental Association was founded as early as 1955, [1] and the first waves of consolidation took place in the 1970s in North America ...

During 1955 the FB5X foam making branch pipe was introduced and the Pyrene ED-HOL system in ships, which recycled the ship's own inert exhaust gases to fight fires in the hold, was developed. Over the years Pyrene fire fighting systems were installed in a number of the world's largest passenger liners including the Queen Elizabeth , Oriana and ...
Pipe insulation made from rigid Phenolic, PIR, or PUR foam insulation is common in some countries. Rigid-foam insulation has minimal acoustic performance but can exhibit low thermal-conductivity values of 0.021 W/(m·K) or lower, allowing energy-saving legislation to be met whilst using reduced insulation thicknesses.

Other corrosive mixtures come as two-part cleaners that are mixed as they are poured in the drain opening. Inside the drain the two solutions react to release a gas, and surfactants trap the gas as dense foam. The intent of this foaming action is to coat the inside of the drain pipe to dislodge more of the substances that form the clog.
Polyethylene bead foams (including) EPE can be used to replace both polystyrene foam, and both rigid and flexible polyurethane. Uses include cushioning applications, and impact absorption applications including packaging. [4] Consumption of polyethylene for PE foam was estimated at 114x10 6 kg in 2001. The majority was used for non-crosslinked ...
