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 ...
An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
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 ...
The most common RIM processable material is polyurethane (known generally as PU-RIM), [2] but others include polyureas, polyisocyanurates, polyesters, polyphenols, polyepoxides, and nylon 6. For polyurethane one component of the mixture is polyisocyanate and the other component is a blend of polyol, surfactant, catalyst, and blowing agent. [1]
Before the 1950s, body solder was often used to repair large imperfections prior to painting [6] in both new cars and vehicle repair shops. [6] Solder repairs were conducted using a flame and wooden paddles covered in tallow or motor oil, which prevented the half-molten lead from sticking.
Robert A. Volz is credited with discovering the first process for making reticulated polyurethane foam in 1956 while working for the Scott Paper Company. [6] Production of reticulated polyurethane foam is a two-step process that begins with the creation of conventional (closed-cell) polyurethane foam, after which cell faces (or "windows") are removed.
Upholsterers may be called upon to repair or replace seating, cushions, cabin furnishings, headliners, and boat carpeting. Marine upholstery, in particular, requires special considerations due to the harsh marine environment. Factors such as dampness, sunlight, and hard usage must be taken into account. Many sources now offer marine-grade vinyl ...
Paintless dent repair can be a very beneficial repair given that the damage qualifies. It can save the factory finish of a vehicle which cannot be replicated nor reproduced. However, PDR does not replace a traditional body repair shop. Factors such as paint damage, stretched metal or an already re-painted panel can inhibit the success of a PDR ...
