What is polyurethane foam used for?

Polyurethane foam is a fast hardening product used in the do-it-yourself world. It is used to fill, seal or insulate holes, seams, cracks, joints and crevices in chimneys, window and door frames, pipes and pipe ducts. It easily adheres to various building materials such as metals, glass, concrete, wood and other synthetic materials such as PVC, polystyrene and polyester. The use of this product is very effective for all of the above reasons, but it also carries certain risks if the method of use is not known. One of the problems that can arise is that of polyurethane foam stains on different surfaces in the home but also on the hands.If you have been stained with this material and want to discover how to remove polyurethane foam from hands and other surfaces, in unCOMO we recommend that you continue reading this practical article.

If alcohol or acetone have not been enough to clean the polyurethane putty from the hands, opt for other solutions to finish achieving it or to use directly in cases where the stains are recent and very fresh. One of them is the washing of the hands, as you usually do but with more insistence on the stained areas.

Polyurethane foam for ceilings

It is very likely that you have heard the word ‘polyurethane’ on several occasions, but… what is it really and what is this material for? This is a question asked by many people who are not completely familiar with this field of construction.

If we continue talking in chemical terms, we will explain how polyurethane is formed. It is obtained by the reaction of a polyol (polyhydric alcohol with different hydroxyl groups) with a diisocyanate or a polymeric isocyanate (these are fundamental compounds of polyurethane). Their shape will depend on the variety of polymers and all will depend on the polyol or isocyanate.

Nylon is often used in conjunction with polyurethane to create elastic and easier-to-wear clothing, which is used mainly for sportswear and shoes, among other accessories.

It is a prerequisite in cars, as it is used for everything. Nowadays, vehicles with a lower weight are sought after, and for this purpose this material is used, thus also increasing fuel economy. Therefore, comfort and safety come hand in hand with this material we are talking about, in seats, bumpers, roofs, doors, bodywork, etc.

How to apply polyurethane foam on a ceiling

But what about ceilings?  Ceilings are the forgotten ones when it comes to insulation. These also present insulation problems that can be solved by applying polyurethane foam.

After the application of polyurethane foam, a decrease of more than 30% of the ceiling temperature is achieved, and energy savings of up to 40% through the regulation and reduction of heat energy leaks.

The ceilings, being a horizontal enclosure, must be insulated underneath with sprayed polyurethane. This solution is valid for both new construction and renovation.

Polyurethane foam

Expanded polyurethane foam is one of the main materials currently used in various fields, such as construction of houses, buildings, boats or ships, airplanes, among others.

Polyurethane is a substance that results from the combination of “isocyanate” and “polyol”, through a chemical reaction. This combination allows the material to be stretched, crushed or scratched and not lose its constitution, which makes polyurethane a very resistant, almost indestructible material. Polyurethane is available in liquid, foam or solid form.

Polyurethane foam is a very safe working material when the safety standards that are usually indicated on the packaging are met. It is very important that personal protective measures are taken while applying EDP.
