Description
What is Polyurethane Foam Door Seals
Polyurethane foam sealants create an airtight and watertight teal, preventing water and air from penetrating an area. This type of sealant can be used to seal windows, doors, and corners.
The Advantages of Polyurethane Foam Door Seals
Simple To Use
First and foremost, polyurethane foam is extremely easy to use. You don't need to be an expert in insulation to apply polyurethane foam; in fact, any DIYer should be able to apply polyurethane foam at home with a little dedication. All you'll need to do to apply most types of spray polyurethane foam insulation is grab a foam gun and apply it carefully to the areas that need to be insulated.
Watertight And Airtight Seals
One advantage of polyurethane foam spray insulation is that it can form watertight and airtight seals, allowing for more durable structures and truly seamless insulation. Rigid polyurethane foam insulation creates strong, airtight barriers, which makes it the perfect choice for home insulation and for sealing windows and doors. Good home insulation like polyurethane spray foam has a high R-value, which means that it minimizes heat transfer (and your energy bills!) while maximizing your comfort.
Resistance To The Elements
Polyurethane foam is highly resistant to the elements, meaning that it can be used both outdoors and indoors and will hold up against moisture. Polyurethane is mold-resistant, too, so you don't need to worry about keeping it dry or growing mildew if you don't. Many other types of insulation materials are not mold and mildew-resistant, so this is one area where polyurethane foam stands out.
Versatility
Because of the wide range of benefits to using polyurethane foam, as well as its versatility, polyurethane foam sees a wide range of applications even outside of the insulation. For example, polyurethane foam is used to make kitchen sponges, and it is also a component in memory foam, which is used to make car seats, mattresses, pillows, and many more products.

Types of Polyurethane Foam Door Seals
One class of materials that find use in various sealing and gasket applications are sealing foams such as:
1.Polychloroprene (Neoprene) Rubber Foam
The monomer chloroprene (2-chlorobutadiene) can be obtained from acetylene and hydrochloric acid via monovinylacetylene, or through butadiene chlorination and dechlorination of 3,4-dichloro-1-butene. Many types and grades of polymers and copolymers of Polychloroprene are available and are known under the generic name Neoprene.
2.Nitrile Rubber (NBR) Foam
Nitrile Rubber is a copolymer of acrylonitrile and butadiene. A number of NBR type copolymers are manufactured, the two monomers are randomly distributed and the main difference between the copolymers is related to the amount of acrylonitrile (ACN) in the resultant polymer. The ratio between acrylonitrile and butadiene can vary from approximately 18% to 50%. If a higher heat and chemical resistance is required, this is achieved with a high ACN content. Where superior mechanical performance at low temperature is required, a lower ACN content type nitrile rubber needs to be selected as the glass transiton temperature (Tg) is affected by the % of ACN in the polymer.
3.EPDM Foam
Ethylene/Propylene rubbers are a random copolymer which generally contain about 35mol% of polypropylene, but rubber-like properties are shown by copolymers with a propylene content ranging from 30-60mol%. The ethylene/propylene copolymers being random copolymers do not contain any long chains of ethylene or propylene units so crystallisation cannot occur and they are completely amorphous. There is virtually no double bonds consequently vulcanisation by conventional techniques using sulphur is not possible and peroxides have to be used.
4.Silicone Rubber Foam
General purpose silicone elastomers are based on polydimethylsiloxanes, but special purpose products containing a small proportion of other groups other than methyl are also available. In order to obtain elastic properties it is necessary to crosslink the linear silicone macromolecules, this can be achieved in different ways. The most important methods are based on organic peroxides at high temperature and cross-linking with organometallic and organic silicone compounds at ambient temperature or temperatures slightly above ambient temperature.

Applications of Polyurethane Foam Door Seals
Automotive
Polyurethanes are used throughout cars. In addition to the foam that makes car seats comfortable, bumpers, interior "headline" ceiling sections, the car body, spoilers, doors and windows all use polyurethanes. Polyurethane also enables manufacturers to provide drivers and passengers significantly more automobile "mileage" by reducing weight and increasing fuel economy, comfort, corrosion resistance, insulation and sound absorption.
Flooring
Polyurethanes are also used to coat floors, from wood and parquet to cement. This protective finish is resistant to abrasion and solvents, and is easy to clean and maintain. With a polyurethane finish, a new wood, parquet or cement floor wears better and longer, while an old floor can be refinished to look new again.
Composite Wood
Polyurethanes play a major role in modern materials, such as composite wood. Polyurethane-based binders are used in composite wood products to permanently glue organic materials into oriented strand board, medium-density fiberboard, long-strand lumber, laminated-veneer lumber and even strawboard and particleboard.
Electronics
Often referred to as potting compounds, non-foam polyurethanes are frequently used in the electrical and electronics industries to encapsulate, seal and insulate fragile, pressure-sensitive, microelectronic components, underwater cables and printed circuit boards.
Rubber and polyurethane seals are commonly used for their material selection and physical properties. Depending on its environmental conditions and overall function, one material is usually a better option over the other. For example, leak tests are often an excellent application for polyurethane seals as helium is typically employed during testing. Unlike rubber, polyurethanes can exhibit superior abrasion resistance, tensile strength, and tolerances to greases, oils, oxygen, and ozone. In addition, polyurethanes like thermosets can offer product engineers an endless range of customizable formulations and manufacturing capabilities to achieve complex geometries and better performance for extended wear. Because rubber is biodegradable, it tends to rot and degrade over time with exposure to certain elements - leading to potentially inaccurate test results and frequent seal replacements. For this reason, polyurethanes are often preferred for applications that require very specific physical properties for improved performance.
If you find custom leak test seals are a key requirement for improved performance, this can easily be tailored by your thermoset polyurethane manufacturer. For material assistance, complete our design tool here, or click the button below to start your custom polyurethane seal today.
