NBR (Nitrile Butadiene Rubber) is one of the most useful and efficient types of foam. Its resistance against chemicals and heat as well as its flexibility is exceptional. NBR is being used in very sensitive situations where other foam materials fail to endure or resist.
Weak Against Highly Polar Solvants like Acetone, Not suitable against MEK, Ozone and Hydrocarbon
High Tensile Strength, Resistant to Heat, Water, Oil and Acids good, Strong against Abrasion, Gas Permeability and good Compression set
Automotive and Aeronautical industries, Nuclear Industry gloves, Sealing, Footwear and Floor Mats, Isolated Walls
In this article, we want to introduce the NBR Foam & every aspect of this product.
NBR Rubber can be customized by us to gaskets, tapes, pipes, egg crate & cushions products.
To make a better decision, we tried to explain every aspect of NBR rubber. We hope this article helps you to make a better decision for what you want.
After reading you can share your experiences with us.
NBR (Nitrile Butadiene Rubber) is a synthetic co-polymer with various butadiene monomers.
NBR Foam also has different commercial names such as Perbunan, Nipol & Europrene.
The synthetic rubber (like NBR) is usually resistant to oil & chemicals.
If we have more nitrile within the polymer, the behavior changes. For example, the resistance against oils increases but the flexibility of materials decreases.
NBR Foam sheet , for example, has a key element, the “nitrile”. The nitrile plays an important role because the chemical & physical properties rely on the composition of nitrile.
At first, we have the raw material. The raw material is yellow. After the manufacturing process, the material can be orange or red-tinted. At the end of the procedure, we have hot NBR Foam!
The hot NBR rubber has radical generating activators & added catalyst to polymerization vessels.
There is no major difference between the production of hot NBR & cold NBR. In fact, the cold NBR or hot NBR Foam is distinguishable with the number of branches.
In the procedure of monomer recovery, the unwanted solids were removed by latex which is sent through numbers of filters where it stabilized with “antioxidant”.
You can understand the difference between NBR rubber & any other kind of foam-like EVA Foam immediately.
In fact, when you get a piece of NBR foam from suppliers, you will find out the difference between the NBR foam & any other kind of foams like EVA foam , etc.
After the production of PVC Nitrile, we have a very smooth & soft outer skin on both sides.
This surface has a resilient touch and good flexibility. You can even use this resilient surface for some applications like yoga.
The cells of the foam are clear on the surface sheets.
The final product of NBR is a black piece of foam. You can also work with cutting & fabrication machinery like foam lamination (PSA) & Die-Cutting system.
In the whole procedure of NBR production, you will be able to transform the NBR to different kinds of foam products like gaskets, mats, tapes & seals.
The “Hong Kong Foam” company can produce customized products according to customer requirements.
The NBR has opened cell structure & closed cell structure that the closed cell is more popular & more efficient for producing the different kind of foams.
NBR is a wonderful product that we can create thousands of applications of this foam. You can also see the benefits of NBR Foam on below:
We have also disposable non-latex or latex-free gloves for nuclear uses & automotive transmission belts manufactured from NBR Foam.
The one the most important feature of this product is the NBR Foam has great resistance to mildew, ozone & fungi.
Gaskets & seals are widely used in different industries like construction & building, automotive & any other kind of industrial application.
NBR has also flexible against wide range temperatures.
According to the physical properties, NBR rubber is appropriate to be made as tape without any kind of adhesives.
NBR is one of the most popular foam for energy saving & thermal insulation applications. It is also ideal for HVAC system. You can also laminate the aluminum foil with NBR for better heat & sound insulation.
Just like PU (Polyurethane) Foam, NBR Foam can also be laminated into convoluted egg crate nitrile foam.
The egg crate NBR is perfect noise insulation & sound barrier for places like cinemas, theaters & conference rooms.
NBR can also be fabricated in sports accessories like yoga mats.
NBR rubber is also soft & resilient that means it is suitable for a seat cushion. You can easily print the various & custom designs on the surface of NBR for better marketing & commercial purposes.
Hong Kong Foam is a foam fabricator & manufacturer that NBR is one of the main materials we are working with.
Our products are reliable with the latest standards.
