Best Insulation & Sealing Foam Materia


NBR foam sheet material, also called Vinyl Nitrile foam or PVC NBR foam, is one of most useful and excellent foam materials. They can be fabricated to be Nitrile foam tapes, strips, gaskets, pads, sheets and so on. NBR foam are mostly used for seals, gaskets, heat insulation, soundproof and vibration dampening applications. They are foamed polymer blend of PVC and Nitrile rubber materials. It is foamed Nitrile foam not like the solid and rigid Nitrile rubber.

Here is how you can easily distinguish NBR foam from other foam materials

When you get a piece of NBR foam sheet from foam suppliers, you can quite easily distinguish it from other foam materials like EVA foam, Polyethylene foam and Neoprene sponge by following the below 3 main methods:

1. Finishing and Appearance. The real PVC Nitrile foam have a very smooth, even and soft outer skin on one side or on both sides (for foam thickness above 8 mm). Its surface offers a flexible and resilient touch. For the side view, you can clearly find out plenty of clear foamed cells inside the foam sheet. They comes in black color usually, but other colors can also be flexibly customized such as colorful NBR yoga mats.



2.Foam Sheet Size. The Vinyl Nitrile foam sheets are manufactured originally and finished in rolls with width of 1 meter and length up to 10 meters. Also its thickness can range from 2 mm to 40 mm. As mentioned before, NBR foam with thickness below 8 mm can only have soft skin on one side. Additionally PVC Nitrile foam can be fabricated in both closed cell foam structure and open cell foam structure. But for most applications, closed cell PVC Nitrile foam is the popular and typical choice.


3.The Finished Products. For foam fabrication, PVC Nitrile foam is easy to work with most of fabrication machinery such steel die-cutting, PSA foam lamination, vertical sawing and custom pad printing. Through all these fabrication processes, we have the capabilities to turn PVC NBR foam into Nitrile foam tape, foam seals, foam gaskets, foam sealing strips, printed foam mats, foam seat cushions and so on.

Nitrile Foam Usage and Products:

NBR Foam Gaskets, Seals and Strips


PVC NBR foam sheet has outstanding sealing and insulation abilities. They can also easily be fabricated to NBR foam gaskets, foam seals and foam weathering strips which widely used for construction and building, automotive and other industrial applications.

Nitrile Foam Tape

As Vinyl Nitrile foam has so many good physical properties, they are quite suitable to be manufactured as foam tape with or without adhesive backing. By utilizing our high efficient automated slitter, we have the capability to process PVC/ Nitrile foam tape in various custom sizes.





Egg Crate Convoluted Nitrile Foam Sheet

Besides, NBR foam sheet can also be convoluted into egg crate convoluted Nitrile foam just like polyurethane foam. The convoluted Nitrile foam can be powerful sound barriers and present superior acoustic insulation and fire retardance performance for lots of application including acoustic conference rooms, theaters and required testing rooms etc..


We Dengyue is a specialized foam manufacturer and fabricator. Our foam materials include EVA foam, Cross linked Polyethylene foam, PVC/ NBR foam, Neoprene foam rubber etc.. PVC NBR foam is one of the main materials we are working with. They can be highly customized by us to be NBR foam sheets, strips, tapes, gaskets and pads. Also  work closely with customers for best custom solutions on various applications when using PVC Nitrile foam.
