Get to Know Properties, Advantages and Application of EVA Foam Sealing Tapes
What is EVA foam sealing tape?
EVA foam is essentially an acronym for closed cell ethylene-vinyl acetate copolymer foam. In production EVA foam is useful as an effective substitute for a variety of materials. Among other things, EVA foam is used as substitute for natural rubber, Polyurethane, PVC foams, Neoprene and vinyl Nitrile foam. It can also substitute wood composites, fiber, glass, felts and mineral wool. EVA foam sealing tape is made with EVA foam by foam slitting fabrication process.
How is EVA foam tape made?
It has a uniform cell structure which allows it to be processed just like other thermoplastics. Once made, it retains its resistance and flexibility and is capable of recovering quickly from compressions. EVA foam is originally formed in a mold which is later converted to a sheet of closed cell foam. The EVA foam is then cut into various sheets, and then just fabricated into various width and length of foam roll with or without adhesive back as foam sealing tapes by foam slitter machinery.
The properties of EVA foam sealing tape
Ideally it has been proved that using EVA foam tape characteristically provides a good gloss and clarity. It also has the property to remain strong even in extremely low temperatures. Besides, it exhibits a strong resistance to ultra violet radiation and stress cracking that might affect equipment. In addition to these, EVA foam sealing tape conveniently possesses waterproof and heat insulation properties.
The advantages of EVA foam Sealing tape
There are a lot of advantages and benefits when using EVA foam tapes as a substitute in production. These benefits all come in handy to ensure that products are well maintained against any sheer forces of the environment. For instance, EVA foam tape is very effective at absorbing vibrations and forces of impact. As a result, it reduces the possibility of unprecedented breakages when equipment fall, or are knocked over. It is also resistant to weather, chemicals, fuel spill, fuel splash, and oil. This significantly reduces corrosion and prevents damage by substances that are harmful yet are quite common and useful, such as chemical and fuel.
EVA foam sealing tape also provides thermal insulation and some significant resistance to acoustical properties. Moreover, it is resilient and exhibit marked buoyancy. It also has low water absorption properties.
The application of EVA foam tape
EVA foam tape is majorly used as an industrial tape for a variety of purposes. It proves to be helpful in aerospace, automotive, ship building, electronics, packaging, making decorations, and in foam equipment. In the electrical industry, it is used competitively as a substitute for rubber and vinyl products. When used to make plastics, it characteristically gives plastic wrap its clingy property. EVA foam sealing tape is developed into adhesives from EVA emulsions and is used in packaging, bookbinding, bonding coated papers, metal surfaces and plastic films.
Everything You Need to Know about Polyethylene Foam Tape

- PE foam sealing tape comes in double-sided variants. These double-sided variants are used for indoor and outdoor bonding and mounting, as well as window glazing applications (to seal windows from wind and moisture).
- Polyethylene foam sealing tape can be an inexpensive solution for a variety of household and commercial tasks.
Thanks to the durability of the Polyethylene foam in cross-linked structure and powerful hot melt adhesive, it is a very versatile and relatively inexpensive solution for a variety of mounting and joining needs. Typically it comes in either black or white finishes, depending on the aesthetic requirements of the job at hand. It can also be bought with various grades of adhesives, so the buyer can plan accordingly depending on whether the tape needs to hold for an extended period of time or needs to be easily removed. Overall, PE foam tape is a great catch-all solution for a wide variety of tasks, and is relatively affordable compared to more specialized products.
