When choosing foam tape for sealing, cushioning, mounting, or gasketing applications, PE Foam Tape and EVA Foam Tape are two of the most common options.
PE Foam Tape is softer, more compressible, and cost-effective, making it ideal for gap filling and light-duty sealing applications.
EVA Foam Tape is denser, more durable, and offers better recovery performance, making it the preferred choice for die-cut gaskets, industrial sealing, and applications requiring long-term durability.

What Is PE Foam Tape?
PE Foam Tape is a pressure-sensitive adhesive tape made from closed-cell polyethylene foam.
It is widely used for:
- Sealing
- Cushioning
- Vibration damping
- Gap filling
- Light-duty mounting
Its soft structure allows it to conform easily to uneven surfaces, making it an economical solution for many industrial applications.

Compression Recovery
PE Foam Tape
Good compressibility but may develop compression set after long-term loading.
EVA Foam Tape
Excellent rebound performance and maintains its shape longer after repeated compression cycles.
Durability
PE Foam Tape
Suitable for general-purpose applications with moderate wear requirements.
EVA Foam Tape
Better suited for demanding industrial applications requiring extended service life.
Abrasion Resistance
PE Foam Tape
Moderate resistance to wear and surface friction.
EVA Foam Tape

Frequently Asked Questions
Which Is Better for Gaskets?
EVA Foam Tape is generally better for gasketing applications because it offers stronger rebound performance and resists permanent compression.
Is PE Foam Tape More Waterproof Than EVA Foam Tape?
Both PE and EVA foam tapes typically use closed-cell foam structures and provide excellent water resistance.
Actual waterproof performance depends more on:
- Foam density
- Surface skin quality
- Adhesive system
Which Tape Supports Heavier Loads?
Mounting performance is primarily determined by:
- Adhesive type
- Bonding area
- Surface energy
However, EVA Foam Tape’s denser structure generally provides better support for heavier applications.
Can Both Materials Be Die-Cut?
Yes.
Both PE and EVA foam tapes can be converted into:
- Gaskets
- Washers
- Pads
- Custom die-cut components
EVA foam is often preferred when tighter tolerances and cleaner edges are required.
Conclusion
Both PE Foam Tape and EVA Foam Tape have unique advantages.
Choose PE Foam Tape When:
- Budget is important
- High compressibility is required
- Cushioning and sealing are priorities
Choose EVA Foam Tape When:
- Durability is critical
