EPDM Foam Tape
EPDM Foam Tape
EPDM foam tape is a closed-cell foam tape with strong adhesive backing, used for sealing, gasketing and vibration dampening. Its compressible structure lets it fill gaps and conform to uneven surfaces while resisting moisture and weathering.
- Closed-cell EPDM foam core — resists water absorption
- Compressible, conforms to uneven or textured surfaces
- Available in multiple thicknesses for different gasketing needs
- Suitable for indoor and outdoor sealing applications
Description
Product Overview
EPDM foam tape is built on a closed-cell EPDM (ethylene propylene diene monomer) rubber foam core, coated with a pressure-sensitive adhesive on one or both sides. The closed-cell structure resists water absorption, making it a common choice for outdoor gasketing and sealing where compressibility and weather resistance both matter. It compresses under pressure to fill irregular gaps, then recovers to maintain continuous contact — a property acrylic or rubber-resin tapes without a foam core cannot match.
Adhesive Specialities supplies EPDM foam tape in multiple thicknesses to suit different gap sizes and compression requirements.

EPDM Foam Tape vs PE Foam Tape vs Acrylic Foam Tape
| Type | Best for | Key trait |
|---|---|---|
| EPDM Foam Tape | Outdoor gasketing, weatherstripping | Closed-cell, water-resistant, good compression recovery |
| PE (Polyethylene) Foam Tape | Light cushioning, general padding | Lower cost, less compression recovery than EPDM |
| Acrylic Foam Tape | High-strength structural bonding | Solid acrylic core (not open/closed-cell foam in the traditional sense), very high bond strength |

Frequently Asked Questions
What is EPDM foam tape used for?
EPDM foam tape is used for sealing, gasketing and vibration dampening in HVAC, construction and appliance assembly. Its closed-cell foam core compresses to fill gaps while resisting moisture.
What is the difference between EPDM foam tape and PE foam tape?
EPDM foam tape uses a closed-cell rubber foam that resists water and holds its shape after compression, making it suited to outdoor gasketing. PE foam tape is typically used for lighter cushioning applications where water resistance is less critical.
Is foam tape waterproof?
Closed-cell EPDM foam tape resists water absorption because its cell structure does not allow water to pass through, unlike open-cell foams.
How thick should foam tape be for gasketing?
Thickness should match the gap being sealed and the compression the joint allows — thicker foam is used for larger or more irregular gaps.
Can EPDM foam tape be used outdoors?
Yes, EPDM foam tape is commonly used in outdoor applications such as weatherstripping and duct sealing because of its resistance to water and general weathering.
