Product Description

Flashback® 15mm EPDM Sponge Rubber Tape is our thickest self-adhesive, closed-cell EPDM foam tape, for sealing large gaps, heavy cushioning, panel protection and vibration reduction.

At 15mm thick it gives the most depth and compression in our EPDM range, making it useful for large gap filling, larger seals, garage, shed and workshop sealing, protective padding for frames, panels and equipment, softening contact and light impacts between hard surfaces, and draught reduction where the gap is too big for thinner tape. The closed-cell structure helps seal against water, air and dust, and EPDM's ozone and weathering resistance is rated excellent on our data sheet.

Supplied on 5m rolls in widths from 10mm to 100mm, with wider widths up to 930mm available to order. The single-sided acrylic pressure-sensitive adhesive allows quick application to clean, dry, smooth surfaces, and the finished tape is rated for use from -20°C to +80°C.

Key Features

  • 15mm thickness, the thickest in our EPDM range
  • Closed-cell EPDM sponge rubber, classified to ASTM D1056 2A1 B3
  • Density 70 to 100 kg/m³
  • Ozone and weathering resistance rated excellent
  • Helps seal against water, air and dust
  • Passes FMVSS 302 flammability test

Is 15mm the Right Thickness?

Choose 15mm when the gap is large or very uneven, or you need the heaviest cushioning: large gap filling, garage, shed and workshop sealing, deep protective padding and vibration reduction between surfaces. Because it is so deep, check it will compress enough for the door, lid or panel to close properly.

Choose a thinner grade when the gap is smaller, where 10mm or 8mm will be easier to fit, or compare all thicknesses.

Important: This is an EPDM sponge sealing and cushioning tape. It is not a roofing seam tape, flashing tape or waterproof membrane tape.

How to apply
  1. Ensure the surface is clean, dry and free from dust, grease and loose material.
  2. Measure and cut the tape to the required length using scissors or a sharp knife.
  3. Remove the release liner and carefully position the tape before pressing down.
  4. Apply firm, even pressure along the full length.
  5. Allow the adhesive time to bond before placing the tape under compression or stress.

Always test first to confirm suitability for your surface and application. Adhesion varies with surface condition, temperature and environment, so take particular care on dusty, damp, rough, porous, delicate, freshly painted, coated or high-value surfaces.

All figures are typical values, not a guaranteed specification. The working range of the finished tape is -20°C to +80°C, set by the sponge rubber. This tape is not certified for electrical, structural, chemically exposed, submerged, automotive safety-critical or load-bearing applications. Suitability depends on surface, compression, temperature, environment and installation. Always test before full use. Flashback Tape accepts no liability for misuse or improper installation.

Frequently asked questions

Is 15mm the right thickness for my gap?

15mm is our thickest EPDM tape, for large gaps and heavy cushioning. Because it is so deep, check it will compress enough for the door, lid or panel to close properly. For smaller gaps, 10mm or 8mm will be easier to fit.

What is EPDM foam tape used for?

Sealing, gasketing, cushioning, weatherstripping, gap filling, anti-rattle protection and vibration dampening.

Is EPDM foam tape suitable for outdoor use?

EPDM's ozone and weathering resistance is rated excellent on our data sheet, and the tape is rated for use from -20°C to +80°C, making it suitable for many outdoor and sheltered applications. Always confirm suitability for your specific application.

Is EPDM foam tape waterproof?

Closed-cell EPDM helps resist water ingress, but the finished seal depends on compression, surface contact and installation. It should not be used as a roofing seam, flashing tape, waterproof membrane joint, or in submerged conditions.

Is EPDM the same as neoprene?

No. Both are synthetic rubbers used for sponge sealing tapes, but they suit different conditions. EPDM is generally the better choice for outdoor and weather-exposed sealing, while neoprene is often preferred where oils or fuels are present. EPDM is not suitable for contact with oils, fuels or solvents. Our EPDM vs neoprene vs foam tape guide compares them in detail.

Can EPDM foam tape be cut to size?

Yes. It cuts easily to length with scissors or a sharp knife.
