Uses & suitable surfaces

Typical Uses: Door and window sealing, weatherstripping, gasketing, gap filling, access panels, enclosures, machinery cushioning, anti-rattle protection, sound dampening and vibration reduction.

Suitable Surfaces: Metal, painted metal, plastic, UPVC, glass, wood, painted surfaces, panels and frames. For best adhesion, surfaces should be clean, dry and smooth. Always test first where suitability is uncertain.

Not suitable for: Oils, fuels, solvents or aggressive chemicals; electrical insulation, conductive applications or live circuits; submerged conditions; structural fixing or safety-critical applications.

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 — take particular care on dusty, damp, rough, porous, delicate, freshly painted, coated or high-value surfaces.

Frequently asked questions

What is EPDM sponge tape used for?

EPDM sponge tape is used for sealing, gasketing, cushioning, weatherstripping, gap filling, anti-rattle protection and vibration dampening.

Is EPDM sponge tape suitable for outdoor use?

EPDM offers excellent resistance to ozone, UV and general weathering, making it suitable for many outdoor and semi-outdoor applications. Always confirm suitability for the specific application.

Is EPDM sponge 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 or waterproof membrane joint.

What is the difference between EPDM and neoprene sponge tape?

EPDM is generally better suited to UV, ozone and weather exposure. Neoprene is often preferred where resistance to oils and fuels is required.

Can EPDM sponge tape be cut to size?

Yes. It can easily be cut to the required length using scissors or a sharp knife.

Product Description

Flashback® 1mm EPDM Sponge Rubber Tape is the thinnest grade in our EPDM range — a high-density, self-adhesive closed-cell foam strip for thin sealing, precision gasketing, light cushioning and anti-rattle protection.

At just 1mm thick it adds almost no bulk, making it useful for narrow gaps, fine gasketing, light contact protection and tight-fitting parts where a thicker foam would hold components apart. Manufactured from closed-cell EPDM sponge rubber at approximately 120kg/m³, it offers excellent resistance to ozone, UV and general weathering.

Supplied on 10m rolls in widths from 10mm to 100mm, with a single-sided pressure-sensitive adhesive backing for quick application to clean, dry, smooth surfaces.

Key Features

  • 1mm thickness — the slimmest profile in the EPDM range
  • High-density closed-cell EPDM sponge rubber, approx. 120kg/m³
  • Self-adhesive single-sided backing
  • Excellent ozone, UV and weathering resistance
  • Helps seal against air, dust and moisture
  • Flexible and easy to cut to length
  • 10m rolls, widths from 10mm to 110mm

Is 1mm the Right Thickness?

Choose 1mm when you need a seal or cushion that adds minimal thickness — fine gasketing, narrow gaps, light contact protection, anti-rattle strips, cabinet and enclosure seals, or padding delicate equipment.

Choose a thicker grade when you are filling a visible gap or sealing draughts around doors, windows, sheds or garages. At 1mm there is very little material to compress, so a thicker EPDM tape will seal an uneven or wider gap far more effectively.

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