3M Polyethylene Foam Tapes: 4462, 4466, 4492, and 4496 (Including 4496B Variant)

3M polyethylene foam tapes are a trusted solution for sections where foam is needed along with sticky backing. Built on a closed-cell polyethylene foam core, these double-sided tapes provide conformability, shock absorption, and durable adhesion across metal, plastic, and painted surfaces.

What Is a Double-Coated Tape?

A double-coated tape is a pressure-sensitive adhesive tape that has adhesive on both sides of a carrier — in this case, a polyethylene foam. Unlike single-sided tapes, double-coated tapes are designed to bond two surfaces together or alternatively allowing easy application, creating a hidden, clean attachment without visible fasteners. The foam core allows it to:

• Fill gaps and irregularities

• Absorb vibration or movement

• Maintain a uniform bond line between surfaces

This makes double-coated foam tapes ideal for mounting fixtures, trims, signage, and hardware where aesthetics and reliability are equally important.

Key Advantages of 3M PE Foam Tapes

• Closed-cell polyethylene foam for cushioning

• Adhesive on both sides for hidden bonding

• Shock and vibration dampening

• Clean, peel-and-stick installation

• Suited for a wide range of substrates

Selection Reference

Why Foam Tapes Excel in Assembly

Unlike rigid fasteners, foam tapes create a bond line that absorbs movement, compensates for surface irregularities, and protects materials from stress. The result is a clean, professional finish without drilling, clamping, or curing time.

Waterjet Cutting/Lamination/Die-Cutting

At NEDC, we die-cut, laser-cut, waterjet cut, and otherwise convert 3M tapes into finished shapes. If needed, we also laminate these tapes from 3M Company onto different substrates and then cut them like a little sandwich.
