Understanding Different Foam Tape Core Materials

| 1

Foam bonding tapes feature a variety of core materials and it can be a bit bewildering as to why.

The most common types of foam core chemistries are:

  •    Acrylic
  •    Polyurethane
  •    Polyethylene

The foam core performs several vital functions within the bond area:

  •    It distributes loads over a large area enhancing energy absorption
  •    Improves stress relaxation
  •    Compensates for substrate mismatch and lack of planarity
  •    Enhances conformability

Each core chemistry offers a unique set of properties making it suitable for certain applications. The best way to visualize this is by observing the stress strain curves of each type:
