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:
