(Easy Rework)
Flexible Foam Tape
Our Flexible Foam Tape is used for fixing TV/monitor panels and modules. The tape consists of polyolefin (PE) / polyurethane (PU) foam carrier with excellent stress relaxation (cushioning) and strong adhesive materials.It suppresses mura on screen even in large panels and has reworkability that enables device reuse. It also has excellent shear holding properties, holding properties on tilted surfaces, and repulsion resistance, making it suitable for curved surfaces and narrow bezels.
Features
- High holding properties.
- Great reworkability. Less contamination are found in Sekisui’s tapes than other companies’ during rework. When our tapes are used in polyolefin products, no contamination are detected.
Applications
Application example of the Flexible Foam Tape
Feature
1. Holding properties on tilted surfaces
1Simulated situation for evaluation
This evaluation is based on the assumption that the flexible foam tape was used to install a TV set obliquely in a bar or a restaurant.
2Evaluation method
| Tape c | 25mm×25mm |
| Adherend① | PET surface on the glass |
| Adherend② | AL |
| Adhesive load | 5kg×10sec |
| Curing conditions | 24h*23℃50%RH |
| Gradient | 45° |
| Static load | 1kg |
| Measurement temperature | 60℃90%RH |
3Evaluation results
- Great holding properties are exhibited.
2. Shear Holding Properties
1Simulated situation for evaluation
Static shear strength applied to the flexible foam tape was measured on the assumption that the tape was stuck to the back of a LCD display.
2Evaluation method
| Adherend | Glass/SUS |
| Size of tape to be applied | 25mm×25mm |
| Pressure application conditions | 1 pass back and forth with a 2-kg roller |
| Curing conditions | 23℃×24hr |
| Test conditions | 60℃90%RH |
3Evaluation results
- High shear holding properties are exhibited.
3. Reworkability
1Simulated situation for evaluation
An evaluation was conducted to determine how many foreign substances there were when the flexible tape was torn off during disassembly of devices or other things.
2Evaluation method
3Evaluation results
- Sekisui’s tapes have less foreign substance than other companies’. As for polyolefin products, there is no contamination by foreign substances.
