Easy-to-Dismantle/Easy-to-Remove Foam Tape
A reusable flexible foam tape that combines strong holding power with reworkability
A flexible foam tape composed of polyolefin or polyurethane substrates combined with a high-adhesionadhesive. Ideal for securing panels and enclosures,it offers excellent cushioning and conformability. It also features reworkability, allowing for the disassembly and reuse of parts. Suitable for a wide range of applications, including TVs, monitors, and in-vehicle parts, it ensures reliable bonding even between dissimilar materials.
- Electronics
Structure & Features
- Holding performance on tilted surfaces that can withstand static heavy loads
- Easy-to-Remove properties that enables manual removal of the tape from bonded objects
- Flexible foam absorbs repulsion to conform to curved surfaces without lifting or peeling
Features
1Strong holding performance on tilted surfaces
Simulated situation for evaluation
This evaluation is based on the assumption that the flexible foam tape was used to install a TV set obliquely.
Evaluation method
- Stick glass or SUS objects together with a clamp over the tape.
- Hang a 1 kg weight from it and measure how long it takes to fall.
| Measurement temperature | 60°C 90%RH |
|---|---|
| Tape size | 25mm × 25mm |
| Pressure application conditions | 5kg*10sec |
| Curing conditions | 23°C 50%RH*24hr |
| Tilt angle | 45° |
| Test duration | Up to 500h |
Results
SEKISUI’s super strong base materials keep adherends from falling even in tilt retention tests.
2Strong hydrolysis resistance performance
CheckShear tensile test in hot and humid conditions
Evaluation method
- SUS objects are stuck together with a 25 mm piece of tape and left for 24 hours to cure, and then the shear strength is measured.
- They are left in 85°C, 85% RH conditions and the shear strength is measured at intervals until 1,250 hours have passed.
- With the shear strength at 0 hours as the baseline (100%), the relative strength (%) at each measurement time point is calculated.
| Adherend | SUS/SUS |
|---|---|
| Tape size | 25mm × 12.5mm |
| Pressure application conditions | 5kg × 10sec |
| Curing conditions | 2After 24h at 23°C, 50%RH, store at 85°C, 85%RH |
| Test temperature | Remove from the oven to cool and then measure at 23°C, 50%RH |
| Test speed | 12.7ｍｍ/min |
Results
SEKISUI’s PE products retain base material strength even with long-term use as they do not deteriorate from hydrolysis.
3Very easy to dismantle
Evaluation method
Two PC panels are stuck together with a 5 mm wide piece of tape, and the tape is removed after the form layer splits and disintegrates.

4Curved surface tracking performance
Simulated situation for evaluation
Tested assuming use on a curved screen with the housing as the PC adherend.
Evaluation method
- Two pieces of PC board are taped together, clamped, and left for 24 hours.
- The PC boards are bent and checked for lifting and peeling of the tape.
| Test configuration | Evaluation based on the difference in OLS09D configuration glue |
|---|---|
| Adherend 1 | PC board 2mm × 25mm × 150mm |
| Adherend 2 | PC board 1mm × 25mm × 200mm |
| Tape size | 3mm × 150mm |
| Pressure application conditions | 2 kg roller X 1 time in both directions (10 mm/sec) |
| Curing conditions | 23℃ 50%RH*24hr |
| Test temperature | 60℃ 90%RH |
*With a chord length of 165 mm and arc length of 200 mm, R (radius) = 95 mm (actual R is 95 mmv due to PC rigidity<)
Results
| Lifting distance | X adhesive |
|---|---|
| Lifting after 1h | 0mm |
| Lifting after 7 days | 0mm |
X adhesive has excellent repulsion resistance against PC adherends.
