Flexible Foam Tape

Functional 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.

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

特性 2.せん断保持特性
Adherend Glass/SUS
Size of tape to be applied 25mm×25mm

3Evaluation results

特性 2.せん断保持特性
  • High shear holding properties are exhibited.

3Reworkability

1 Simulated 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.

3 Evaluation results

特性 3.リワーク性
  • Sekisui’s tapes have less foreign substance than other companies’.
    As for polyolefin products, there is no contamination by foreign substances.
