High-impact Absorbent Foam

Acrylic Foam ISR-ACF/ISR-ACF-TH/ISR-ACF-SFU

Feature

  1. 1)This is an acrylic foam with excellent impact absorbance performance.
  2. 2)Due to its low density, it can be compressed with a low load.
  3. 3)The type with self-absorption on the surface can be temporarily fixed or reworked. A type without self-absorption on one side is also offered.

Acrylic Foam ISR-ACF-SFT/ISR-ACF-SFH

Feature

  1. 1)This is an acrylic foam with excellent impact absorbance performance.
  2. 2)Due to its low density, it can be compressed with a low load.
  3. 3)As the base material has stretching properties, in a standalone foam comparison, degradation in impact absorbing performance can be controlled and it features excellent durability against repeated impacts.
  4. 4)By setting an adhesive layer underneath the urethane film, lamination onto curved surfaces such as flexible displays is also possible as a foam tape with stretching properties.

Application

  1.  ・Impact absorbing and buffering materials and vibration suppression measures for mobile precision devices such as smartphones, car navigation systems, tablet devices and remote controls, liquid crystal displays (LCD), organic light emitting displays (OLED) and other electronic devices
  2.  ・Ripple (pooling) measures for LCDs
  3.  ・Impact absorbing and buffering materials for flexible displays, vibration suppression measures
