PLENSET

Feature

Drop impact resistance type
(Flexible, Elastic adhesive and stretchable performance)

Features

  • Reduces stress under curing because it converts into a rubber-like flexible material when undergoes curing, and has flexibility enabling it to absorb mechanical impact, vibration and the like
  • Effective in bonding different types of materials between which there is a big difference in coefficient of thermal expansion, and has high bonding strength against peeling
  • AE-403H, AE-421D and AE-421H as flexible “PLENSET” meet Br and Cl requirements for halogen free as defined in IEC 61249-2-21.
    (IEC 61249-2-1 definition:900 ppm maximum chlorine, 900 ppm maximum bromine, 1500 ppm maximum total halogens)

Uses

  • Bonding parts which will be subjected to impact load, vibration load or the like
  • Bonding different kinds of materials
  • Bonding parts that are required to have flexibility
  • Bonding thin-film components in places where curling is undesirable
