Hot melt adhesive pellets and stick are widely used to position, bond and seal electrical components, and in the process of low pressure molding for the protection of electric wires and cables.

The following hot melt adhesives we recommend offer good viscosity and their viscosity will remain unchanged whether in high or low temperature conditions. This significantly reduces the influence of temperature changes resulting from electrical current.

Application
  • Glue stick and adhesive pellets are used for the bonding and positioning of electric components
  • Glue stick and adhesive pellets are used for bonding electric wires
  • Adhesive pellets are used for positioning circuit boards
  • Moisture curing PUR hot melt adhesive is used for sealing mobile phone frames
  • Hot melt adhesive pellets are used to make heat-shrinkable tube liners
  • Hot melt glue pellets are used for low pressure molding
Examples
