Automotive Industry (hot melt adhesive for automotive wire and filter)

Hot melt adhesive stick and adhesive pellets are used in the production of automotive wires and filters. Our self-developed formula improves the performance of hot melt adhesives by increasing their heat, oil, and weather resistance while simultaneously ensuring their viscosity, in order to meet the high demands of the automotive industry.

Applications
  • Bonding automotive wires
  • Bonding automotive filters
  • Bonding fabric to the roof of cars
  • Center console bonding
  • Automotive rear deck cover bonding
