The objective of this position is to investigate the effect of flame retardant on the processability of sprayable HMPSA.

Position Overview:

Sprayable hot melt pressure sensitive adhesives (HMPSA) have been applied increasingly in bonding battery cells (prismatic and pouch type) in electric vehicle (EV) industry due to facile processing. It is crucial for EV battery adhesives to have flame retardancy which can be achieved through incorporation of flame retardant (FR) fillers. However, the addition of FR fillers affects the processability and properties of HMPSA. Understanding the effect of FR additives on the adhesives will be the key for the development of HMPSA for pouch or prismatic EV battery cells, earning HB Fuller a leading position in the fast-booming EV market.  

Primary Duties:

  • Gathering physical and chemical information of FR fillers, e.g., particle size and viscosity in molten state.
  • Evaluate the dispersity of solid FR fillers in the HMPSA by optical microscope or Hegman grind method. 
  • Design experiments that relate the FR content and composition with viscosity using capillary rheology.    

Minimum Requirements:

  • Basic Microsoft office, Origin, MATLAB, Minitab or statistical software. 
  • Working towards Bachelor’s degree in Chemical Engineering, Chemistry, Material Sciences (or equivalent experience).
  • Basic chemistry lab or polymer processing experience  

Physical Environment:

40 hours a week. 30% of time in the office, 70% of time in the lab.
