    • Coating for many kinds of hard cheese, like Edam cheese
    • Sealant for jars, cans, and bottles
    • Chewing gum additive
  • Investment casting
  • Anti-caking agent, moisture repellent, and dustbinding coatings for fertilizers

  • Forensics aid: the nitrate test uses paraffin wax to detect nitrates and nitrites on the hand of a shooting suspect

  • Mechanical thermostats and actuators, as an expansion medium for activating such devices[10]
  • "Potting" guitar pickups, which reduce microphonic feedback caused from the subtle movements of the pole pieces
