PLASTISOL

• Plasisol is a vinyl compound that is liquid at
  room temperature and will keep for years.
• When heated it fuses into ordinary vinyl never to
  liquefy again.
• Plastisol is non thermal plastic which means once
  it has hardened it can not be melted.
• It is available in an unlimited amount of colors.
