What Material Can Be Used In Vacuum Forming?

Vacuum forming is a process that involves heating a sheet of plastic until it becomes pliable, and then using a vacuum to form it over a mold. The most commonly used materials for vacuum forming include:

  • Acrylic (also known as polymethyl methacrylate or PMMA)
  • Acrylonitrile butadiene styrene (ABS)
  • Acrylonitrile-styrene-acrylate(ASA)
  • Polyethylene (PE)
  • Polypropylene (PP)
  • Polystyrene (PS)
  • Polyvinyl chloride (PVC)
  • High-impact polystyrene (HIPS)
  • Thermoplastic elastomers (TPEs)
  • Fluoropolymers (such as PTFE and FEP)
  • Polycarbonate (PC)
  • Polyethylene terephthalate (PET)

It is worth noting that vacuum forming is generally used for thermoforming thermoplastic materials, rather than thermosetting materials like epoxies or polyurethanes. These materials do not become pliable when heated and cannot be formed using the vacuum forming process.
