Data Sheet

Proteus® LF PP (Lay Flat Polypropylene) is a proprietary Stable Machine Grade (SMG) formulated homopolymer sheet that exhibits superior dimensional stability and flatness after aggressive fabrication. Proteus® LF PP has excellent chemical and moisture resistance and is FDA and USDA compliant. Proteus® LF PP was designed to target applications where standard PP plate and sheet products cannot hold dimensional stability tolerances specified. Ultimately Proteus® LF PP will allow for faster cycle times, increase unmanned machine hours and eliminate costly secondary part finishing operations ultimately resulting in lower part cost. Advantages of Proteus® LF PP:

  • Saves time and money
  • Supreme dimensional stability and flatness
  • Enhancing the performance PP in cost conscious applications
  • Compliance equal to standard PP
  • Accelerated fabrication cycles
  • Eliminates post annealing and processing of parts


  • Orthotic and prosthetic devices
  • Plating and anodizing process equipment
  • Plenums and manifolds
  • Pump components
  • Secondary containment
  • Storage tanks
  • Valve bodies

Target industries:

  • Chemical processing & storage
  • Medical
  • Metal finishing
