• Ability to be polished
    • describes whether and to what degree the material can be finished
    • values range between a matte and a high gloss finish
  • Bacterial - fungal resistance
    • the material's ability to inhibit the growth of bacteria and fungus
  • Barcol Hardness
    • a scale that defines hardness compared to similar materials (typically between 45 and 65)
    • A high reading above the typical range could indicate a brittle material. A low reading could indicate under cured material
  • Color stability
    • The lower the color change the better it is
  • FDA approved
    • The FDA tests individual final products which demonstrates the non-adulteration of food
  • FDA compliant
    • This is a less rigorous standard than FDA Approved
  • Flexural Modulus
    • Describes the stiffness, a measure of the resistance to deformation under load
    • A low Flex Modulus indicates a material that requires more support
    • A high number indicates a material that may not be forgiving enough to be flat on an imperfect surface
  • Flexural Strength
    • The amount of force required to bend and break the material when a specific thickness, test piece is bent.
  • High temperature resistance
    • The ability of the material to retain its integrity when exposed to high temperature (365 °F)
  • Home chemical resistance
    • How the material maintains its integrity when exposed to typical household chemicals
  • Impact resistance
    • The resistance of the material to being chipped or broken by an impact
  • Laboratory chemical resistance
    • How the material maintains its integrity when exposed to laboratory chemicals
  • Scratch resistance
    • The amount of force necessary to scratch the material
  • Stain resistance
    • How ten household materials (covered and uncovered) can initially leave a mark on the surface and how much effort is required to remove the mark
  • Surface conductivity
    • A test of the electrical resistance or conductivity of the material
  • Thermal Expansion
    • How much the material expands upon warming and contracts upon cooling
  • UV weathering stability
    • How the color and the surface appearance change as the material is exposed to ultraviolet light
  • Water resistance
    • A test that determines the ability of the material to withstand repeated exposure to water
  • Wear resistance
    • The resistance to being worn away during continuous exposure to cleaning or scrubbing brushes with respect to maintaining the initial gloss
