  NOTE.—The values for the properties in this table are based upon
  maximum and minimum figures submitted to Modern Plastics by a
  number of manufacturers of each type of material. Differences in
  test procedures and sizes of test specimens may lead to erroneous
  conclusions in some cases if direct comparisons are attempted.
  Special grades of materials are often available which excel in
  one particular property.
