The Polaroid film shown has poor red sensitivity and almost resembles a Tungsten film in speed distribution. The dmax is very low and the latitude only covers about 1/2 of that seen in most modern films.

About half way down the page they show the technical specifications of a typical Kodak B&W film and you see that this film has about 2x the latitude and a lot more red sensitivity. This is typical of Kodak films and is quite different than the T-55 data in the Polaroid link.
