Definitions

  • a further object of the present invention is to provide a starch based biodegradable material with increased fluidity in injection molding conditions and a higher crystallization temperature, thereby allowing the industrial output to be improved.
  • the bone is molded in a 22 second cycle.
  • the bone thus obtained was subjected to a gastric and intestinal digestibility test and to a soiling test.
  • Samples of fragments of bone according to the invention of the weight of 10-20 grams were made to react in pH conditions simulating first the gastric and then the intestinal environment, consecutively.
  • Example 1 The extruder of Example 1 was supplied with:
