I am looking for a bio-degradeable material that has shore A70 hardness. i want to use this material in place of shore A-70 TPU. It must be injection grade..
Talk to a custom compounder about providing you with a SBS compound containing starch. Look in the Modern Plastic Encyclopedia or Plastic technology handbook for sources. This will provide two mechanisms for the degradation to take place. Cost will be dependent on the pounds/year you require and your country of manufacture.
