General Info about (Shore Hardness Scale)

  • The Shore 00 Hardness Scale measures rubbers and gels that are very soft
  • The Shore A Hardness Scale measures the hardness of flexible mold rubbers that range in hardness from very soft and flexible, to medium and somewhat flexible, to hard with almost no flexibility at all. Semi-rigid plastics can also be measured on the high end of the Shore A Scale
  • The Shore D Hardness Scale measures the hardness of hard rubbers, semi-rigid plastics and hard plastics.
