Hardness

HARDNESS

The different Shore Hardness scales measure the resistance of a material to indentation. There are different Shore Hardness scales for measuring the hardness of different materials. These scales were invented to have a common point of reference.

The Shore A Hardness Scale measures the hardness of flexible mold rubbers that range in hardness from very soft 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.
