the most visible number on a silicone datasheet\u2014and one of the most misunderstood. Many teams treat it as a simple soft-versus-hard decision: In real applications, that linear logic often leads to sealing failures, user complaints, or parts that age far faster than expected. Shore A hardness is not a single-performance attribute. It simultaneously affects feel, sealing behavior, and long-term durability, and those effects frequently pull in different directions.
