Industrial rubber typically falls within the 40–80 Shore A range, though there is no single standard hardness for all types; components such as gaskets, seals, vibration dampers, and rollers may utilize different hardness levels depending on specific requirements. Temperature also significantly affects measurement results: heated rubber tends to soften—lowering the Shore A value—while cold rubber tends to harden, causing the Shore A reading to rise.
