    When we design pacifiers, safety comes first. Many teams focus on Shore A hardness. They believe harder silicone means stronger products. In real production, this idea often causes problems. Harder silicone can become brittle. Once a baby\u2019s tooth creates a small cut, the material may tear quickly. That small tear can turn into a choking risk. After years in silicone molding for baby products, I have learned one clear lesson. Tear strength matters more than hardness. This article explains why. I will break down the material logic, the lab testing, and the shop-floor decisions that lead to safer pacifiers. The Misunderstanding Around Hardness Shore A durometer measures surface hardness.
