Our pharmaceutical vial rubber stoppers are primarily made from bromobutyl rubber or chlorobutyl rubber, often with a silicone coating to enhance performance and ensure a sterile seal.
The silicone coating reduces friction during needle penetration, minimizes particulate generation, and improves the stopper's ability to maintain a sterile barrier, ensuring product integrity and safety.
Key specifications include coating type, color, diameter (in mm), flange thickness (in mm), and Shore hardness (Shore A). These factors ensure compatibility with your vials and meet regulatory requirements for pharmaceutical preparations.
